Problem 1:
Two long thin parallel wires are 0.1 m apart and each wire carries a current of 12 A. The current
for the wire on the left is into the page and the current for the wire on the right is out of the
page. What is B at point P, 0.08 m from one wire and 0.06 m from the other wire?
Hint: Point P is on the corner of the right triangle with the right angle.

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)?
