Which of the following correctly describes the magnetic field near a long straight wire?

A

The field consists of straight lines perpendicular to the wire.

B

The field consists of straight lines parallel to the wire.

C

The field consists of radial lines originating from the wire.

D

The field consists of concentric circles centred on the wire.

Text Solution

Verified by Experts

The magnetic field lines near a long straight wire carrying current are concentric circles centred on the wire. So, choice (d) is correct.
