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.
