Khan Academy: Magnetic Force on a Charge

A video reviewing over an example problem to determine the size and direction of the magnetic force on a proton moving through a magnetic field. [10:48]

Class members use mathematics in order to better understand magnetic forces and their interaction on charged particles. After a demonstration of the interaction between a magnet and an electron beam using a CRT computer monitor,...

Find out how the formula F=ILB is derived in this video. Also, learn how to use the formula to calculate the force on a current carrying wire.

This video builds off of part 1 where the radius of the circle traveled by the proton calculated by using the formula for centripetal acceleration. [10:39]

Sal Khan shows how to determine the magnetic force between two currents going in the same direction. [10:59]

Learn how to solve problems to determine the magnetic force between two currents going in opposite directions. [11:01]

After high schoolers have learned about electromagnetic induction, they can solve these 10 practice problems. They calculate magnetic field strength, magnetic force, electromotive force, and output voltage. This is a choice option as a...

In this interactive tutorial students will explore magnetic force. Students will observe interactions of magnets and study magnetic fields. The source of magnetic properties is believed to be moving charge. Since moving charge produces...

This passage will test your knowlege on normal forces.

Examine how a magnetic field can be created in a wire carrying current with this video. [9:41]
