A 100 turn coil has a radius of 3.2 centimeter and a resistance of 25Ω.
(a) The coil is in a uniform magnetic field that is perpendicular to the plane of the coil. Find what rate of change of the magnetic field strength will induce a current of 3.6 A in the coil?
(b) Find what rate of change of the magnetic field strength is required if the magnetic field creates an angle of 20 degree with the normal to the plane of the coil?
