In the magnetic circuit shown in Figure (a) the coil of 500 turns carries a current of 4 A. The air-gap lengths are g1 = g2 = 0.25 cm and g3 = 0.4 cm. The cross-sectional areas are related such that A1 = A2 = 0.5A3. The permeability of iron may be assumed to be infinite. Determine the flux densities B1, B2, and B3 in the gaps g1, g2, and g3, respectively. Neglect leakage and fringing.
Explain Eddy currents. Eddy currents: Magnetic materials placed as in alternating magnetic fields have eddy currents also induced in them. It is because the material is subject
