If a long hollow copper pipe carries a current, then magnetic field is produced

A

inside the pipe only

B

outside the pipe only

C

both inside and outside the pipe

D

no where

Text Solution

Verified by Experts

The correct Answer is:
B
Inside the hollow pipe. magnetic field is zero, according to Ampere’s Law. So, the field is produced outside the pipe only.
