The magnetic induction at any point due ...

The magnetic induction at any point due to a long straight wire carrying a current is

A

proportional to the distance from the wire

B

inversely proportional to the distance from wire

C

inversely proportional to the square of the distance from the wire

D

does not depend on distance

Text Solution

Verified by Experts

The correct Answer is:
B
For conductor of finite length magnetic field at any point carrying current I is, `B= (mu_(0)I)/(4pi r)(sin theta_(1) + sin theta_(2))`.
