A conducting rectangular loop moves with constant velocity v in the +x direction through a region of constant magnetic field B in the -z direction as shown.
- What is the direction of the induced current in the loop?
- The flux through this loop DOES change in time since the loop is moving from a region of higher magnetic field to a region of lower field.
- Therefore, by Lenz’ Law, an emf will be induced which will oppose the change of flux.
- The current i is induced in the clockwise direction to restore the flux.
- A conducting rectangular loop moves with constant velocity v in the -y direction and a constant current I flows in the +x direction as shown.
- What is the direction of the induced current in the loop?
