    Michael Faraday first discovered Electromagnetic Induction in 1830. His experiment that proved this the following: H e moved a permanent magnet in and out of a coil or a single loop of wire. And it induced an Electro M otive F orce or emf. In other words, the moving magnet produced a Voltage, and therefore a current. Michael Faraday’s famous law gives answer of the question of the dependence of the voltage: T he magnitude of the voltage is proportional to the rate of change of the flux. It is false that the voltage can not be increased by moving a magnet towards a coil. It is increased.
