Magnetic field due to currentEasy
Question
A current I flow along the length of an infinitely long, straight, thin-walled pipe. Then
Options
A.the magnetic field at all points inside the pipe is the same, but not zero
B.the magnetic field at any point innside the pipe is zero
C.the magnetic fieldis zero only on the axis of the pipe
D.the magnetic field is different at different points inside the pipe
Solution
Using Ampere′s circuital law of 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.
