Question

Energy stored in magnetic field is W=_____.
(a) 1/(2μo) surface Integration of B².dT
(b) 1/(2μo) surface Integration of B.dT
(c) 1/(2μo) surface Integration of E².dT
(d) 1/(2μo) surface Integration of E.dT
(T means torque)​

Answer 1

Answer:

The formula for the energy stored in amagnetic field is E = 1/2 LI2. Theenergy stored in a magnetic field is equal to the work needed to produce a current through the inductor. Energy isstored in a magnetic field. Energydensity can be written as uB=B22μ u B = B 2 2 μ .
