Write a brief history of magnets.

(N/A) The property of attraction exhibited by certain materials is called magnetism,and an object possessing such properties is called a magnet.
Magnetic phenomena are universal in nature.
The Earth's magnetism predates human evolution.
Magnetism is spread across the entire universe,including our Earth.
The word 'magnet' is derived from the name of an island in Greece called Magnesia,where magnetic ore deposits were found as early as $600 \ BC$.
Legend has it that shepherds on this island complained that their wooden shoes,which had iron nails,would stick to the ground. Their iron-tipped rods were similarly affected. This attractive property of magnets made it difficult for them to move around.
From the name of the island 'Magnesia',the phenomenon and the object became known as 'magnet' in English.
