Question

derive an expression of stored energy in magnetic fields interms of magnetic vector potential and magnetic fields​

Answer 1

Answer:

The formula for the energy stored in a magnetic field is E = 1/2 LI2.

The energy stored in a magnetic field is equal to the work needed to produce a current through the inductor.

Energy is stored in a magnetic field. Energy density can be written as

uB=B^2/2μ
