Question

What is the basic cause of induced current?

Answer 1

$\huge \mathtt \blue{ \underline{ \underline{Answer:}}}$

The most basic cause of an induced EMF is change in magnetic flux.

This can happen due to two reasons;

1. Placing the electric conductor in the presence of a changing magnetic field. As the EMF generated depends on either a small change in area vector or magnetic field, therefore this will cause an induction of EMF

2. 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.

★ Additional Information :

Induced EMF has several applications such as;

a) Its use in galvanometers

b) Its use in generators

c) Its use in transformers.

All three of these devices work on the principle of induction of electromotive force.
