Points O, A, and P lie in one as well as the same vertical plane. Point A is 4.0 cm due east of point O starting at point O one is able to arrive at point P by going 6.0 cm due east and from there 3.0 cm straight upward (not northward, upward). At point A there is an infinitesimal wire section carrying current due east. What is the path of the infinitesimal magnetic field vector at point P produced by the current-carrying wire segment at point A?
