Two concentric circular wire loops in the same plane each carry a current. The larger loop has a current of $7\mathrm{.}62$ A circulating clockwise and has a radius of $6\mathrm{.}90$ cm$.$ The smaller loop has a radius of $1\mathrm{.}49$ cm$.$

$$

$$

What is the magnitude of the current in the smaller loop if the total magnetic field at the center of the system is zero?
