5. You have a solenoid-shaped inductor.It is connected to a circuit with an alternating current supply. At a particular moment, the current in the circuit is 1.5 Amps and is decreasing by 0.4 Amps/sec. The inductor has a resistance of 3 Ohms. (20 points)

  1. (a) If the inductor stores 0.855 J of energy at this moment, what is its inductance?

  2. (b) What is the voltage difference measured across the inductor at this moment?

  3. (c) If the radius of the coils in the inductor is 0.5 cm, and the length of the inductor is 2.4 cm, what is the magnetic field inside the inductor and what is the energy density?

  4. (d) If a wire was wrapped around the solenoid 4 times and the wire has a resistance of 5 Ohms, what is the induced current in this second wire?
