A current I flows through an infinitely long, straight copper walled pipe. Then: |
The magnetic field at all points inside the pipe is same, but not zero The magnetic field is zero only on the axis The magnetic field is different at different points inside the pipe The magnetic field at any point inside the pipe is zero |
The magnetic field at any point inside the pipe is zero |
The correct answer is Option (4) → The magnetic field at any point inside the pipe is zero |
