Two circular coils $P$ and $Q$ are kept close to each other, of which coil $P$ carries a current. If coil $P$ is moved towards $Q$ , will some current be induced in coil $Q$ ? Give the reason for your answer and name the phenomenon involved.

Q. Two identical circular loops,

P

and

Q

, each of radius

r

and carrying equal currents are kept in the parallel planes having a common axis passing through

O

. The direction of current in

P

is clockwise and in

Q

is anti-clockwise as seen from

O

which is equidistant from the loops

P

and

Q

. Find the magnitude of the net magnetic field at

O

Two identical coaxial coils P and Q carrying equal amount of current in the same direction are brought nearer. The current in

The correct option is A Both P and Q decreasesTwo identical coaxial coils P and Q carrying equal amount of current in the same direction are brought nearer. The current in both P and Q decreases as per Lenz's law.
