Question

State Fleming's left-hand rule. Explain it with the help of labeled diagrams.

Answer 1

Fleming’s left-hand rule: Hold the forefinger, the centre finger and the thumb of your left hand to right angles to one other. Adjust your hand in such a way that the forefinger points in the direction of magnetic field and the centre finger points in the direction of current, then the direction in which thumb points, gives the direction of the force acting on the conductor.
