A long wire, having current , is bent into the shape shown in the figure. Find the magnetic field at point . The lengths .
Text solutionVerified
Field due to segment 1 can be obtained by putting and in equation (5).
[One end of the wire is at , hence .
The other end goes to infinity. Therefore, ]
Field due to segment 3 is same as . The direction of the field is also same.
Field due to segment 2 (i.e., ) is
The direction of the field due to each segment is out of the plane of this figure. The three fields will add.
