Two infinitely long parallel conductors carrying currents are directed at right angles to the plane of the drawing. The maximum of magnetic induction is at a point M that lies in the middle between the conductors. The direction of the magnetic induction vector B at this point coincides with the positive direction on the x axis. Determine the direction of the currents flowing in the conductors and the relationship that exists between these currents.

Two infinitely long parallel cond uctors carrying currents are directed at right angles to the plane of the drawing. The magnetic induction at a point M that lies in the middle between the conductors is zero. To the right of this point, the magnetic induction vector points upward, at right angles to the x axis. Find the direction of the currents flowing in the conductors, the direction of the magnetic induction vector to the left of point M, the relationship between the currents, and the point on the x axis at which the magnetic induction is maximal. The distance between the conductors is a.
