
A paper clip stuck to a permanent magnet was
able to pick up a small washer. The nail could
pick up the washer because…


A magnet attracted a nail even when a pack of
post-its was placed in between it. Then, when
someone tried to put a small sponge between
the magnet and nail, the nail fell. Why?
 A: Magnetism can travel through paper and
not sponges.
 B: The sponge soaked up the magnetism.
