Answer:
<h3>The area of second coil is ≅ 0.025Explanation:
Given :
No. of turns in the first coil
No. of turns in the second coil
Area of first coil
According to the law of electromagnetic induction,
Induced emf =
Where magnetic flux.
Since given in question emf of both coil is same so we compare above equation.
Therefore, the area of second coil is ≅ 0.025
