Question

Two current carrying coils P and Q are close to each other, of which coil P carries a current. If coil P move towards Q, will some current be induced in coil Q? give reason for your answer.

Answer 1

Answer:

yes current will induce in coil Q because of change in flux.

Explanation:

their would be magnetic field due to the current in coil P.

this flux will increase as it moves towards coil Q(w.r.t. coil Q). Hence lenz law will take place and a current will induced.

Answer 2

Two circular coil 'P' & 'Q' are placed closed to each other. If the current in the coil 'P' is changed, then will some current be induced in coil 'Q'. Explain.

Because of Electromagnetic Induction.

When the current change in 'P' then the magnetic field linked of the coil change as well.

Hence, the overall magnetic field around the coil 'Q' also change.
