Question

what is a magnet and who found it and how it works​

Answer 1

Answer:

a piece of iron, steel, etc. that can attract and pick up other metal objects

It was found from a naturally occurring mineral called magnetite. Traditionally, the ancient Greeks were the discoverers of magnetite. There is a story about a shepherd named Magnes whose shoe nails stuck to a rock containing magnetite

All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.
