Question
A current I flows along the length of an infinitely long, straight, thin walled pipe. Then
-
the magnetic field is zero only on the axis of the pipe
-
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 all points inside the pipe is the same, but not zero
Solution
C.
the magnetic field at any point inside the pipe is zero
