A high-voltage power line carries a current of 101 A at a location where the Earth's magnetic field has a magnitude of 0.588 G and points to the north, 71.9° below the horizontal. Calculate the magnitude of the magnetic force exerted on a 259 m length of wire if the current in the wire flows horizontally toward the east.
Calculate the magnitude of the magnetic force exerted on a 259 m length of wire if the current in the wire flows horizontally toward the south.
