To me, there’s two ways you could interpret that, one is what are the effects of magnetism which we learn on high school physics, the other other is why does magnetism have those effects which is more something you’d learn in an undergraduate physics or chemistry degree.

The answer to why they have those effects would grant you a Nobel prize.
