A magnet kept at the centre of two coils...

A magnet kept at the centre of two coils A and B is moved to and fro as shown in the diagram. The two galvanometers show deflection.

State with a reason whether :
`xgty`
or `xlty`. [x and y are magnitudes of deflection]

Text Solution

Verified by Experts

`xlty` because coil B has more number of turns hence there will be a greater change in magnetic flux linked with the coil B.
