The loop is initially horizontal, so it is perpendicular to the magnetic field.

Wire 1 carries 1.00 A of current downward along the line x = -8.00 m. Wire 2 carries 2.00 A of current upward along the line x = 0. Wire 3 carries 3.00 A downward along the line x = 5.00 m. a) Find the magnetic field at (-5.00 m, 0). ________________________ If a charged particle moves near these wires, its trajectory will be complicated, not a simple line, circle, or helix because the magnetic field in this region is not uniform. However, if we look at just the initial trajectory over a short time interval, before the particle has moved a significant distance, we can approximate the field as uniform. Let’s do that. b) If a -4.00 µC particle is moving with a velocity of 14.0 m/s out of the page when it is at (-5.00 m, 0), what is the force on the particle?

If point A is the midpoint of the distance between the wires, point C is d/2 to the right of the wire carrying 10 A current. The distance d is given as 18 cm.
