Different Shapes of Magnets and Their Uses

Different shapes of magnets have different uses. Learn about Alnico, Ceramic, and Neodymium countersunk ring magnets. You’ll also find information on NdFeB countersunk ring magnets. These materials are commonly used in electronic components. In addition to being functional, these magnets can also be used as street art.
Neodymium ring magnets

Neodymium ring magnets are made from neodymium metal. The material is highly magnetic and can be used to create sculptures and objects. However, the magnets can also be easily corroded in moist environments. To avoid this, it is important to protect these magnets from corrosion.

Neodymium ring magnets are made of strong material and come in many different shapes. They are available in a range of diameters, and have countersunk or drilled holes in the center for easy mounting. This allows them to fit flush with other objects.
Alnico ring magnets

Alnico ring magnets are made from aluminum, nickel, cobalt, iron, and other elements. They are made in two different methods, casting and sintering. The former method has slightly lower magnetic properties, but allows for tighter dimensional tolerances. The latter method, however, yields a higher mechanical strength.

The process of casting involves pouring the molten mixture into green sand molds. The molds should be large enough to account for shrinkage during cooling. In some cases, several molds are required to produce a certain size of alnico magnet. These molds are connected by gates. The molten material is then transferred from one mold to the other through the gates.
Ceramic ring magnets

Ceramic ring magnets are a popular type of magnet and are used in many applications. The strength of the magnetic field is very strong and they are durable. Ceramic ring magnets are generally available in packs of 100 or 1000. Children may use ceramic ring magnets in science projects or experiments. They can be used to map magnetic fields.

Ceramic magnets are commonly used in many products, from large communication systems to large speakers. They are also widely used in electronic devices, such as recorders and speakers.
NdFeB countersunk rings

Countersunk magnets, also known as neodymium magnets, are rings that have a hole in the middle. This allows them to have very high magnetic pressure. They can hold five to seven times as much force as ceramic magnets, making them ideal for a variety of applications. These magnets are widely used for fixing and closure applications, and they are available in a variety of sizes.

They are sold in pairs, each with a countersunk hole in one side. When assembled, countersunk ring magnets can be used to build magnetic latches, fasteners, and closure mechanisms. This is because both poles are magnetic, and therefore can be used to lock or unlock items.
Neodymium counterbore rings

Neodymium counterbore rings have a 90-degree countersunk hole. They are designed to fit screws with 6.4-mm diameters. These rings are available in different shapes, including cylindrical and square. They are packaged with separators based on their type. Neodymium counterbore rings are magnetically attractive and can stick to metal surfaces. However, they can break if they are subjected to too much force or torque.

Neodymium counterbore rings are composed of two components: a magnetic steel body and a neodymium counterbore. The ring body is axially magnetised, and the lower portion is bounded by a ring-shaped counterbore. The cross-section of the ring is based on an isosceles trapezoid. The ring body is covered with a nickel-plated layer.
