But we're defining magnetism in terms of the effect that it has on a moving charge. And that's a bit of a clue. And we'll learn later, or hopefully you'll learn later as you advance in physics, that magnetic force or a magnetic field is nothing but an electrostatic field moving at a very high speed.
Magnetic force on a moving point charge is centripetal force. Point charge movement within a curved path (windings in an inductor) increases magnetic energy per current, because the curved path increases inductance.
In the last video we learned-- or at least I showed you, I don't know if you've learned it yet, but we'll learn it in this video. But we learned that the force on a moving charge from a magnetic field, and it's a vector quantity, is equal to the charge-- on the moving charge...
When the charges are in motion, an extra force acts on them. This extra force is called the magnetic force. The magnetic force between two charges q1 and q2, moving with velocities v1 and v2, is equal to.
It was later shown that all charged particles moving in a magnetic field experience a force. The force F acting on a charge q moving with velocity v is perpendicular to the directions of both v and B and is given by the following cross product.
