Film Theory: Phineas and Ferb – Doof’s BIGGEST MISTAKE!


Phineas and Ferb is now ten years old, meaning
that those of you who grew up watching it are ready to enter the dating scene. So in the hopes of helping you find your own
true Isabella, it’s time to welcome you back to MatPat’s Guide to Finding the One:
Animal Magnetism Magnif-inator Edition. “Hey baby, is there a magnet in your pants? ‘Cause my Magnetism Magnif-inator can’t
resist your buns of steel.” “Have you seen Perry?” “Is that the name of your platypus?” “No.” “Oh. Ooooh…” “Hey girl, has anyone ever told you that
you’re a Babe-inator with your settings cranked up to STUNNING?” “What’cha doin?” “You.” Hello, Internet. Welcome to Film Theory, the show that looks
at the animated characters who do crazy science and does even crazier science off of their
work. Today, I’m returning to the world of Phineas
and Ferb, which we did an episode on a couple months back. If you haven’t seen that one, definitely
check it out–we basically prove that Dr. Doofenshmirtz is secretly the good guy, a
sleeper agent for the OWCA. Episode is linked in the upper-right hand
corner if you’re SO EXCITED that you need to watch it RIGHT NOW well you know where to find it…otherwise, just click
the link at the end. But even though that episode talked about
how ol’ Dr. Doof’s not such a bad guy after all, it doesn’t mean he’s not without
a few flaws. Hey, we’ve all got our shortcomings…it
just so happens to be that Dr. Doofenshmirtz’s is literally his entire job. Starting from the very beginning,
episode 1 of the series, we see how this so-called evil scientific genius basically doesn’t
even science, bro. This guy has hundreds of inventions over the
course of the series, but the Magnetism Magnif-inator from the pilot episode is not only the first
we see, but it’s also one that gets referenced time and again over the next four seasons. Quickly, we must separate the magnet from
the Magnifinator before it is too late…Is it just me or is this a serious déjà vu
moment? I feel like I’ve totally been here before.” “That’s it! Agent P, you’ve got to get to that time machine
and go back to the past, right before that giant tin foil ball put you in a full body
cast for eighteen months.” Basically, the Magnetic Magnifinator is a
super-strong magnetic laser that somehow sucks in a magnetic field on one end, amplifies
it on the other, AND manages to shoot it directly at a target, which in this case is all the
skyscrapers on the Eastern Seaboard. Dr. Doof’s plan is to cover the Eastern
Seaboard in tinfoil, then use the Magnetism Mangif-inator to pull on all the skyscrapers
on the East Coast so that everything on the East is pulled toward the West. His goal is to ultimately wants
to reverse the rotation of the Earth. Why? Would you want to reverse the rotation of the earth? …Well, that’s still up in the air. “You may ask yourself, why would he do this? Well, let me just answer that question, I
haven’t really worked on all the bugs yet. I mean, tin foil alone costs a lot.” But is Dr. Doof’s most infamous invention
of the series a scientific success or just a load of electromagnetic excrement? While it seems like this invention is a complete
disaster in every way, today’s episode actually looks at the science behind the Magnetic Mafnifinator
to reveal just how advanced Doof is…and probably more accurately how smart the creators of the show were in
designing this thing…and then I’ll just talk about the critical flaw that makes it all fall apart. Get ready –today is going to be one polarizing episode. Polarizing episode. Get it? Like Magnets? Hey, I haven’t ever covered magnets, so
I’ve got a lot of pent up puns to unleash So even though he doesn’t know WHY he’s
doing it, it’s clear Doof wants to reverse the rotation of the Earth. But already there’s a huge problem with
that — pretty much the first thing you learn in physics: the concept of closed systems. Yeah, dust off like the first 10 pages of
your high school physics textbook for that one. In this case, the Eastern Seaboard that Doof
is shooting the Magnificator at and his own headquarters are both part of what’s called
a “closed system.” According to classical physics, exerting a
force inside a closed system doesn’t change anything about the system relative to its
surroundings. In easier-to-understand terms, if Doof’s
goal is to change the rotation of the early in space he’s never going to do that by
shooting one thing on the Earth at another thing still on the Earth. Trying to do this would be like trying to
move a car by putting a moving tire inside the vehicle — nothing is going to change. The only way for a car to move is for it to
exert force against something external, like the road. By the same token, the only way to move an
object like the Earth through space is for the object to exert a force against something
outside of itself. When you’re able to do that, it’s called
an OPEN system. But in order for magnets to affect anything
about the Earth’s rotation, he’d need to be aiming the Magnifinator at the planet
next door, not some tin foil a few buildings away. “As a lazy tailor would say, suit yourself!” But ok, so cat’s out of the bag that he
can’t change the rotation of the Earth. But maybe he could have done something else
interesting with the Magnifinator instead? As it turns out, at the time of the premiere
episode of Phineas and Ferb, Dr. Doofenshmirtz was actually eight years ahead of his time
with the Magnifinator. No joke! Believe it or not, astrophysicists have spent
almost the last decade trying to catch up to exactly what you see him doing in this
episode. Think that’s nuts? Let’s take a closer look at the Magnetic
Magnificator and see just what’s going on here: On the one end you have a huge magnet–seems
to make sense if you’re trying to suck the buildings right off the pavement with magnetism,
but if you know something about magnetism you’d immediately notice two huge problems
right off the bat. The first is that regular magnets don’t
have directionality. They have poles, but that doesn’t make them
directional. You can’t point a magnet like a gun and
go, “Bang! I just shot you really hard with this magnetic field!” When you create a magnet, it honestly just
kind of sits there and emanates a magnetic field all around itself…not exactly threatening. Problem two is that even if he has a strong
magnet over here, it won’t do anything to those buildings over there. Magnetic strength works by the inverse cube
law, which means that as two magnetic objects get farther away, their attraction drops off
exponentially. An object that is twice as far away from a
magnet will require 8 times as much strength to attract it. Increase the distance by ten times, and you’d
need to increase the strength by a THOUSAND times to compensate. Dr. Doofenshmirtz is trying to use his magnet
to pull on buildings a kilometer away, which is basically impossible for any magnet that
exists on Earth. The strongest magnet that currently exists in the world today is located
at the National High Magnetic Field Laboratory in Florida, which has a magnetic strength of 25 Tesla
