A long horizontal wire carries 22.0 of current due north.
Part A: What is the absolute value of the net magnetic field 25.0 due west of the wire if the Earth's field there points north but downward, 39 below the horizontal, and has magnitude 5.0 ?
Part B: What is the angle of the net magnetic field 25.0 due west of the wire if the Earth's field there points north but downward, 39 below the horizontal, and has magnitude 5.0 ?
