Question

shows an increasing magnetic field and the electric field that accompanies it according to Faraday's law. The magnetic field is increasing at an increasing rate. Is the electric field magnitude constant, increasing, or decreasing? decreasing increasing constant The magnitude of the electric field is proportional to the emf induced by the changing magnetic field, anc Does the behavior of the electric field produce an additional magnetic field? What is the direction of the additional magnetic field? The additional magnetic field is directed toward the right in the region of the original magnetic field. The additional magnetic field is directed into the figure in the region of the original magnetic field. The additional magnetic field is directed toward the left in the region of the original magnetic field. The additional magnetic field is directed out of the figure in the region of the original magnetic field. Does it reinforce or counteract the original magnetic field?

Explanation / Answer

C) Magnetic field by induced current opposes the external magnetic field. Thus induced magnetic field is opposite to the external magnetic field and thus directed to the left.

D)Counteract: Magnetic field by induced current opposes the external magnetic field.
