1) An electric field E points toward you, and its magnitude is increasing. Will the induced magnetic field be clockwise or counterclockwise? What if E points away from you and is decreasing?

2) The electric field in an EM wave traveling east oscillates in a north-south plane. Describe the direction of the magnetic field vector in this wave.

Step 1

1. Maxwell’s right hand rule states that if the thumb points in the direction of the current then the curl of the fingers represent the direction of the magnetic field.

Step 2

If the electric filed points towards you and its magnitude is increasing, the direction of the displacement current due to the changing flux is towards you. Using Maxwell’s right hand rule, the direction of the magneti...
