Answer:

Using Ampere's circuital law over a circular loop of any radius less than the radius of the pipe, we can see that net current inside the loop is zero.

Hence, magnetic field at every point inside the loop will be zero.

Then the magnetic field at any point inside the pipe is zero.

• Applying Ampere's law, d l = μ 0 I , to any closed path inside the pipe, we find no current is enclosed.
