Question

A conductor is moving with the velocity v in the magnetic field and induced current is I. If the velocity of conductor becomes double, the induced current will be

• A. 0.5 $I$
• B. 1.5 $I$
• C. 2 $I$
• D. 2.5 $I$

Answer 1

The correct option is C 2 $I$

When the conductor starts moving at double of its speed, it will cover double the initial distance throughout the field. Since the distance covered by the conductor is doubled, it will swap the double area in the same time throughout the field.

Since the area swapped is doubled, the induced current in the conductor will also be doubled.
