Unformatted text preview: , and (c) the short circuit current. 4. A very long solenoid of radius a , carrying N turns per unit length, is looped by a circuit with resistance R , as shown below: (a) If the current in the solenoid is increasing at a constant rate, dI dt = k (a constant) what current ows in the circuit and which way (left or right) does it pass through the resistor? (b) If the current I in the solenoid is constant, but the solenoid is pulled completely out of the circuit loop and then reinserted in the opposite direction, what total charge passes through the resistor? 5.
