In Fig. `29-57,` two long straight wires ( shown in cross section ) carry the currents `i_(1)=30.0` mA and `i_(2)=50.0` mA directly out of the page. They are equal distances from the origin, where they set up a ,magnetic field `vecB`. To what value must current `i_(1)` be changed in order to rotate `vecB25^(@)` clockwise ?

Text Solution

Figure 29-62 shows, in cross section, four thin wires that are parallel, straight, and very long. They carry identical currents in the directions indicated. Initially all four wires are at distance d=15.0 cm from the origin of the coordinate system, where they create a net magnetic field vecB . (a) To what value of x must you move wire 1 along the x axis in order to rotate vecB counterclockwise by 30^(@) ? (b) With wire 1 in that new position, to what value of x must you move wire 3 along the x axis to rotate vecB by 30^(@) back to its initial orientation ?
