A metallic rod of mass per unit length $$0.5 kg m^{-1}$$ is lying horizontally on a smooth inclined plane which makes an angle of $$30^\circ$$ with the horizontal. The rod is not allowed to slide down by flowing a current through it when a magnetic field of induction 0:25 T is acting on it in the vertical direction. The current flowing in the rod to keep it stationary is
