Various shapes of magnets
1. Bar magnet
The power of the magnet is concentrated on the two poles, and weaker on the sides. They are the most commonly used shapes in daily life, such as refrigerator magnets and compasses. Bar magnets are also often used for demonstrations in classrooms. For example, you can use a bar magnet to display the magnetic field by spreading metal shavings on paper that hides the magnet.
2. Horseshoe magnet
A horseshoe magnet is a U-shaped bar magnet. The U shape makes the magnetic poles point in the same direction, which makes the magnet stronger. Initially as a substitute for bar magnets, this shape has become a universal symbol for magnets. Depending on the strength of the horseshoe magnet, it can be used to pick up metal objects of any size. For example, small horseshoes can collect paper clips, while industrial-sized horseshoe magnets are used in construction and engineering to collect large chunks of heavy metals, and horseshoe magnets are also used on the bottom of a pendulum.
3. Round magnet
A circular magnet can increase its attractive force by increasing its thickness. Because the surface of the circular magnet is wide and flat, and the magnetic pole area is large, it becomes a strong and effective magnet. According to the size of the circle, this shape has many uses, such as packaging handbags, personal experiments, electronic products, smart homes, etc.
4. Spherical magnet
Spherical magnets are often sold as toys and novel items. Spherical magnets can be used to make popular tabletop toys, such as rattlesnake eggs. The shape can also be used to make bracelets and necklaces.
5. Cylindrical magnet
A magnet with a height greater than its diameter is usually magnetized in a radial direction. Of course, it can also be magnetized in an axial direction. It mainly depends on the actual needs of customers. It is suitable for magnetic toys, Hall sensors, galvanometers, and medical equipment.
6. Ring magnet
Ring magnets are very versatile and are usually used in scientific experiments. For example, when demonstrating magnetic repulsion, the magnetic ring is passed through a wooden pole. When the same magnetic poles are in contact with each other, they will not touch each other, as well as magnetic levitation, electric motors, electroacoustics, Salvage, medicine, etc., a lot.
7. Tile-shaped/arc-shaped magnet
Tile magnets, also called arc magnets, curved magnets, are often used in various permanent magnet DC motors.
8. Counterbore magnet
That is to make a counterbore on the basis of round, square, cylindrical, ring, tile-shaped magnets, and use them with screws.
9. Special-shaped magnets
The above magnets are relatively common magnets, and special-shaped magnets are mainly used in special occasions, such as magnetic connectors and some non-standard parts. Common special-shaped magnets include large and small magnets, T-shaped magnets, bevel magnets, and semicircular magnets. , Concave and convex magnets, slotted magnets, etc.
