A square conducting loop is in a region of uniform, constant magnetic field. Can the loop be rotated about an axis along one side and no emf be induced in the loop? Discuss, in terms of the orientation of the rotation axis relative to the magnetic-field direction.
(II) In Fig. 21–11, the moving rod has a resistance of 0.25Ωand moves on rails 20.0 cm apart. The stationaryconductor has negligible resistance. When a force of 0.350 Nis applied to the rod, it moves to the right at a constantspeed of 1.50 m/s What is the magnetic field?
A circular coil of radius 4.00 cm contains 120 loops and its plane is positioned perpendicular to a uniform 0.74-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 0.12 s for the whole coil to reach the field-free region. How much power is dissipated in the coil if its resistance is 170 Ω?
