A flat conducting plate is centered in the \(x y\) plane of an \(x y z\) coordinate system in which the \(x y\) plane is horizontal. A bar magnet is lowered vertically toward the plate. If the magnet is oriented so that its north pole faces the origin as the magnet moves toward the plate, what do the electric field lines in the plate look like? What do the field lines look like if the south pole faces the origin as the magnet moves?
