Question

Magnetic field due to a current carrying infinitely long wire at a distance from the wire

Answer 1

Answer:

hey mate here is your answer:

The magnetic field lines of the infinite wire are circular and centered at the wire and they are identical in every plane perpendicular to the wire. Since the field decreases with distance from the wire, the spacing of the field lines must increase correspondingly with distance. The direction of this magnetic field may be found with a second form of the right-hand rule

thank you :)
