A compass needle normally points toward Earth’s 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.

If the particles in a sample of matter have an orderly arrangement and move only in place, the sample is a
