or for the coil to be rotated round the magnet. This method of generating electricity, called induction, was discovered by Michael Faraday in 1831. He found that the stronger the magnets were ...

As with all currents, the induced current creates a magnetic field around itself. Note that this magnetic field opposes the original change. For example, if a magnet is moved into a coil of wire ...

The magnetic north pole is once again on the move—this time inching ever closer to Siberia. Scientists have updated the World Magnetic Model as the magnetic north pole shifts closer to Siberia ...
