A coll of 300 turns is wound uniformly on a ring of non-magnetic material. The ring has a mean circumference of 40 cm and a uniform cross sectional area of 4 cm2. If the current in the coll is 5 A, calculate (a) the magnetic field strength, (3) (b) the flux density and (c) the total magnetic flux in the ring (3) [10]
