A current balance is constructed as follows: part of a wire, 10.0 cm long, is placed on a plate of an electronic balance, as shown in the figure below. This wire is connected to a current source (power supply) and a long horizontal wire, parallel to the wire on the platter, positioned just above it. The distance between the central axis of the two wires is 2.00 cm. When the source is turned on, the scale reading increases by 7.00 mg. What is the current in the wire (at A)? If the sensitivity of the balance is 0.100 mg, what is the minimum current that can be detected (in mA to one decimal place)?
