A 200-turn circular coil of area 100cm2 is rotated at a steady speed of 1500rpm about an axis perpendicular to a uniform magnetic field of magnitude 0.20T. The axis of rotation is such that the coil is edge-on to the field at t=0. Answer the following:
(i) Convert the rotational speed of the coil to angular speed in rad s−1.
(ii) Calculate the maximum (peak) value of the emf induced in the coil.
(iii) Determine the instantaneous emf at t=2.5ms after the coil passes the position where the magnetic flux through it is maximum.
