The two concentric circular loops of equal radii cm carry currents and respectively. Loop one is in the vertical plane, current I1 is clockwise.

The two concentric circular loops of equal radii cm carry currents and respectively. Loop one is in the vertical plane, current I1 is clockwise. Loop 2 is in the horizontal plane, and the current I2 is counterclockwise as seen from above. Find the net magnetic field at the center of the loop.
