In the situation described in the figure, the polarity of the capacitor is
A) B positive with respect to A B) A positive with respect to B
C) No charge on A and B D) A negative with respect to B
Viewing from RHS , The magnet’s south pole is approaching . By Lenz’s Law , this has to be opposed . This is done by inducing a south pole in the loop (looking from RHS) , because we know South repels South .
A south pole induced means a clockwise current is flowing through the loop . Therefore A will be at higher potential than B , OPTION B : A positive with respect to B
