An iron-cored choke is designed to have an inductance of 20 H when operating at a flux density 1 T, the corresponding relative permeability of iron core is 4000. Determine the number of turns in the winding, given that the magnetic flux path has a mean length of 22 cm in the iron core and 1 mm in air-gap that its cross-section is 10cm2.
