Question

Two straight parallel wires carry currents in opposite directions as shown in the figure. One of the wires carries a current of $I_2 = 12.0$ A. Point A is the midpoint between the wires. The total distance between the wires is $d = 12.1$ cm. Point C is 4.95 cm to the right of the wire carrying current $I_2$. Current $I_1$ is adjusted so that the magnetic field at C is zero. Calculate the value of the current $I_1$. Calculate the magnitude of the magnetic field at point A. What is the force between two 2.05 m long segments of the wires?

Step 1

0\) A $d = 12.1$ cm = 0.121 m Point C is 4.95 cm = 0.0495 m to the right of the wire carrying current $I_2$ Using the magnetic field formula at point C: $B_{\text{net}} = \frac{\mu_0 I_1}{2\pi d} - \frac{\mu_0 I_2}{2\pi (d/2)}$ Substitute the given values Show more…
