An induction coil of area 48,6 cm2 and 200 windings is rotated clockwise in a constant magnetic field of magnitude 2,4 T. Refer to the diagram below.
The graph below shows how the induced emf varies with the inverse of time.
9.1 State Faraday’s law in words. (2)
9.2 Use the information in the graph to calculate the change in magnetic flux. (5)
9.3 The coil rotates through an angle θ to a position where the magnetic flux becomes zero. Calculate angle θ. (4)
