A wire with the current Io = 4 A flowing out of the page is placed next to a ring carrying current I = 0.5 A, which is perpendicular to the plane, as shown. The distance between the wire and the center of the loop is d = 1 cm, and the radius of the ring is R = 7 mm. lo wire a) What is the magnitude of the torque that the wire exerts on the loop? Give your answer in Nm without units. Use exponential notations (for example, enter 5 x 10-5 as 5e-5). N.m b) What is the equilibrium orientation of the loop? Frontal (a 90° turn about the vertical axis). d Vertical, as now in the figure. In the horizontal plane (a 90° turn about the axis going into the page). R
