Answer 2

First we need to know the required law:

Faraday's Law of Electromagnetic Induction states that the amount of of EMF induced will be directly proportional to the the rate of change of magnetic flux.

Higher the induced EMF , higher will be the deflection in the galvanometer.

$\boxed{ \bf{EMF = \dfrac{d( \phi)}{dt} = \dfrac{d(nBA)}{dt} }}$

So, deflection in the galvanometer will be increased in the following cases:

• Higher rate of change of magnetic flux.

• Higher number of coils (n)

• Higher value of magnetic field or area of magnetic flux in a specified time.

Hope It Helps.
