Consider a 34.5 cm-long wire with a radius of 0.035 mm, which is hung loosely in the air in a region where the magnetic field has a constant magnitude of 4.8 mT directed horizontally and perpendicular to the wire, as shown in the picture below. This wire is connected to (fully-supported) wires and a shunt resistor, totaling an additional 5.4 of resistance. The wire's material has a resistivity of 4.3 × 10-³. m and a density of 22.6 g/cm³. b ہے What voltage must be applied across points a and b in order to make the hanging wire levitate? Va-Vb= V
