What energy is stored in the inductor when the current in the circuit is 500 mA? b. At what rate is energy being stored in the inductor when I = 2.5 A? What power is being delivered to the circuit by the battery when I = 500 mA? d. Mr. Lewis decided to make an air- core solenoid with 108 turns, 8 cm long and has a diameter of 1.2 cm. How much energy is stored in its magnetic field when it carries a current of 100 Ma? C.
