A magnetic field passing through two identical coils decreases from a magnitude

Question

A magnetic field passing through two identical coils decreases from a magnitude of Bex to zero in the time interval t. The first coil has twice the number of turns as the second.

Compare the emfs induced in the coils.??

How can you change the experiment so that the emfs produced in them are the same?

How can you change the experiment so that the emfs produced in them are the same?

Rotate the first coil such that the normal of the coil makes a 90 angle with respect to the external field. Rotate the first coil such that the normal of the coil makes a 30 angle with respect to the external field. Rotate the first coil such that the normal of the coil makes a 60 angle with respect to the external field. It is impossible.

Explanation / Answer

Answer) Rotate the first coil such that the normal of the coil makes a 60 angle with respect to the external field.

emfs produced are same when rate of change of fluxes are equal, emf = d(B.A) / dt
