Uses of Magnets of Different Shapes

Jan. 14, 2021

Sintered NdFeB magnets, as a new generation of magnets with higher performance and stronger magnetic force, must be very familiar to everyone. So, in neodymium magnets, what are the differences between magnets of various shapes? Today, Neodymium Magnet Suppliers will introduce the differences and uses of magnets of different shapes.

1. Bar magnet

The magnetic force of the Bar Neodymium Magnet is mainly at the two ends of the magnet, and the two sides of the magnet are weak. This type of magnet is the most common shape in our daily life and the most used shape in industrial production, such as the magnetic stickers of refrigerator doors, and linear motors . Normally, according to the design, the square bar magnet can be inserted into the motor to be fixed around the stator to provide a magnetic field.

2. Horseshoe magnet

The horseshoe magnet is a representative U-shaped magnet. The U shape makes the magnetic poles point in the same direction, making the magnet stronger. Originally as a substitute for bar magnets, this shape has become a universal symbol for magnets. Magnets of this shape are mostly used in point magnets. A conductive winding that matches its power is wound on the outside of the iron core. This current-carrying coil has magnetism like a magnet, and it is also called an electromagnet. We usually make it into a strip or hoof shape to make the iron core easier to magnetize. In addition, in order to demagnetize the electromagnet immediately after power failure, we often use soft iron or silicon steel materials that demagnetize faster. Such an electromagnet has magnetism when it is energized, and the magnetism disappears after the power is off. Electromagnets are extremely widely used in our daily lives. Because of its invention, the power of generators has been greatly improved.

3. Round magnet

Circular magnets are the earliest magnet shapes used by humans. With the deepening of human understanding based on neodymium magnets, circular neodymium iron boron magnets have gradually come into everyone’s eyes and are gradually being used by people. They are currently widely used in various household appliances. Among them, the most common one at present is the horn, which is also the product closest to everyone’s life. It is mainly composed of a circular neodymium iron boron magnet and a copper coil. The coil generates a current, and the current generates a magnetic field and a circular neodymium iron boron magnet magnetic field. Interference to produce a variety of beautiful sounds, as well as transformers that are widely used today. In addition, the application of circular magnets in mobile phones or computers is necessary.

4. Cylindrical magnet

This type of magnet is similar to a round magnet, except that the thickness is greater than the length of the diameter. It is usually radial magnetization. Of course, according to different designs and requirements, it can also be axial. It is suitable for magnetic toys, some sensors and medical detection equipment.

5. Ring magnet

Ring magnets have a wide range of uses. They are not only used in conventional electronic and electroacoustic products and motor products. At the same time, the designer will also design the pole direction of the magnet as a radial magnetic ring to replace the motor magnetic field composed of multiple sets of tiles. . Compared with a motor composed of multiple sets of tiles, a motor composed of a single radiating magnetic ring has lower cost and better performance.
