Which statement is true about magnets?

• Magnets will attract other magnets if like poles are brought together.

  Example : North pole and North Pole

• Magnets will repel other magnets if unlike poles are brought together.

  Example: North Pole and South Pole

• The strength of a magnet is weakest at its poles.

• The strength of a magnet is greatest at its poles.

A student arranges two magnets so that the north poles of the magnets are close to each other. How will the magnetic force act in this arrangement?

• The magnetic force will cause the magnets to attract one another.

• The magnetic force will cause the magnets to repel one another.

• The magnetic force will cause the magnets to move parallel to one another.

• The magnetic force will cause the magnets to remain in the same position.

• small

  closer to

• small,

  farther from

• heavy,

  closer to

• heavy,

  farther from
