Electricity and Magnetism Level 2

A horizontal conducting rod of mass \(m\) is free to slide on two vertical conducting rails as shown. The terminal speed of the rod is

Details and Assumptions:

  • Uniform magnetic field intensity \(B\) exist throughout the region and is normally inward.

  • Length of the rod is \(L\).

  • Resistance of the resistor is \(R\).

Bonus What will happen if the magnetic field is outward? Will the rod attain terminal velocity?
