Q1. (a) A 1000 turn coil, carrying I A current is wound uniformly on material X having a mean circumference of l cm and cross sectional area of A cm2. If the number of turn is
reduced, state whether the magnetic field strength, flux density and the reluctance will also increase, decrease or remains the same.
