How can one increase the strength of induced current?

The strength of the induced current increased when the strength of the magnetic field increases. It will also increase when the number of turns is increased or if the speed of the conductor increases.

Induced current

If a coil of wire is placed in a changing magnetic field, a current will be induced in the wire. This current flows because something is producing an electric field that forces the charges around the wire. The induced current depends on both the area of the coil and the change in a magnetic field.

The magnitude of the induced current can be increased by:

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