A circular loop of wire and a long, straight wire carry currents of I1 and I2 (see the drawing), where I2 = 4.9I1. The loop and the straight wire lie in the same plane. The net magnetic field at the center of the loop is zero. Find the distance H, expressing your answer in terms of R, the radius of the loop.(adsbygoogle = window.adsbygoogle || []).push({});
