A long horizontal wire carries a 12.0 A of current due north. What is the net magnetic field 20.0 CM due west of the wire if the Earth's field there points downward 40 degrees below the horizontal, and has a magnitude of 5.0x10^-5
Unsure on how to start...Do you find the magnetic field produced by the wire and combine it with the Earth's? If so, I did that and found the field produced by the wire to be 1.2 x 10^-5, so how do you combine fields.
