Compass needle normally points toward Earth's magnetic pole, which is near the North Pole. Which best explains why the
eedle moves away from the pole when it comes close to a current-carrying wire?
Current within the wire weakens the magnetic force of the pole.
Magnetism surrounding the wire weakens the magnetic force of the nole
