Two pieces of the same wire have the same length. From one piece, asquare coil containing a single loop is made. From the other, acircular coil containing a single loop is made. The coils carry different currents. When placed in the same magnetic field with the same orientation, they experience the same torque. What is the ratio Isquare / Icircle of the current in the square coil to the current in the circular coil?
