The circuit shown in the figure is used to make a magnetic balance to weigh objects. The mass to be measured is hung from the center of the bar, which is in a uniform magnetic field of 1.50 directed into the plane of the figure. The battery voltage can be adjusted to vary the current in the circuit. The horizontal bar is 60.0 long and is made of extremely lightweight material, so its mass can be neglected. It is connected to the battery by thin vertical wires that can support no appreciable tension; all

Unformatted text preview: the weight of the mass is supported by the magnetic force on the bar. A 5.00 resistor is in series with the bar, and the resistance of the rest of the circuit is negligibly small. Which point, or , should be the positive terminal of the battery? Point should be the positive terminal of the battery....
