a. State Faraday’s law of electromagnetic induction.

b. A circular coil of diameter 200 mm has 600 turns is shown. It is placed with its plane perpendicular to a horizontal magnetic field of uniform flux density 50 mT. The coil is then rotated through 90° about a vertical axis in a time of 120 ms.

Calculate:
i. The magnetic flux passing through the coil before the rotation
ii. The change of magnetic flux linkage produced by the rotation
iii. The average magnitude of the induced e.m.f. in the coil during the rotation.
