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

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...

In the figure below a thin coil of radius r1= 4 cm, containing
N1= 5300 turns, is connected through a resistor R = 100 Ω to an AC
power supply running at a frequency f= 2100 so that the current
through the resistor (and coil) is I1sin(2π×2100t). The voltage
across the resistor triggers an oscilloscope that also displays
this voltage, which is 10 V peak-to-peak and therefore has an
amplitude of 5 V (and therefore the amplitude of the current...
