Question
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 or x< y [x and y are magnitudes of deflection.]
Solution
∴ The number of turns in B is greater than in A.
∴ Deflection in B will be greater than deflection in A i.e. y > x.
