A 08-M-Long Pole Rotates About a Perpendicular Axis at One End

question 82

Multiple Choice

A 0.8-m-long pole rotates about a perpendicular axis at one end. As the pole rotates, it passes through Earth's magnetic field, which has a perpendicular component of 3 *10^-5 T to the plane of rotation. If the pole rotates with a frequency of 5 revolutions per second, calculate the induced EMF across the ends of the pole.
