Introduction

Summary

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

Goals

  • To illustrate a simple and historical experiment made by Faraday in 1831 to study the induction's law.
  • Insister sur l'invariance du phénomène selon que c'est l'aimant qui tourne devant la spire ou la spire qui tourne devant l'aimant.
  • Introduire le problème de relativité résolu par Einstein 80 ans plus tard.
