Two concentric circular wire loops in the same plane each carry a current. The larger loop has a current of 8.62 A circulating clockwise and has a radius of 6.09 cm. The smaller loop has a radius of 4.42 cm. What is the current in the smaller loop if the total magnetic field at the center of the system is zero?
