Chapter 8, Problem 8.37P

A Toroid has known, reluctance R. Two windings having N1 and N2 turns are present. Find (a) the self-inductances of the two coils; (b) the mutual inductance between the coils.

A steady current of 3.5 A is flowing through an inductor with 50 volts across it. Find (a) Inductance of the coil if the current falls to zero in 120 msec, (b) Energy stored in the inductor, (c) Number of turns in the inductor for a flux of 40 mWb. adows bu bolow and find the value of current flowind
For a motor design, you need to design a solenoid coil that produces a magnetic flux density  (B) of at least 2000 gauss when a 10 mA current flows through the conductor. Due to space  limitations, the coil only can be 10 turns over a 1 cm length. To obtain the needed performance, go to Table 3 and choose a core material for the coil.
In short explain the dependency of the energy storage in the inductor on the dimension and the flux density. OR In short state the relation between the inductor energy and the dimension of condcutor and their flux density. Both are same question.
