Thirty-seven turns of insulated wire 0.100 cm in diameter are tightly wound to form a flat spiral. The spiral fills a disk surrounding a circle of radius 5.00 cm and extending to a radius 8.70 cm at the outer edge. Assume the wire carries a current I at the center of its cross section. Approximate each turn of wire as a circle. Then a loop of current exists at radius 5.05 cm, another at 5.15 cm, and so on. Numerically...
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
