Thales of Miletos (624 BC -546 BC)
Thales of Miletos was greek philosopher, mathematician and natural scientist in the 6th century BC. He observed that loadstones attracted iron.
A loadstone is a naturally occurring magnet. It is a form of iron ore that keeps it’s magnetic properties, perhaps after being struck by lighting. If iron is struck by lighting it will become magnetic for a short time. We can simulate Thales observations.
