Part A The circuit shown in the figure is used to make a magnetic balance to weigh objects. The mass m to be measured is hung from the center of the bar, that is in a uniform magnetic feld of 1.50 T, directed into the plane of the figure. The battery voltage can be adjusted to vary the curent in the circut The horizontal bar is 600 cm long and is made of extremely light-weight material. Itis connected to the battery by thin vertical wires that can support no appreciable tension al he weight of the suspended mass m is supported by the magnetic force on the bar Aresistor with R500 1 is in senes with the bar, the resistance of the rest of the circuit is much less than this.
