Question

state two ways in which current induced in the coil of a generator could be increased

Answer 1

1. Using a stronger magnet

2. Increasing the number of coils

3. Increasing the speed of rotation of the coil

Answer 2

The current induced in the coils of a generator can be increased in the following ways:

1. Increase the number of windings/turns of the coil.

2. Use a stronger magnet to induce the current or move the existing magnet faster.

According to Faraday's law, the voltage is directly proportional to the rate at which the magnetic field changes and also the number of turns of the coil.Therefore, increasing both of these leads to an increase in the voltage and thereby the induced current.
