Experiment: 2
In his second experiment, Faraday arranged two bar magnets in V shape..
At the other open end of V shape he kept one soft iron rod with an insulated copper wire wound around it. A galvanometer was connected with the conducting wire.
He observed that the galvanometer shows deflection on moving the end of upper magnet up and down. As the magnet moves nearer to the rod, magneic flux linked with the coil increases. When the magnet touches the iron rod flux associated with the coil becomes maximum and as the magnet moves away from the rod, magnetic flux in the coil decreases
From this experiment faraday concluded that to induce electric current in a coil, change in magnetic flux is required and not the flux itself
