A solenoid of length 20 cm and diameter 4 cm is constructed with 400 turns of wire The resistance of the wire can be neglected. A currenti is supplied to the solenoid in such a wav tha increases from zero to 0.5 A at a uniform rate over 2 seconds. Th 0.5 A. Calculate: e current then stays constant at (a) the inductance of the solenoid, (b) the maximum magnetic field in the solenoid, (c) the potential difference across the solenoid during the time when the current is increasing, (d) the potential difference across the solenoid during the time when the current remains constant, (e) the emf induced in a single circular loop of wire during the time when the current is increasing. Assume the loop has diameter 10 cm and is placed around the solenoid in such a way that the axis of the loop coincides with the axis of the solenoid
