An induction coil of area 48,6 cm^2 and 200 windings is rotated clockwise in a constant magnetic field of magnitude 2,4 T.

1. Use the information in the graph to calculate the change in magnetic flux.
2. The coil rotates through an angle θ to a position where the magnetic flux becomes zero. Calculate angle θ.

The gradient of that graph is =  of windings x change in flux

Gradient = 3.4-1.6/2-1

= 1.8

1.8=200 x change in flux

change in flux= 0.009Wb

flux = BAcosθ

0=(2.4)(48.6/10000)cosθ

θ=90
