The two coils A and B wound coaxially on an insulating cylinder. It will be evident that the fluxes produced by a current i through the two coils are in the same direction, and the coils are said to be cumulatively coupled. If the direction of the current in B relative to that in A is reverse, then coils are said to be differential coupling. Suppose A and B to have self- inductances LA and LB henrys respectively and a...

Helmholtz coils are two circular coils with radius R, each wound with N turns of wire carrying a current I, circulating in the same direction in both coils. The coils are placed distance R apart. The Helmholtz coil produce a very uniform magnetic field in the region between them. Obtain an expression for the magnitude of the magnetic field at point P, which is midway between the coils.

Two air-cored coils are disposed relatively to each other so that 60% of the flux in one coil links all the turns of the other coil. Each coil has a mean diameter of 2cm and a length of 50 cm. If there are 2000 turns of wire on one coil, calculate the number of turns required on the other coil to give a mutual inductance of 20 mH
