A rectangular coil of sides 8.50 cm and 17.5 cm contains 150 loops and its plane is positioned perpendicular to a uniform 0.40-T magnetic field, as shown. It is quickly and uniformly pulled from the field to a region where the B-field drops abruptly to zero. It takes 0.20 s for the whole coil to reach the field-free region. How much power is dissipated in the coil if its resistance is 110 Ω? ANS:______ W ズ ×
6. A circular coil of radius 6.50 em contains 150 loops and its plane is positioned perpendicular to a uniform 0.42-T magnetic field, as shown. It is quickly and uniformly pulled from the field to a region where the B-field drops abruptly to zero. It takes 0.18 s for the whole coil to reach the field.free region How much power is dissipated in the coil if its resistance is 1700? X X X X XXXX XXX
