Unit 5: Electromagnetic Induction
You learned that stationary electric charges produce electric field, and moving electric charges (that is, electric current) produce magnetic field. In this unit, you will find out that the reverse is also true: changing magnetic flux produces electric field, or induces electric current. This is the phenomenon of the electromagnetic induction, which is a basic principles in such devices as generators of electric power, electric motors, and transformers.
Completing this unit should take you approximately 13 hours.
