Consider a magnet surround by a wire with an on`//` of switch `S` (figure) if the switch is thrown from the off position (open circuit) to the on position the (closed circuit). A. The current will flow in `C.W` direction as seen from the left sideB. the current will flow in anti clock wise direction as seen from `L.H.S`C. The current will not flowD. Can not be decided. |

Answer» Correct Answer - C When the switch is thrown the off position (open circuit) to the position (closed circuit) then neither `B`, nor `A` the angle between `B` and `A` change thus no change in magnetic flux linked with coil occur, hence no electromotive force is produced and consequency no current will flow in the circuit. |
