What is the current in the rod

Reference no: EM13975555

The figure shows a rod of length L caused to move at constant speed v along horizontal conducting rails. In this case the magnetic field in which the rod moves is not uniform but is provided by a current i in a long wire parallel to the rails. Assume that v = 4.50 m/s, a = 10.00 mm, L = 16 cm and i = 100 A. The rod has a resistance of 0.550Ω and the rails and connectors have negligible resistance.

What emf is generated?

What is the current in the rod?

At what rate is energy being tranferred to thermal energy in the rod?

What force must be applied to the rod by an external agent to maintain its motion?

At what rate does this external agent do work on the rod?
