Two separate but nearby coils are mounted along the same axis. A power supply controls the flow of current in the first coil, an

d thus the magnetic field it produces. The second coil is connected only to an ammeter. The ammeter will indicate that a current is flowing in the second coil:.

The ammeter will indicate that a current is flowing in the second coil only when current changes in the first coil.

<h3>Induced emf</h3>

An emf is induced in a coil placed in a magnetic field when a current carrying conductor moves in the field.

emf = NdФ/dt

where;

dФ is change in flux of the field
N is number of turns
dt is change in time

Thus, the ammeter will indicate that a current is flowing in the second coil only when current changes in the first coil.
