The magnetic field in the cylindrical region shown in figure increases at a constant rate of `20.0mT//sec` . Each side of the square loop abcd and defa has a length of `I.00cm` and a resistance of `4.00Omega` . Find the cuurent (magnitude and sense) in the wire ad if:  (a) the switch `S_(I)` is closed but `S_(2)` is open (b) `S_(I)` is but `S_(2)` is closed  (c) both `S_(I)` and `S_(2)` are open and  (d) both `S_(I)` and `S_(2)` are closed
