A metal loop is placed in a perpendicular magnetic field as sketched in Figure P21.16.
(a) We wish to find the induced current through the loop. What closed path and which corresponding area should we choose for the application of Faraday’s law?
(b) What is the direction of the magnetic flux through the area chosen in part (a)? That is, is the flux upward (out of the plane of the figure) or downward (into the plane)?
(c) If the magnitude of B is increasing with time, is this flux increasing or decreasing with time?
(d) What is the direction of the magnetic field produced by the induced current?
(e) Will the induced current in the loop be clockwise or counterclockwise?
