Sure, here are the step-by-step solutions:
Given:
Radius of coil,
Initial strength of magnetic field,
Final strength of magnetic field,
Area of coil,
Initial flux through the coil,
= 6.28 Wb
Final flux through the coil,
= 2.51 Wb
Time taken by flux to change from to , t= 5 s
Number of turns, N = 50
