Dear Hank, congratulations on your show and your team! This series in particular is awesome, one of the best you produced. Kind Regards. Pietro

[@samovarmaker9673]

"You know what else is an electromagnet? You're living on one!" Lol I'm watching this from ISS

[@matthewgranstrom1579]

+New User ISS is a rotating hunk of metal in a magnetic field. That induces current, thus inducing magnetism in the ISS. Additionally, on ISS there are several modules, as you well know, and many of them contain various electromagnets for scientific purposes.

[@samovarmaker9673]

But is the ISS magnetic like the Earth with a north and south pole?

[@matthewgranstrom1579]

+New User all magnets have both poles

Man that was a roller-coaster ride.

[@electricmovement0779]

yes it was

[@guilhermesouza3280]

As An electrical enginner, I find his videos very informative and funny. Videos like these would be very useful back when I was starting college, to backup all the concepts provided by the books. If you guys know where I can find similar content, maybe deeper in these scientific subjects, please let me know.

lovely series on 4FFs... does not get any more comprehensive than this.. love scishow!

[@fortunne]

I have learned so much from watching SciShow. So much cool stuff. This is way better than school.

[@oliverlovelltas]

Thanks Hank, loved this series! I'd like more info on how photons are the electromagnetic force carriers, and how this works. You talked about how gluons play a part in the strong interaction, and how W and Z bosons change quark colour in the weak interaction, could you do the same for photons? That would be amazing! Ollie.

[@Dragrath1]

magnetism can be though of as a relativistic lorenz transformation of electrostatics (juts like what gravity in relativity does to length and time) in both cases when an object is stationary from the perspective of your reference frame the lorenz transformation term drops off which in the case of electromagnetism reduces the problem to electrostatics. Now when velocity is added their is a shift which is observed as magnetism. This is probably one of the most mind blowing things from my electromagnetism class for more information check Introduction to electrodynamics by David J. Griffiths chapter 12. Yes this is a textbook but a very good one pretty much the best E&M textbook according to pretty much any professor for undergraduate E&M, assuming a strong calculus background as E&M involves tons of integrals.

[@tokyowanderer009]

FINALLY! I was waiting a whole week for Hank's last fundamental force video to show. 'Twas worth the wait.

[@Pyrite777]

I learn so much from this show. You should do a show about the singularity.

Great video filled with info. Keep up the great work.

[@finanzalex]

Thank you for sharing the knowledge. Magnetic force always fascinated me.

[@jinxblau]

hi SciShow! Iv'e been studying a bit on electromagnetism and learned that a magnetic field is a phenomenon created when an electron accelerates in relativistic speeds. what i don't understand is how this creates a stationary magnetized object (aka a magnet) and i would love to see you make a video on that topic thanks for being awesome and rock on

[@mathmetics12345]

There is a video by veritasium that explains how stationary magnets work :D

[@Coolman-ww9vg]

It probably just has to do to overall realities charges and also in that both an electron and photon act as waves that have both (and positrons if we’re going in depth)

[@FlipUpCoconutKing]

Everytime you mention the Earth's magnetic field, I tend to hug the floor. Thank you Earth's magnetic field

@@gpaps7787 THE ULTIMATE (AND CLEAR) MATHEMATICAL UNIFICATION (AND PROOF) REGARDING PHYSICS/PHYSICAL EXPERIENCE IS NOW DEMONSTRATED, AS E=MC2 IS F=MA: TIME DILATION ultimately proves (ON BALANCE) that E=mc2 IS F=ma, as ELECTROMAGNETISM/energy is gravity. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. (Importantly, balance and completeness go hand in hand.) The stars AND PLANETS are POINTS in the night sky. NOW, A PHOTON may be placed at the center of WHAT IS THE SUN (as A POINT, of course); AS the reduction of SPACE is offset by (or BALANCED with) the speed of light (c); AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Indeed, ultimately and truly, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=MC2 IS F=MA; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. GREAT. Accordingly, INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/PHYSICAL EXPERIENCE; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. It ALL CLEARLY makes perfect sense. Gravity IS ELECTROMAGNETISM/energy. E=mc2 IS F=ma. ELECTROMAGNETISM/ENERGY IS GRAVITY. E=MC2 IS F=MA. GREAT !!! Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites, AS E=mc2 is F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Consider THE MAN who is standing on what is THE EARTH/GROUND. Touch AND feeling BLEND, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. The stars AND PLANETS are POINTS in the night sky. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Accordingly, the rotation of WHAT IS THE MOON matches it's revolution. Great. MOREOVER, a given PLANET (including what is THE EARTH) then sweeps out equal areas in equal times consistent WITH/AS F=ma, E=mc2, AND what is perpetual motion; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. Stellar clustering ALSO proves ON BALANCE that E=mc2 IS F=ma, AS ELECTROMAGNETISM/energy is gravity. Objects (including WHAT IS the falling MAN) fall at the SAME RATE (neglecting air resistance, of course), as E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/energy is gravity. ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 IS F=ma. THE DOME of a PERSON'S EYE is ALSO VISIBLE. (Notice the flat AND black space of what is THE EYE.) The stars AND PLANETS are POINTS in the night sky.

The Earth's electromagnetism needs its own show. Really; it's awesome. I could do a whole video on it.

[@SS-ww2qd]

Great series!

