The figure below shows two current-carrying loops with I1 = 4.40 A clockwise and I2 = 8.60 A counterclockwise, placed with their centers at the origin of the xy plane. (a) If r1 = 12.5 cm and r2 = 18.5 cm, what are the magnitude and direction of the magnetic field due to the two loops at the origin? magnitude T direction (b) If r1 is held constant at 12.5 cm, what would r2 have to be for the magnetic field at the origin to be 0? cm
