A rectangular loop of wire with dimensio...

A rectangular loop of wire with dimensions shown in figure is coplanar with a long wire carrying current `'I'`. The distance between the wire and the left side of the loop is `r`. The loop is pulled to the right as indicated. What are the directions of the induced current in the loop and the magnetic forces on the left and right sides of the loop when the loop is pulled ?

A

`{:("Induced current","Force on left side","Force om right side",,),("Counterclockwise","To the left","To the left",,):}`

B

`{:("Induced current","Force on left side","Force om right side",,),("Counterclockwise","To the right","To the left",,):}`

C

`{:("Induced current","Force on left side","Force om right side",,),("Clockwise","To the right","To the left",,):}`

D

`{:("Induced current","Force on left side","Force om right side",,),("Clockwise","To the left","To the right",,):}`

Text Solution

Verified by Experts

The correct Answer is:
D

As the flux decreases, tom maintain flux, current in the loop is clockwise. Force on `DA` due to the long wire is towards left while on `BC` is towards right.
