For problem 29.27 of the text, calculate the
current in wire 1 (in mA) needed to rotate the
magnetic field clockwise an angle of 29.5
degrees. 5 sig. figs.
Transcribed Image Text:27 In Fig. 29-55, two long straight
wires (shown in cross section) carry
the currents i₁ = 30.0 mA and i
40.0 mA directly out of the page.
They are equal distances from the
origin, where they set up a magnetic
field B. To what value must current i₁
be changed in order to rotate B 20.0°
clockwise?
