This means that the magnetic field lines surrounding a magnet always form closed loops. We measure magnetic fields using a unit called the tesla, which is one Newton per Ampere-meter.

Earth’s magnetic field behaves like a giant bar magnet. The movement of molten iron in the core generates the field, and field lines loop between the two magnetic poles.

Every magnet that we have ever observed is a dipole — it has both a north and south pole. If we draw magnetic field lines around a magnet, we always see the lines curve around, joining the two ...
