A conducting square loop of side l and resistance R moves in its own plane with uniform velocity v perpendicular to one of its sides. A magnetic field H, constant in time and and space pointing perpendicular and into the plane of the loop every where. The current induced in the loop is :(a) H ⁄ v R anti-clockwise (b) H ⁄ v R clockwise(c) 2H ⁄ v R anti-clockwise (d) zero |
