Задача 31556.

In the isolated ring conductor radius of 20 cm flowing current of 10 A. perpendicular to the plane of the ring are two long wires with a current strength of 10 A and 20 so that they relate to the ring at points lying on opposite ends of a diameter. Determine the induction in the center ring, when currents flow in equal and opposite directions.
