A power line carries a 500-A current towards magnetic north and is suspended 10 m above the ground. The horizontal component of earth’s magnetic field at the power line’s latitude is 24 T. If a magnetic compass is placed on the ground directly below the power line which direction will it point? In this question, I understand why how to use both of the equations but could you explain why the direction is 22.62 degrees west of north in detail?
