What is a permanent magnet? What types are there?
The size of the magnetic field is related to the size of the magnet and its strength. The easiest way to see a magnetic field generated by a permanent magnet is to disperse the iron filings around a bar magnet, which are quickly oriented along the field lines. Each permanent magnet has two poles, called north and south, although they could be
