Question

You

You've seen how a charged object that is moving through a magnetic field will feel a force. If a metal rod is moved through magnetic field, the charged particles will feel a force, and if there is a complete circuit, a current will flow. We talk about the induced emf of the rod. The rod essentially acts like a battery, and the induced emf is the voltage of the battery. A magnetic field with a strength of 0.742 T is pointing into the page and a metal rod L=0.545 m in length is moved to the right at a speed v of 15.4m/s. What is the induced emf in the rod?

Explanation / Answer

Induced voltage is given as 15.4x0.742x0.545 = 6.227 V.

Magnitude of current is 6.227/3.26 = 1.91 A

Direction of current is counter clockwise
