Paper clips are typically made from steel with a fine coating of zinc to prevent rust and corrosion. Can a magnet pick up a paper clip from the bottom of an aquarium?

• Yes, but only if the aquarium is empty (not in water)

• Yes, even in water

• No, the metals in a paper clip are nonmagnetic

Answer explanation

Steel is an alloy of IRON and other metals.

Iron is a magnetic metal and will be attracted to a magnet.

The magnet will work in water just fine and have no trouble picking up the paper clip.
