A conductor is moved in a varying magnetic field. Name the law which determines the direction of current induced in the conductor.

Solution:

The Fleming’s right hand rule can be used to calculate the direction of current induced in a conductor when it is moved in a fluctuating magnetic field.
When a conductor moves in a magnetic field, Fleming’s right-hand rule illustrates the direction of induced current. The thumb, first finger, and second finger on the right hand are all perpendicular to each other (at right angles).
The conductor’s direction of motion is represented by the thumb. The first finger represents the Field’s direction (north to south). The direction of the induced or generated current is shown by the second finger. The direction of the induced current will be the direction of conventional current; from positive to negative.
