A wire is moved through a strong magnet and the induced current is shown on the galvanometer.
A coil is placed in a strong magnetic field and a galvanometer will register the current produced as the coil is rotated.
A coil is connected to the galvanometer and placed near a coil that is connected to a DC supply through a reversing switch. An induced current is indicated when the flux changes.
Questions:
How would the effect be made stronger?
