Question

Two circular coils A and B are placed to each other. If the current in the coil A is changed, will some current be induced in the coil B? give reason​

Answer 1

As the coil B is situated near coil A, it also experiences the magnetic field. As the current in coil A changes, the magnetic field associated with it also changes. Hence, the magnetic field around coil B also changes. Due to change in magnetic field around the coil B, a current is induced in coil B.

Answer 2

$\huge{\underline{\boxed{\sf{\purple{Answer}}}}}$

Explanation:

"Yes, it's because of electromagnetic induction."

✳️The induction of an electromotive force by the motion of a conductor across a magnetic field or by a change in magnetic flux in a magnetic field is called ‘Electromagnetic Induction’.

✳️When a bar magnet passes through the snaking, the voltage is measured in the circuit. The importance of this is a way of producing electrical energy in a circuit by using magnetic fields and not just batteries anymore. The machines like generators, transformers also the motors work on the principle of electromagnetic induction.
