Figure (a) shows a rod PQ of length 20 cm and mass 200 g suspended through a fixed point O by two threads of lengths 20 cm each. A magnetic field of strength 0.500 T exists in the vicinity of the wire PQ as shown A metal wire PQ of mass 10 g lies at rest on two horizontal metal rails separated by 5 cm. A vertically downward magnetic field of magnitude 0.800 T exists in the space.
