Questions
A current I flows along the length of an infinitely long, straight and thin-walled pipe. Then
a
The magnetic field at all points inside the pipe is the same but not zero
b
The magnetic field at any point inside the pipe is zero
c
The magnetic field is zero only on the axis of the pipe
d
The magnetic field is different at different points inside the pipe
detailed solution
Correct option is B
Applying Ampere's law, ∮B. dl = μ0i to any closed path inside the pipe we find no current is enclosed. Hence, B = 0.Talk to our academic expert!
