b. (10) A toroidal current carrying winding is wound about an iron

b. (10) A toroidal current carrying winding is wound about an iron toroid with a small air gap. The length of the iron path is 50 cm and the gap is 1 mm. If the magnetic field in the iron is 1.5 T find (a) Bgap, (b) Hiron, (c) Hgap. Take r = 5000 for the iron and ignore leakage in the gap. Cut a small gap here AB B
