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?

why am I just discovering him aaa I love how he presents and how articulate he is. not to mention how well and concise he explained it!!!! why is this 6min video way more clear than everything else I've seen up until now? 😭🙏 tysmmm

@@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 ...

@syedwarsi2409 4 года назад

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?

@erickerickson7665 2 года назад

Nope. A permanent magnet gets it's magnetic flux from it's atomic structure

As Erick said, although you can also induce an electric current inside a wire by moving a magnet near it, which is the basis for how electric generators work

I read an article about 3 years ago on twisted bi-layer graphene and ferromagnetism and a 1.2° twist being a magic angle to associated with ferromagnetism. 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?

Slide at 2:40: The geographic north pole of the Earth is actually a magnetic south pole. The magnetic north pole of compass needles points to the magnetic south pole of the Earth, thus to the geographic north pole.

You are right. Indeed the first drawing of the video shows correctly the south pole of the magnet on earth's north pole.

How does the magnetic field affect differently charged particles (e.g. protons and electrons)? Could you further explain this?

@lukakusekovic9185 4 года назад

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

North pole is actually a magnetic South, which is why north is north as it is attracted to the south magnetic pole

@kobiecamp1134 Год назад

Professor Dave Explains: I understand that Ferromagnetic materials like Iron has 4 unpaired electrons per atom, Cobalt has 3 unpaired electrons per atom, and Nickel has 2 unpaired electrons per atom. But how many unpaired electrons per atom is present in the actual magnet that's attracted to these Ferromagnetic materials?

@breakingphysics143 2 месяца назад

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

@helium73 6 лет назад

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.
