A metallic plate is in the plane of this paper. A uniform magnetic field is perpendicular to the plane of the paper and creates a magnetic flux in the plate. Give the direction of the eddy currents in the plate (clockwise, counter-clockwise, or zero) for each of the following cases. Assume you are looking down onto the paper’s plane.
(a) The field points away from you and is decreasing.
(b) The field points toward you and is increasing.
(c) The field points toward you and is decreasing.
(d) The field points away from you and does not change with time.
