EnglishThe strength of a permanent magnet depends on several factors, including:
1. Material composition: The type of material used to make the magnet affects its strength. Some of the most common materials used for permanent magnets include neodymium, samarium cobalt, and ferrite.
2. Shape and size: The shape and size of the magnet also affect its strength. The larger the magnet, the stronger it usually is. The shape of the magnet can also influence its strength, with some shapes (like discs and cylinders) being stronger than others.
3. Magnetic field orientation: The orientation of the magnetic field can also affect the strength of the magnet. A magnet with a field that is mainly oriented in one direction tends to be stronger than one with a more random field orientation.
4. Temperature: The strength of some permanent magnets may be affected by temperature. High temperatures can cause magnets to lose their magnetism or weaken over time.
5. External magnetic fields: The presence of external magnetic fields near a permanent magnet can also affect its strength. If a strong magnetic field is present nearby, it could cause the permanent magnet to align with it, potentially weakening the magnet's own field.
6. Manufacturing quality: The quality and precision of the manufacturing process used to make the magnet can also affect its strength. For example, a neodymium magnet with poor-quality manufacturing may not be as strong as one made with a higher level of quality control.
Understanding these and other factors that affect the strength of permanent magnets is important for choosing the right magnet for a specific application. Factors such as material, shape and size, and magnetic field orientation can be optimized to create a magnet with the desired strength and other performance for a particular use case.
Square magnet
The magnet is surrounded by six equal square faces, and the angle between any two adjacent faces of the magnet is a right angle.
This magnet is made of neodymium and is 21 times stronger than a ceramic magnet of the same size.
They are magnetized by thickness. They are composed of neodymium iron boron magnetic material, and are plated with nickel, copper and nickel, and have a shiny, corrosion-resistant surface.
