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 ...

Earth’s magnetic field sustains life on our planet, protecting us from solar winds, radiation and extreme changes in temperature. But around 591 million years ago, it almost collapsed.

While shifting is not a rare occurrence, the pole is moving both faster and differently than it was before, raising questions about the planet's magnetic field. If the Earth's field is disrupted ...

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 ...
