Solution
The correct option is A The magnetic flux linked with the coil
Faraday's Law states that,
E=−Ndϕdt
Therefore, it depends only on the number of turns and the rate of change of magnetic flux. It may happen that rate of change depends on the area of cross section but this is always not the case. Consider the example,
A coil is placed in a uniform magnetic field but its area is shrinking at some given rate. This also results in electromagnetic induction.
