Magnets are highly misunderstood, and often interpreted as magic. But they're not magic! It's just science. Let's learn about what magnets are and what produces magnetism and magnetic fields so that we can sound super smart at dinner parties, yes?

@@nonyabiz62 It would certainly change a lot of things on earth. If F.e. earths rotations around itself slowed, days would be streched out (1 day on earth = 1 earth rotation around itself). That would change the enviorment in a lot of unpredictable ways you could theorize about yourself. If the magnetic field or earth changes, (i don't know why it would change much tho), it would have more consequenses. F.e. the magnetic field protects us from solar winds, and UV light. Properbly more stuff, but that was just what i remembered from class.

An electric field is generated from a stationary electric charge, a magnetic field is generated from a charge that moves at constant speed, and an electromagnetic wave is generated from a charge that is moving at an acceleration. On the other hand, a gravitational field appears in a stationary mass, and a gravitational wave appears in a mass that accelerates. But why is it said that nothing comes out of a mass that moves at constant speed? Isn't it possible that something unknown comes out of a mass that is linearly moving at constant speed? If it comes out and it is a force in the form of repulsion, dark energy is explained without dark matter. There are so many interstellar objects (planets, asteroids) in linear motion in the universe ...

We must know "Theory of Origin". The basic ingredient is a mass, imagine that even this mass has no characteristics of its own (no chemistry), just a mathematical mass. Entire Physics can be explained, if we have some knowledge, about this theory. You put up good point, where there is FIELD (strong or weak), there is FORCE; where there is FORCE, there is MOTION. Everything in Universe is in perfect motion (geometrical curve circle, ellipse, parabola etc). We must figure out, which force is responsible for all of these?

My question is: if that is true, what would happen if we stacked 300 layers of graphene with a 1.2° clockwise(or counterclockwise) twist creating a 360° lattice?

If you have a proton moving through the magnetic field put your thumb in the direction in which proton is moving, put your index finger in the direction of the magnetic field acting upon the proton and the directiom of the resulting Lorentz force on the proton will be pointing perpendicularly out of the palm of your palm. If you have an electron the first two steps are the same but the direction of Lorentz force acting upon the electron will be pointing perpendicularly in the opposite direction than it would on proton, so it will be pointing into the palm of your hand

oh god, I just found a massive problem the north pole is the southern end of the magnet. and the south pole is the northern end based on how we named magnets based on bar magnets pointing north, we call the end that points north the north end of the magnet and vice versa but magnets attract opposites, that means if the north end of a magnet is attracted to the southern end of another magnet, which means that since the north end of a magnet is attracted to the NORTH POLE that means the north pole is the southern end of the magnet

electromagnetic field. So maybe light is just a realigning of the magnetic fields (grid coordinates). Lines need to line up so when something moves the grid coordinates need to update. Since space and the coordinates are the same thing we are only seeing a portion of what's actually taking place. Anyway we seem to see that light and magetism are the same thing but have we even unified light and magnetism? We hardly seem to equate the two even today. It's like the magnetic part of light is ignored. It occurred to me that light has a direction but it also has a wave-front.
