A high-voltage power line carries a current of 120A at a location where the Earth's magnetic field has a magnitude of 0.59 G and points to the north, 63 degrees below the horizontal.

Part A:Find the direction of the magnetic force exerted on a 290 m length of wire if the current in the wire flows horizontally toward the east.
A:force points toward south, 27 degrees below the horizontal
B:force points toward south, 27degrees above the horizontal
C:force points toward north, 63degrees above the horizontal
D:force points toward north, 27degrees above the horizontal

Part B:Find the magnitude of the magnetic force exerted on a 290m length of wire if the current in the wire flows horizontally toward the east.
F=_____N

Part C:Find the direction of the magnetic force exerted on a 290m length of wire if the current in the wire flows horizontally toward the south.

A:force points toward the north
B:force points toward the south
C:force points toward the west
D:force points toward the east

Part D:Find the magnitude of the magnetic force exerted on a 290m length of wire if the current in the wire flows horizontally toward the south.
F=______N
