Find the self-inductance of a toroidal solenoid of radius 20 cm, area of cross section 100 cm^(2) and having 500 turns. Assume that the field variations across the cross section of the toroid are negligible. Further, if a secondary coil of 300 turns is wound on this toroid and the current in the primary coil is increased from 2 A to 5 A in 0.05 s. Find the emf induced in the secondary coil.

What is the difference in the field of a toroid and a solenoid?
