Likewise, a wire passing through a magnetic field creates an electric current within the wire. This is the basic principle that allows electric motors and generators to operate. In the Earth (see ...

Geophysicist Daniel Lathrop wants, among other things, to use it to predict when the Earth’s magnetic field will next reverse. Over the course of our planet’s history, the field has flipped ...

When the Earth’s magnetic field is strong, as it is today, the amount of carbon generated by this interaction is relatively low, but it spikes when the magnetic field weakens and allows more ...

But not everyone is convinced. Electricity can be generated from the energy of Earth rotating through its own magnetic field — according to a provocative claim put forward by physicists today.
