Question

The following setup has N = 1000 (uniformly wound all around the iron core (linear, µr = 1000) but not shown forclarity) turns and is powered by a sinusoidal current (where I(t = 0) = 0) of amplitude 10 A and frequency 60 Hz. Theloop measures 10 mm × 10 mm and rotates at 5000 rpm, and at t = 0 its surface plane normal is vertical. Assume B inthe gap is uniform (no fringing) and perpendicular to the iron surfaces. [3 marks](a) (1 mark) Find B in the gap.(b) (2 marks) Calculate the emf of the loop.​
