A uniform rod...

Question

A uniform rod of length L mass M and carrying current I is kept on the top of an inclined plane of angle of inclination theta. There is a uniform magnetic field B acting perpendicular to the plane. The coefficient of friction of the surface of the incline plane is (mu). Find the maximum and minimum value of magnetic field B such that the rod is at rest. Given acceleration due to gravity is g.
