Permanent Magnets: A Study in Sticktoitiveness

Permanent Magnets: A Study in Sticktoitiveness There are two basic kinds of magnets  permanent and temporary. We'll take on permanent first  which is appropriate, because before humans could invent and exploit temporary magnets, they had to discover the permanent kind first. People first happened upon magnets sometime before 600 BC with the discovery of the [...]
