Question

A square loop $PQRS$ is carried away from a current carrying long straight conducting wire $CD$. The direction of induced current in the loop will be

• A. anticlockwise
• B. clockwise
• C. sometimes clockwise some times antclockwise
• D. current will not be induced

Answer 1

The correct option is A anticlockwise

When a current carrying conductor, due to this magnetic field is created as per Oersted experiment. Due to this magnetic field flux lines are produced.these flux lines cuts square loop emf is induced The current induced in the square loop creates another field, in the opposite direction of the bar magnet’s to oppose the increase. As per Lenz’s law—induction opposes any change in flux.
