a) what is the magnitude of the current needed to generate the force?

b) What direction of the current will cause the balance to register a positive mass reading?

7. (15 points) A 5.0 cm long copper wire resting on the plate of a pan balance (like in the lab) isplaced in a magnetic field produced by two permanent magnets as shown. The magnetic fieldPan Balancebetween the pole faces is 350 mT. The field is constant over the 1.5 cm wide pole face and dropsWireoff immediately outside the gap. The wire is connected to a power supply through two weightlesswires. The balance is tarred so that the weight of the copper wire is zeroed out when no current ispassing through the wire. The apparatus is shown viewed from above.Na)b)(10 points) What magnitude of current is needed to generate a force of 0.30 N?(5 points) What direction of current (a to b) or (b to a) will cause the balance to registera positive mass reading?S
