WebMagnetic fields Magnetic fields arise from permanent magnets and electric charges in motion. Magnets can occur naturally (such as the Earth’s magnetic field), or they can be made by magnetizing ferromagnetic materials. Magnetic fields ultimately are the result of the motion of charges. WebThe magnetic field is represented by field lines that start at a magnet’s north pole and end at the south pole. bbc.co.uk . When most people think of magnetism, they think about the magnetic force experienced between two magnets. The magnetic force is caused by the magnet’s magnetic field and points in the direction of the field lines.
