Electromagnetic Induction

Demo

A coil of wire, an analog voltmeter, and a small magnet

Concept Overview:

1. Interaction of a magnet through a coil of wire creates current.

Lecturer Procedure

Task(s) Expected Result
1. Move the magnet through the coil. Voltage reading changes dramatically (needle moves 1 direction)
1. Move the magnet through the coil from the opposite direction. Voltage reading will still change dramatically, but the needle will move in the opposite direction.
