Introduction

Summary

Induction occurs when the flux of B through a closed loop varies. The orientation of B relative to the loop surface varies.

Keep in mind that this experiment is the basis for the principles underlying many power plants.

Goals

• To illustrate a simple and historic experiment performed by Faraday in 1831 to study the laws of induction.
• To emphasize that whether it is the magnet or the conducting loop that turns, the effect is the same.
• To introduce the problem of relativity that was resolved by Einstein 80 years later.