[@MrPhysicsRocks]

I'm a physics teacher and I would have loved to show this to my students, but don't think I should because of your conflating electric charge with magnetic poles. Also, your calling a permanent (fridge) magnet essentially an electromagnet is wrong. Most permanent magnets are created by applying a strong magnetic field across them, not running current through them. This is because materials that are ferromagnetic are not that way because of electric charge; it is a quantum effect (every electron is its own little magnet, see magnetic quantum number). (And yes there is an electromagnetic effect from the electron orbiting the nucleus, but it is small).

[@JanMichaelCruz1]

Pwned

[@shannonlaing9938]

Isn't that the point hes making though, that the sum of all the small electromagnetic forces of the electron-nucleus interaction that makes a permanent magnet is analogous to using a lot of small electromagnets to make one big one?

[@MrPhysicsRocks]

No - the electron itself is a magnet, it has nothing to do with the interaction with the nucleus

[@Icedpyro21]

if you can make magnets with electricity can you make electricity with magnets??

[@Mandragara]

Yes, it's called a generator.

[@Icedpyro21]

i realize that the statement i made is really poorly worded and thats not really what i ment

[@albusdumbledore8723]

What did you mean?? That is how all the power you are using is generated! Faraday discovered that running a magnet through a magnetic field produces an electric current. Coal/Nuclear/Natural Gas etc. Power plants generate steam and turn a turbine, and power a generator that pushes magnets through magnetic fields, generating electric current. Not trying to patronize, just clarifying your silly question.

[@Icedpyro21]

i ment using magnets to spin the magnet that's inside the coil.

[@albusdumbledore8723]

how is that a different phenomenon?

[@CBoy92]

Cool, thanks. Looks like that was exactly what I was looking for.

[@oisingor]

holy shit adam your comment is on the front page of scishow!!!!! and all this came from us trolling one day, im so proud of you

[@LootFragg]

This looks so much better. Forces don't wear out. Every object in your living room applies a force onto the ground it stands on, so do you. Even when you're not doing a thing. But that is not finite, so they won't start floating at some point. Work is finite as it's an equivalent to energy. Force doesn't exactly run out, it just is, spoken simplistically. Now I understand what you mean by "infinite force". Yes, those fundamental forces always were and always will be. They make everything.

[@TheWyrdSmythe]

Magnetism turns out to be based on electron spin, so those refrigerator magnets are a visible instance of quantum physics. I've always thought that was kinda cool. You don't normally see quantum effects in daily life. :) Good series!

[@KatherinePierce_81]

Once you see it you can’t unsee it

[@YoutubeConnoisseur]

I felt accomplished knowing that I completed watching this series :D

[@DownThereForDancing]

Hank, I've recently read and seen a lot of stuff about Richard Feynman and his work, particularly on quantum electrodynamics. Will you be doing a show on QED? I'm wondering - how far have we come from QED? Do we have a deeper understanding of electromagnetism or is QED still our best explanation?

[@gates10611]

Amazing show, i have a question about which direction lightning travels. From the clouds to the ground or from the ground to the clouds ?

[@borbo23]

I favorited this whole series to show to my cousins to help explain these forces to them. :D

[@DragonNoirification]

Could you do an episode on the attempt to unify the forces into the Grand Unified Theory? I think it would be a great extension of the 4FF series.

[@loulyaalove]

Good job ❤❤❤

[@ajukrishnan1005]

Thank you Hank

[@GuerrasLaws]

Force (physics) does not exist physically in the same way that an object with mass, thus making it “not” the initial cause of pushing, pulling, shaping objects, motion, work or being a Vector Quantity (Magnitude + Direction). In physics, the word, “Force” as we know it, turns out to be nothing more than an expression to express an idea, like one would use the word “Love” to express one's feelings. But, physics and in mathematics, still use “Force” as thou it were something physical that could enable the initial cause of motion making it counterintuitive. Example: Without applying the Energy from within you, choose an object of your choices to push and pull by simply applying “only” the Force or Net Force. Meaning that Energy (applied energy) is the origin of motion and not “Force”. Once Energy (E) is applied, it creates what is known as Momentum (p). When this Momentum (object in motion) comes in contact with another object(s), it makes a surface contact that will enable you to push and pull. Example: Ep=ma, Ep=mv and so on. Note: Ep is not to be confused as Kinetic Energy in any way. Momentum represents things like work, wave, gravity, light, lightning, tsunami, earthquake, current, electricity, motion, magnetism, etc. Without Energy, there is no Momentum. Without Momentum, there is no surface contact on an object(s) to push, pull, work, shaping objects, motion, etc. Momentum does not and cannot exist without the applied Energy that creates it. Energy and Momentum or “Ep” is the one and only common denominator that links all fundamental forces of nature. Without Ep, all fundamental forces of nature would be inert and non-existence. Energy is energy, but it’s when Energy (E) is being applied that creates the Momentum (p) making it the initial cause of motion. Example: Ep. By applying the right amount of Energy, nothing is immovable or unstoppable. ~ Guadalupe Guerra

Big Sub

[@Tunatunatun]

A magnetic field can be described as invisible lines flowing out from the north pole and turning back and into the south pole, in the smoothest way they can but not too far. In a magnet [N-S], when opposite poles meet: [N-S][N-S], lines flowing from the inner north go directly into the inner south, smoothing the field around, and lines from the outer north go around a bigger, smoother pattern into the outer south. As each magnet by itself has a sharper path, they 'fall' together with some force.

Question: What is the single most basic thing that we know of? Is it an electron for being the smallest of the main parts of an atom? A quark for being the composite parts of the two biggest parts of an atom? The 4FF for holding everything together? This is not about importance, it is about what makes the base code of the universe.