(that’s the unit used to measure magnetic field and not,you know, the car) — that’s half a million times stronger
than the Earth’s own magnetic field, which seems ridiculously strong, but remember that
we as people living on the surface of the Earth don’t even feel the Earth’s magnetic
fields and the only way we ever even notice it is if we’re using an instrument sensitive
enough to detect it like a compass. So to get around these problems Dr. Doof either
needs to focus that magnet or find a way to get the magnetic field a heck of a lot closer
to those buildings. And bizarrely enough, that’s exactly what we see him doing in the show. You heard that right, Dr. Doof is doing exactly
the right thing. “I did not expect that…” Take a look at the other parts of the Maginifinator,
namely this tube here and what looks to be a concentrated magnetic laser beam that he
shoots toward the city. He might not have known it at the time but
these are now real things that the most advanced physicists in the world are still developing. The first is this magnetic pipe, or hose,
which is 100% a real thing. By placing a magnetic field close to the opening
of a specialized tube, theoretical physicists, or just “Theorists” as I like to call
them, have actually managed to preserve a magnetic field over much longer distances
than the field would exist by itself. Right now they believe they could actually
preserve 90% of a magnetic field in a magnetic superconductor hose, transporting magnetism
in a way that previously seemed impossible. The other thing that’s going on here is
potentially even more exciting because it doesn’t just involve magnets, it involves
lasers, which are just inherently cool. We can see that the Magnifinator doesn’t
just seem to be a plain old magnetic field generator, it’s a laser beam at one end. Once again, Dr. Doof is actually way ahead
of his time, creating what would have been the world’s first super magnet laser, something
that, as of 2016, is being built for the first time ever. These magnet lasers are pretty much exactly
what they sound like: ultra powerful lasers that have the special ability of also creating
extremely powerful magnetic fields–thousands of times more powerful than any field humans
have created in the past. Basically these thing would be a lot like Metroid grapple beam. The physics behind these things is incredibly
complicated and if you’re a Faraday Effect aficionado I invite you to dive into these
things in the comments, but for what we’re talking about right now I’m basically going
to boil it up to the very top level. Lasers–which are basically streams of super-energized
electrons–start to get all kinds of special properties as you turn up the intensity of
the laser. One of the special properties that starts
to happen is radiation friction, or RF. This is basically the friction of electrons
at incredibly high energy levels, which gives you more than just atomic rug burn, it actually
creates an ultra-powerful magnetic field around the laser beam. Again, this is the made-for-Youtube version
of this incredibly advanced science, so if this sounds interesting to you, have a look
at this stuff, it’s literally as close as humans get to magic. Anyway, what you come out of this process
with is a magnetic field on the order of 1 Billion Gausse, which is a big number but
doesn’t mean a lot if we don’t have anything to compare it to. So for comparison, an MRI machine creates
a magnetic field of 70 thousand Gausse, which is enough to interfere with pacemakers, metal
prosthetics, or any other electronics that end up inside it. And this magnetic field is in the billions
of Gausse, basically an astronomic level, and can do things like contain nuclear fusion
and rival the magnetic strength of a neutron star. You heard that right, Doof created a device
that rivals the power of STARS! So yeah, with that kind of magnetism, Dr.
Doofenshmirtz could definitely do some serious damage. “If you give me another chance I promise to hurt you in the right way, with
cartoonish physical violence and elaborate traps made out of strange things I bought
over the internet.” OK, so far we’ve found a way to make the
Magnifinator possible, in theory. But here’s where it all comes undone: To
create what he thinks will be a super strong magnetic attraction, Dr. Doofenshmirtz covers
all the skyscrapers on the Eastern seaboard with tin foil. Let’s see what happens at the big moment
when he’s going to rip them all up! “Pull the Eastern Seaboard thereby reversing rotation of the – “Oh, well that didn’t work.” You bet it didn’t my little Doofle-pants. Get your dipoles straight, my friend, you
created the world’s first magnetic hose, hooked up to the world’s most advanced magnetic
laser in history which can literally harness the power of effing STARS, but you forgot
one thing…one CRUCIAL detail in your ENTIRE plot. Tin foil isn’t magnetic. While it’s true that metals like iron, nickel,
and cobalt are attracted to magnets, not all metals are. Ferromagnetism is the property that we use
to describe things that are magnetic. What we refer to as “tin foil” isn’t magnetic
and…isn’t actually made of tin, at least not today. Back in the 1800’s, actual tin foil sheets
were commonly used, but when it came to covering food, they left everything they covered with
a metallic flavor, which is why in the 1930s and 40’s tin was replaced with cheaper,
tastier aluminum. But while switching to aluminum may help Doof’s
tuna sandwich stay fresher, it’s not going to help him create mega-magnets any sooner,
since neither tin nor aluminum are magnetic. In fact if anything, covering these buildings
in foil is going to make it harder for the pieces of these buildings that ARE magnetic,
like all the steel, iron supports, or pipes, to all come ripping out. He’s literally creating a barrier against
his own magnet laser. And yes, technically iron foil does exist
and would be magnetic here, but Dr. Doof specifically says he uses tin foil because “I mean, tin
foil alone costs a lot.” If he were to upgrade to iron foil, to cover
even the one city section we see on screen in the episode, which is just a tiny fraction
of the real Eastern seaboard, it would cost at least $742,500 and we know realistically
that for the entire East Coast he’d have to repeat this dozens or hundreds of different times. So in the end, despite all the resources and
incredibly advanced technology Dr. Doofenshmirtz has at his fingertips, from ultra lasers to
theoretical physics, his whole plan is undone by not paying attention to the most fundamental
rules of magnetism. The stuff that we learn in like third grade! And instead of taking over the world in the
very first episode, we got four more seasons of Phineas and Ferb science to dissect. So don’t worry, we’ll have plenty more of
his plans to FOIL over on this channel, so make sure you activate the SUBSCRIBE-INATOR you see
on screen right now so you’re around as we cover more classic Disney Channel and Nickelodeon
shows, everything from Danny Phantom and Fairly Oddparents to Drake and Josh and Zach and
Cody. Here’s our previous Phineas and Ferb episode on the left
and remember, that’s just a Theory. A Film Theory! AAAAAAAAAND –

