Magnetic force on a charge - Khan Academy
We know a little bit about magnets now. Let's see if we can study it further and learn a little bit about magnetic field and actually the effects that they have on moving charges. And that's actually really how we define magnetic field.

Khan Academy
These magnetic fields can be used to generate magnetic forces. Oppositely, when magnetic fields are changed around charges, they can create moving electric charges, or electricity. Both of these phenomena are called electromagnetism, which is used in …
Are 2 magnets stronger than 1? - Khan Academy
How does the magnetic field change when you add more magnets? Does it get stronger? Like would we draw the magnetic field lines closer to each other?

Magnetism is a force of attraction or repulsion that acts at a distance due to a magnetic field.
Magnetic dipoles & dipole moment - Khan Academy
The magnetic dipole moment is a vector quantity and its direction is given by the right-hand thumb rule. Magnetic dipoles are different than electric dipoles in that, there are no magnetic monopoles, only dipoles.
