A 117-turn square coil of side 20.0 cm rotates about a vertical axis at ω = 1.59  103 rev/min as indicated in the figure below. The horizontal component of Earth's magnetic field at the coil's location is equal to

2.00 x10-5 T.

(a) Calculate the maximum emf induced in the coil by this field.

Step 1

Given:

Number of turns = 117

Area of coil = (0.2)2 m2

Angular frequency = 1.59 X 103 rev/min

Magnetic field, B = 2.00 x10-5 T.

Step 2

Part (a): The maximum emf induced in the coil

Step 3

Part (b): for maximum emf

Plane of coil must ...
