Why do compass needles point north-but not quite north? What guides the migration of birds, whales, and fish across the world's oceans? How is Earth able to sustain life under an onslaught of solar wind and cosmic radiation? For centuries, the world's great scientists have grappled with these questions, all rooted in the same phenomenon: Earth's magnetism. Over two thousand years after the invention of the compass, Einstein called the source of...

Le magnétisme est l'un des phénomènes qui a le plus frappé l'imagination de l'homme, au point que ce mot désigne aujourd'hui des réalités très diverses : il s'agit d'abord d'une science fort ancienne et néanmoins toujours d'actualité dont le champ d'application ne cesse de s'étendre ; ensuite, ...