  1. I mean, lasers do work thanks to the energy an electron owns, but what comes out of the laser is a straight line of photons resulting of photons creating other photons by taking away the electrons' energy, and what is inside isn't so much electrons as it is full atoms
    Did I miss something here ? Cutting the explanation short doesn't prevent the idea of being correct in the few you describe
    Or I'm wrong, in that case I'm a bad boy, hit me with some text block that'll make my narcissistic mindset unable to hit back

  2. Little did we know the people who made this show are actually working in Area 51 and know how to make the earth turn the opposite way. They just put it in a kids show so no one would notice.

  3. WAIT A MINUTE! if o.w.c.a copied doofensmerts blueprints including the magnetic magnifinator and doofensmerts created magnet lasers first could that mean that o.w.c.a's copied blueprints of the magnetic magnifinator somehow got loose and people are building magnet laser's IRL!

  4. Wrong, aluminum is magnetic, everything is magnetic, is just that is paramagnetic and not ferromagnetic, and paramagnetic objects are atraccted to magnets.

  5. MatPat: I've never talked about Magnets before.

    Recommendations: Magneto's Fatal Weakness.

    Me: visible confusion

  6. I'm only 10 years old and at the time I'm watching this it's 12 years old now but I've seen every episode like 50-60 times

  7. This made me laugh, intrigued, and so happy!!! <3
    ;3 I'm coming back to old film theories and I'm LOVING it LMAO !!!!!!!!! 🙂

  8. Fineas and ferb always scared me… They are too lucky and its disturbing. And their poor poor sister 😭😭😭
    Totally not a show for kids.

  9. imagine being a time traveller,going back in time,making a cartoon about the future only for scientists to figure out 8 years later

  10. So, lightsabers dont cut, they attract atoms so close to eachother but at the same time far enough away to make a small explosion cutting the attacker.

  11. Omg Mat pat you should have already said something about magnets I haven’t seen anything magnet 🧲 stuff sense I was In middle school

  12. MatPat: the strongest magnet on earth that currently exists in the world is located at the National High Magnetic Field Laboratory in Florida.

    Me: ha, no. The strongest magnet on Earth is the Earth itself. It’s just basic science

    Edit: why am I posting a comment on a game theory video that came out a year ago
