An inductor of 170 turns has a radius of 8 cm and a length or 30 cm. The permeability of free space is 1.25664 x 10^-6 N/A^2.Find the energy stored in it when the current is 0.6 A.
Inductance of a solenoid, air L ??N?A/Ln Ln is length in meters A is area in meters? N is number of turns ?? is the magnetic constant 1.2566×10?6?H/m (or T·m/A) use the above formula to calculate inductance. Change units to meters. then use E ?LI? Energy in an inductor to get the energy. .
