A solenoid has a radius of 3.5 cm, 160 turns and a length of 1.2 m. Take the solenoid to have negligible (zero) resistance. The terminals of the solenoid are connected across a 15 Ω resistor at time zero and the circuit is given an initial current of 55 mA.
a) How long will it take for the current to drop to 12mA?
b) At time zero, just after the current in the circuit is initiated, what is the energy stored in the solenoid and what is the voltage across the solenoid?
3. A solenoid has radius 5.80 mm, length 11.0 cm, 5000 turns, and is placed with its axis of symmetryalong the x-axis, through the origin.
