All four wires are perpendicular to the plane of the page and have the same magnitude of current I. The conventional current in the wire in the upper right-hand corner is directed into the plane of the page. The other conventional currents are out of the plane of the page. Point P is a distance a from all four wires. Wha0a brrxw )56faa;wd1 pt is the total magnetic field at point P?
