Energy stored in a magnetic field
Consider a circuit consisting of a voltage supply, switch, resistor and a coil of N turns wound on a toroid of length l, all in series.
With the switch open, no current flows inthe coil and therefore there is no flux produced in the core of the coil.
At t=0, the switch is closed and the current builds up with time. It is not instantaneous,because the coil produces a back emf that limits the rate of rise of current
where v = the time dependent back emf created by the coil. The instantaneous power being deliveredby the supply at time t is
vs .i=i2 R+v.i
Theoretical Circuit The theoretical circuit is available in form 1.Passive materials with mediocre dimension is used by the manufacturer. In order to make a theoretical circuit
Consider the magnetic circuit of Figure with an air gap, while neglecting leakage flux. Correct for fringing by adding the length of the air gap l g = 0.1 mm to each of the other
