# If the magnetic field is measured to have a strength of 242.25μT directed at an angle of 325°, what is the location of this measurement?

##
A wire carrying 969mA is travelling upwards along the Z axis through four different materials, one in each quadrant. The first quadrant is composed of cobalt; the second quadrant has iron, the third quadrant is made of nickel, and the 4th quadrant is air.
