Question

A conductor hung horizontally in the north-south direction is connected to a galvanometer.the conductor is situated in a magnetic field acting in east-west direction.in whivh direction should you move the conductor if maximum current is to be induced in the conductor in the north south direction?.Justify your answer

Answer 1

For the maximum current from north to south the conductor should be moved in the south direction.

Explanation:

It is given in the question that the direction of the magnetic field is east west. So, when the conductor moves towards south then maximum flux change will occur. Now, according to Lenz’s Law, effect always opposes its cause. So, if the movement will be towards south then the current will be produced from south to north to oppose its cause.
