Magnets and Magnetic Fields

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?

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

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

My teacher is making me watch this for class

I've just finished this whole Classical Physics Videos. So grateful! Thank you so much Professor Dave!

Weird that a physicist is actually giving an explanation instead of answering absolutely nothing about the question as they usually do.

[제갈식]

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 ...

Thank you this is absolutely the best overview of how the things are interconnected and how they come together, I cannot express my gratitude enough!

Hey Proffesor Dave. Im in 11th grade now. I just finished your wonderful Classical Physics playlist. It was such well-explained and well put out. I loved your series so much. I cannot wait to move on to Modern Physics playlist now.

[kriptoniteXD]

Im almost 30 and dont know much about physics. Your videos are easy to digest! Thank you sir!

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.

Hey prof. Dave, I love your videos. I had a question. Is there an actual flowing electric current inside a bar magnet( not electromagnet)? Like if we touch the magnet will we feel a shock?

[dennisje]

Thanks for great content. Binchwatch the classical course. Modern course here I come!!!

Wonderful explanation for all, no matter what age.👍⭐

[picturesurears]

Best explanation I've found. Thank you very much!

[Theslimslayer]

For some reason magnetism is fascinating to me. Truly an interesting and unique phenomenon. Almost like a shaped, usable version of gravity

PLEASE PLEASE PLEASEEEE make more on physics professor Dave
