A magnet is placed near a pile of steel paper clips. Which will most likely occur?

• The magnet will provide a balanced force, causing the paper clips to spin in

• The magnet will provide an unbalanced force, keeping the paper clips stationary.

• The magnet will provide a balanced force, pushing the paper clips away from it.

• The magnet will provide an unbalanced force, pulling the paper clips toward it.
