A high-voltage power line carries a current of 124 at a location where the Earth's magnetic field has a magnitude of 0.59 G and points to the north, 65 degrees below the horizontal.
A) Find the magnitude of the magnetic force exerted on a 330 length of wire if the current in the wire flows horizontally toward the east.
B) What direction does the magnetic force point?
C) Find the magnitude of the magnetic force exerted on a 330 length of wire if the current in the wire flows horizontally toward the south.
