Electromagnetic Induction · Induction laws

When a coil is placed in a time dependent magnetic field the power dissipated in it is PP. The number of turns, area of the coil and radius of the coil wire are NN, AA and rr respectively. For a second coil's number of turns, area of the coil and radius of the coil wire are 2N2N, 2A2A and 3r3r respectively. When the first coil is replaced with second coil the power dissipated in it is 2 αP\sqrt2\,\alpha P. The value of α\alpha is .
