Question
Two straight parallel wires carry currents in opposite directions as shown in the figure. One of the wires carries a current of I2 = 11.5 A. Point A is the midpoint between the wires. The total distance between the wires is d = 12.6 cm. Point C is 4.07 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 magnitude of the magnetic field at point A.
What is the force between two 1.77 m long segments of the wires?
