**Problem 27:** In Fig. 29-55, two long straight wires (shown in cross-section) carry the currents \(i_1 = 30.0 \, \text{mA}\) and \(i_2 = 40.0 \, \text{mA}\) directly out of the page. They are equal distances from the origin, where they set up a magnetic field \(\vec{B}\). To what value must current \(i_1\) be changed in order to rotate \(\vec{B}\) 20.0° clockwise? **Explanation of the Diagram:** The diagram is a coordinate plane with an x-axis and a y-axis. There are two points marked on the plane: - The point on the positive y-axis is labeled as \(i_1\). - The point on the positive x-axis is labeled as \(i_2\). These represent the cross-sections of two wires carrying currents out of the page. The problem involves adjusting the current \(i_1\) to alter the magnetic field's direction.
