Electromagnetism - Magnetic Force: The Four Fundamental Forces of Physics #4b

In this final segment on the four fundamental forces of physics, Hank tackles the magnetic force, the second of the two ways in which electromagnetism is apparent in the universe.

lol you know the featured video is generally based on your cookies and past browsing

What he said

You know what else is magnetic... You're living on one!

What I heard

You know what else is magnetic... You're sitting on one!

My chair is magnetic???

[Havoc2003414]

Lol, yep. my ears (or mind) played the same trick on me.

I've already been taught this in school, but some how it's just a million times more interesting when explained by Hank.

[rasanja dampriya]

Ouch ! lol

[dominic8037]

so is a tesla device the opposite of an electro magnet?

[YellowCountry Can]

may the force be with you

[danysoultakerftw]

Wich forces are related when you dope a piece o sylicon to make a diode or a CMOS, this should cover the better understanding about the technological explosion about the 30 or more past years, from valves to semi-conductors, this should be interesting

[Irie Nature]

That explains the "brain on porn" episode! 

[Tunatunatun]

It is a physical thing, just not one you can percieve directly with your main senses, what I described is just my way of understanding how it works, or at least how it was explained to work. Remember, magnetic fields are caused by moving charges. Most magnets are electrons spinning in an oriented way, look or watch any explanation of a coil's magnetic field, which indicates why the field lines point and go the way we see dipoles.

[RajaTheFish]

I've always thought of magnetism and electrostatic as two parts of the same thing... I don't understand how you could see it much differently....
