This video introduces permanent magnets and their fields. Around a permanent magnet, like the traditional bar magnet, is a region where other magnets and magnetic materials experience a force. This region is called a magnetic field. The Earth has its own magnetic field, which is why compasses all point in the same direction, towards the North Pole.

The magnetic field of a magnet goes from the north end to the south end. The strength of the magnetic field is represented by how close the field lines are. The closer the field lines are together, the stronger the magnetic field is. The magnetic field between the opposite ends of two magnets is uniform so is represented by parallel lines going from north to south.

Thanks for watching,
