Our planet is surrounded by an invisible force-field - its magnetic field. Generated deep within the Earth’s molten iron core, the field protects our planet from deadly radiation from space: without it life could never have evolved.

Our planet is surrounded by an invisible force-field - its magnetic field. Generated deep within the Earth’s molten iron core, the field protects our planet from deadly radiation from space: without it life could never have evolved. Yet scientists have recently discovered that something strange is now happening to the Earth’s magnetic field. It is growing rapidly weaker – at the present rate it will disappear altogether by the next millennium. Could our world lose its vital magnetic shield, and what will happen if we do?
