Suppose you wish to make a solenoid whose self-inductance is 1.4 mH. The inductor is to have a cross-sectional area of 1.2x10^-3 m^2 and length of .052 m and N = 220 turns of the wire. For current I = 6A being passed thru the inductor, calculate (a) magnetic field inside the coil, (b) energy stored within the coil and (c) energy density inside the coil.
