A current can be induced in a conducting loop if it is exposed to a changing magnetic field. In other words, if the applied magnetic field is increasing, the current in the wire will flow in such a way that the magnetic field that it generates around the wire will decrease the applied magnetic field. ...

What is the basic cause of induced current?

The most basic cause of an induced EMF is change in magnetic flux. ... Placing a current carrying coil that is moving constantly in a stable and static magnetic field. This will cause a change in the area vector and hence, EMF will be generated.

How can induced current be increased?

The magnitude of the induced current can be increased by:

Taking the conductor in the form of a coil of many turns of insulated wire. Increasing the strength of the magnetic field used. Increasing the rate of change of magnetic flux associated with the coil.
