Question:

An air-filled toroidal solenoid has 300 turns of wire, a mean radius of 12.0 cm, and a cross-sectional area of 4.00 cm2. If the current is 5.00 A, calculate:
(a) The magnetic field in the solenoid;
(b) The self-inductance of the solenoid;
(c) The energy stored in the magnetic field;
(d) The energy density in the magnetic field.
(e) Check your answer for part (d) by dividing your answer to part (c) by the volume of the solenoid.
