Question

mention the expression for magnetic potential energy stored in an inductor when current flows through it​

Answer 1

Explanation:

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=B22μ u B = B 2 2 μ

uB=B22μ u B = B 2 2 μ .
