Physics EM Induction A-level Question
A coil with 20 circular turns each of diameter 60 mm is placed in a uniform magnetic field of flux density 90 mT.
Initially the plane of the coil is perpendicular to the magnetic field lines.
The coil is rotated about a vertical axis by 90° in a time of 0.20 s so that its plane becomes parallel to the field lines.
Assume that the rate of change of flux linkage remains constant.
What is the emf induced in the coil?

What have you tried? Or what is causing the issue?
Apply Faraday's law.
