A long solenoid (cross sectional area = 1.0 X 10-6 m2, number ofturns per unit length = 2400 turns/m) is bent into a circular shapeso it looks like a doughnut. This wire wound doughnut is called atoroid. Assume that the diameter of the solenoid is small comparedto the radius of the toroid, which is 0.50 m. With this assumption,use the results off example 13 to determine the self inductance ofthe toroid.

A toroid has a major radius and a minor radius and is tightly wound with turns of wire on a hollow cardboard torus. The figure shows half of this toroid, allowing us to see its cross-section. If , the magnetic field in the region enclosed by the wire is essentially the same as the magnetic field of a solenoid that has been bent into a large circle of radius . Modeling the field as the uniform field of a long solenoid, show that the inductance of such a toroid is approximately

 

An air-filled toroidal solenoid has 300 turns of wire, a mean radius of 12.0 cm, and a cross-sectional area of 4 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.
