Objective: Generating a voltage pulse in a conducting loop by the motion of a permanent magnet

When a permanent bar magnet is allowed to fall in succession through a set of identical induction coils connected in series, a voltage is induced in each of the coils. The voltage amplitude increases from coil to coil as the magnet moves through each coil, as the velocity of the magnet increases steadily. However, the magnetic flux that is calculated by integrating over the observed voltage curve has the same value for all the coils.
