Two straight parallel wires carry currents in opposite
directions as shown in the figure. One of the wires carries a
current of I2 = 10.2 A. Point A is the midpoint between
the wires. The total distance between the wires is d = 12.1 cm.
Point C is 5.03 cm to the right of the wire carrying current
I2. Current I1 is adjusted so that the
magnetic field at C is zero. Calculate the value of the current
I1.Calculate the...
