Question

Define coefficients of coupling between two circuits. Derive an expression of energy stored in magnetic field

Answer 1

Answer:

The fraction of magnetic flux produced by the current in one coil that links with the other coil is called the coefficient of coupling between the two coils. k=1, when the flux produced by one coil, completely links with the other coil and is called magnetically tightly coupled. ...

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 .
