Question

why is it that for a hollow pipe magnetic field produced inside the pipe is zero​

Answer 1

Explanation:

If a long hollow copper pipe carries a direct current, the magnetic field associated with the current will be. As the current inside the pipe is zero. Therefore the magnetic field associated with the current will be only outside the pipe.
