A power cord for an appliance contains two parallel wires (separated by an insulator) that carry equal currents inopposite directions. Consider the force exerted on the cord by Earth's magnetic field. Suppose the cord is horizontaland oriented in an East-West direction, and Earth's magnetic field points toward the north at an angle of 30 degreesbelow horizontal. The net magnetic force on the cord would be...Select one:a. ... directed horizontally toward the northcross outb. .. directed vertically downward (toward the ground)cross outc. ... directed vertically upward (away from the ground)cross outd. ... directed toward the south, at an angle 60 degrees below horizontalcross outcross oute.
