Задача 31121.

Two circular turns with current lie in the same plane and have a common center. The radius of the large turn is 12 cm, the smaller one is 8 cm. The field strength at the center of the turns is 50 A/m if the currents flow in one direction, and zero if in the opposite direction. Determine the strength of the currents flowing along the circular turns.
