Humans have been studying rocks for a long time. Each kind of rock is valued for different reasons including hardness, strength, color, scarcity, and more.

This article is about a very special kind of rock called lodestone.

Clearly lodestone isn't valued for its looks. What makes lodestone special is that it attracts iron shavings and steel! We call this property magnetism.
