Answer:This involves generating a voltage by changing the magnetic field that passes through a coil of wire. ... If the magnet is held stationary near, or even inside, the coil, no current will flow through the coil. If the magnet is moved, the galvanometer needle will deflect, showing that current is flowing through the coil.
