a compass needle normally points toward earths magnetic pole, which is near the north pole. which best explains why the needle 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 pole. current within the wire draws the needle toward the wire. magnetism surrounding the wire draws the needle toward the wire.
Answer
# Brief Explanations:
A current - carrying wire produces a magnetic field around it according to Ampere's law. This magnetic field interacts with the magnetic field of the compass needle. The compass needle moves because the magnetism surrounding the wire exerts a force on it, drawing it towards the wire. The wire's magnetic field is not weakening the Earth's magnetic pole's force but rather creating a competing magnetic influence.
# Answer:
D. Magnetism surrounding the wire draws the needle toward the wire.
