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 :

x>y

x < y \; \text{. }\;

[

x

and

y

are magnitudes of deflection.]

Solution:

x < y \; \text{. }\;

The emf induced across coil B will be more than coil A, as it has more number of turns. Thus higher induced current through the coil B will produce greater deflection in its galvanometer.
