###### Question details

An infinitely long straight wire carries a current
** I,** and is bent at the angle

*. Find the magnetic field of the wire on the line AB. Then find the magnetic field on the line perpendicular to the plane of symmetry (line perpendicular to page) which passes through the point O. In both cases, find the magnetic field as functions of the distance*

**α****from the point O. Sketch a plot of magnetic field lines in the plane of symmetry.**
