071 - Electromagnetic Induction

In this video Paul Andersen explains how electromagnetic induction occurs when the magnetic flux of an object changes. The magnetic flux is product of the surface area perpendicular to the magnetic field and the magnetic field strength. Microphones and generators are examples of devices that utilize electromagnetic induction.
