Question

explain different ways to induce current in a coil ?​

Answer 1

The different ways to induce current in a coil are as follows:

i) If a coil is moved rapidly between the two poles of a horse-shoe magnet, then an electric current is induced in the coil.

ii) If a magnet is moved relative to a coil, then an electric current is induced in the coil.

FORMULA OF INDUCED CURRENT

Ohm's law (V = IR) can be used to determine the induced current in the loop.

Transformers are devices that increase or decrease voltage based on the number of loops of wire around primary and secondary coils on opposite sides of an iron core.
