A 10 cm length of wire with a mass of 20 g is attached frictionlessly to the vetical segments of a wire in which a current I flows. The surrounding has horizontal field B=104G and the vertical direction is shown in fig. What must be the current I (in A) to maintain the 10 cm wire in an equilibrium position?

A metal wire PQ of mass 10 g lies at rest on two horizontal metal rails separated by 5 cm as shown in Fig. A vertically downward magnetic field of magnitude 0.80 T exist in the space. The resistance of the circuit is slowly decreased and it is found that when the resistance goes below 20.0 Ω the wire PQ starts sliding on the rails. The coefficient of friction between wires and rails is found. The coefficient of friction between wires and rails is found to be n/25. find n

A current I = 10 A flows in a ring of radius r 0 = 15 cm made of a very thin wire. The tensile strength of the wire is equal to T=1.5N. The ring is placed in a magnetic field, which is perpendicular to the plane of the ring so that the forces tend to break the ring. Find B (in T) at which the ring is broken.
