proposed energy storage

A proposed energy storage mechanism consists of an N-turn coil wound around a large nonmagnetic (µO = µ toroidal form as shown in Fig. 1.30. As can be seen from the figure, the toroidal form has a circular cross section of radius a and toroidal radius r, measured to the center of the cross section. The geometry of this device is such that the magnetic field can be considered to be zero everywhere outside the toroid. Under the assumption that a

For a coil with N = 1000 turns, r = 10 m, and a = 0.45 m

 the coil inductance L.

b. The coil is to be charged to a magnetic flux density of 1.75 T. Calculate the total stored magnetic energy in the toms when this flux density is achieved.

c. If the coil is to be charged at a uniform rate (i.e., di/dt = constant), calculate the terminal voltage required to achieve the required flux density in 30 sec. Assume the coil resistance to be negligible.
