Question

A 117-turn square coll of side 20.0 cm rotates about a vertical axis at omega = 1.20 times 103 rev/min as indicated in the figure below. The horizontal component of Earth's magnetic field at the coll's location Is equal to 2.00 x 10-5 T. Calculate the maximum emf induced In the coll by this field. What Is the orientation of the coll with respect to the magnetic field when the maximum emf occurs? The plane of the coil Is perpendicular to the magnetic field. The plane of the coil Is parallel to the magnetic field. The plane of the coll Is oriented 45 degree with respect to the magnetic field.
