Question

The rectangular loop of wire is being moved to the right at constant velocity. A constant current I flows in the long straight wire in the direction shown. The current induced in the loop is clockwise and proportional to I. counterclockwise and proportional to I. clockwise and proportional to I2. counterclockwise and proportional to I2. zero.

Explanation / Answer

1) zero :::

becuase movement of loop is parallel to the current direction , hence flux through loop is not changing with time , induced emf is zero ::: that is induced current is zero.

2)   clockwise propotional to i

loop is moving far away form the current , therefore magnetic filed produced by the current is decreases as the loop moves away from current source , hence flux decreses as time passes ,

so induced emf in clockwise direction .

current dircetion is clokwise.
