Task id256

Two infinitely long straight conductors located at a distance of 50 cm from each other carry currents I1 and I2 with a force of 5 A each in the same direction. Between the conductors at a distance of 30 cm from the first there is a ring conductor, the current strength of which I3 is 5 A ( Fig. 31). The radius of the ring is 20 cm. Determine the induction and strength of the magnetic field created by the currents in the center of the ring conductor.
