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<sup>-5</sup> 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. A) 3.0*0<sup>-4</sup> V B) 1.2 *10<sup>-5</sup> V C) 1.0 * 10<sup>-4</sup> V D) 3.8 *10<sup>-4</sup> V E) 2.4* 10<sup>-4</sup> V A 0.8-m-long pole rotates about a perpendicular axis at one end.
