A powerful magnet is an object that can attack a magnetic field. It is a magnetic dipole and can attract ferromagnetic substances such as iron, nickel, cobalt and other metals. The magnetic pole is determined by hanging a strong magnet with a thin wire, and the magnetic pole pointing to the north is called the north pole or the north pole, and the magnetic pole pointing to the south is the guide pole or the S pole. (If you think of the earth as a powerful magnet, today's geomagnetic north pole is the S pole, and the geomagnetic south pole is the N pole.) The strong magnets are attracted to each other and the same poles are crowded. The guide is extremely attracted to the North Pole, and the guide is extremely repulsive to the guide, referring to the repelling of the North Pole and the North Pole.
Classification of powerful magnets
Powerful magnets can be divided into "permanent strong magnets" and "non-permanent strong magnets". The permanent strong magnet can be a natural product, also known as a natural magnet, and can also be made by hand (the strongest strong magnet is a strong magnet). Rather than a permanent strong magnet, as long as it is magnetic under certain conditions, it is usually an electric strong magnet, or it is an electric current to strengthen its magnetic field.
Conversion of magnets and powerful magnets
The magnetic molecules inside the unmagnetized magnet (the molecular strong magnet theory) are randomly placed, and the magnetic molecules will be placed regularly after the magnetization process. At this time, the N pole and the S pole of the magnetic molecule will make the magnet magnetic in the same direction and become a strong magnet. Together, the same strong magnet has the opposite north and south poles and the magnetic quantity of the north and south poles is flat.
