Write a brief history of magnet.

The properties of attraction by a iron is called magnetism and the object with such properties posses is called a magnet.

Magnetic phenomena are universal in nature.

The Earth's magnetism predates human evolution.

Magnetism are spread across the entire universe including in 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 $600 \mathrm{BC}$. Shepherds on this island complained that their wooden shoes which had nails at time stayed struck 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 island magnesia, phenomena of the wooden shoes which had nails struck to the ground is 'magnet' in English.
