Question

The figures below show two different situations where a current may be induced in a loop according to Faraday's Law, with the direction given by Lenz' Law. The magnetic field is shown by the x's in Fig. 2 (Note that the B-field is not uniform in Fig. 2). (The compass directions arc defined in the usual way. North is up, East is to the right etc.) Decide which statements correctly describe the induced current in one of the loops. If the first is T and the rest F, enter TFFFFF. fig1: Magnet moving East, induced current 'b'. fig2: Loop moving North, induced current 'b' fig1: Loop moving West, induced current 'b'. fig1: Magnet moving West, induced current 'b' fig2: Loop moving East, induced current 'b'. fig2: Loop moving South, induced current 'a'.
