Countersunk pot magnet is a type of magnet that has a specially designed hole or depression on one face, which allows it to be easily attached or mounted onto surfaces using screws or bolts. Neodymium countersunk pot magnet is also called Neodymium countersunk cup magnet, Neodymium countersunk round base magnet, Neodymium countersunk mounting magnet.

Structure and Working Principle of Countersunk Pot Magnet:
Countersunk hole of the pot magnet is machined from the surface of the Neodymium disc magnet to the interior of the magnet. The purpose of the countersunk hole is to create a flush or recessed surface when the magnet is installed. By using screws or bolts that fit into the countersunk hole, the magnet can be securely fastened to a surface without protruding. This allows for a clean and flush appearance while maintaining a strong magnetic connection. Moreover, the steel pot protects the countersunk ring Neodymium magnet from damage in use.
Countersunk pot magnet has been one of the most popular structures of pot magnet types, Due to this simple structure, the countersunk pot magnet can be used to hold any ferromagnetic material onto a non-ferromagnetic surface, so it’s widely seen in industrial, warehouse, or even daily use like furniture assembly, signage, etc.
Typical Applications of Countersunk Pot Magnet:
1. Signage and displays: Countersunk round base magnet is commonly used in signage and display applications. They can be attached to the back of signs, banners, or display boards using screws or bolts. The countersunk hole ensures that the magnets sit flush with the surface, providing a clean and professional appearance.
2. Cabinetry and Woodworking: Countersunk Neodymium magnets are often used in cabinetry and woodworking projects to hold cabinet doors, drawers, or panels in place. The magnets can be embedded into the wood, and the countersunk holes allow for a flush installation without any visible protrusions.
3. Fixtures and fastenings: Cup magnets with a countersunk hole are utilized in various fixtures and fastening applications. They can be used to hold metal components, fixtures, or equipment securely in place. By using screws or bolts, the cup magnets can be easily attached to the desired surface, allowing for easy installation and removal.
4. Magnetic closures: Countersunk pot magnet can be employed in magnetic closures for doors, cabinets, or enclosures. The magnets can be recessed into the structure, and when paired with a corresponding metal plate or catch, they create a secure magnetic closure.
5. Industrial and engineering applications: Countersunk pot magnets can be used in jigs, fixtures, and machinery where magnetic holding or clamping is required. The countersunk holes allow for precise and secure mounting of the magnets onto various surfaces.

Magnets for PMSM (permanent magnet synchronous motors), particularly sintered Neodymium magnets (NdFeB), are integral components that determine the performance, efficiency, and reliability of PMSM motors. Neodymium magnets are essential components in modern electric motors, providing the necessary magnetic fields for efficient and powerful operation.
Samarium Cobalt ring magnet is the cylindrical shaped SmCo magnets with a center hole through the flat surfaces of magnets. The SmCo ring magnets are mainly used in sensors, magnetrons, high performance motors for example dental motors, microwave communication TWT (travelling wave tube), etc.
Neodymium block magnets are usually square and rectangular block shaped, which are the most common shape of Neodymium magnet. Usually we call them rare earth bar magnets, magnetic blocks, Neodymium bar magnets or rectangular Neodymium magnets. The strong block magnets are always used in industrial markets and small blocks may be used as craft magnets.
