Chapter 5.2, Problem 5CQ
Two infinitely long parallel wires carry currents of equal magnitude. What is the resultant magnetic field due to the two wires at a point midway between the wires, compared with the magnetic field due to one of them alone, if the currents are (a) in the same direction and (b) in opposite directions?

Question Three: Magnetic Force between wires.
Three long parallel wires are 5 cm from one another. (Looking along them, they are at three
corners of an equilateral triangle.) The current in each wire is 10.00 A, but its direction in wire M
is opposite to that in wires N and P. Determine the magnetic force per unit length on each wire
due to the other two.

Two parallel straight wires are separated by a distance of 0.12 m and carry currents of I1 = 3.0 A and I2= 1.4 A. What is the magnitude and direction of the force that the magnetic field of wire 2 applies to a 1.2-m length of wire 1 when the currents are in opposite direction?
A single straight wire produces a B-field. Another wire is parallel and carries an identical current. If the two currents are in the same direction, how would the magnetic field be affected? What if the currents are in the opposite direction?
