Practice covered

  1. When a conducting rod of length L moves with velocity v perpendicular to magnetic field B, the motional EMF induced is:
  2. A 0.40 m rod moves at 5.0 m/s perpendicular to a 0.60 T magnetic field. Calculate the induced EMF (in volts).
  3. A conducting rod slides on parallel rails in a magnetic field, forming a closed loop. If the rod moves with constant velocity, the induced current:
  4. Eddy currents are:
