A coil of 1000 turns is wound on a ring of silicon steel, having a mean diameter of 10 Cm and relative permeability of 1200. Its cross sectional area is 12 Sq.Cm. When a current of 5A flows through the coil, find flux in the core, the inductance of the coil and the induced emf, if the flux falls to zero in 20 mS A coil of 1000 turns is wound on a ring of silicon steel, having a mean diameter of 10 Cm and relative permeability of 1200. Its cross sectional area is 12 Sq.Cm. When a current of 5A flows through the coil, find flux in the core, the inductance of the coil and the induced emf, if the flux falls to zero in 20 mS
