The magnetite is made of iron oxide powder with a filler and a binder. The scientific name is a magnet. A magnet is an object that can attract iron and generate a magnetic field outside it. Strong magnetite refers to a magnet with very strong magnetic force. The following is a brief introduction for you, hoping to bring you some help. Magnets can attract metals such as iron, nickel, and cobalt. Can be divided into common permanent magnets, and electromagnets that have magnetism only when energized. If magnets are made into rods or needles and hung, they will naturally point to the north and south poles of the earth. Magnets are divided into large magnets and small magnets. 1. Large magnets Magnets have a wide range of uses. Electromagnets are used to make cranes that transport steel. When electrified, it becomes a strong magnet, so it can attract heavy steel. Just turn off the power when putting down the steel. 2. Small magnets Compared with large magnets, the compass appears to be smaller and lighter, and its magnetism is much weaker. The purpose of the compass is not to attract iron, but to reflect the magnetic force of the earth.
The property that magnets attract iron, cobalt, nickel and other substances is called magnetism. The magnetically strong area at both ends of the magnet is called the magnetic pole, with one pole at the north pole (N pole) and one pole at the south pole (S pole). Experiments have shown that homopolar magnetic poles repel each other, and opposite magnetic poles attract each other. There are many protomagnets with two opposite magnetic poles in iron. When there is no external magnetic field, these protomagnets are disorderly arranged. Their magnetic properties cancel each other out and do not show magnetic properties to the outside. When iron is brought close to the magnet, these original magnets are neatly arranged under the action of the magnet, so that the end near the magnet has a polarity opposite to that of the magnet and attracts each other. This shows that iron can be magnetized due to the existence of the original magnet. Metals such as copper and aluminum have no original magnet structure, so they cannot be attracted by magnets.
