Disc Magnets FAQ


What are disc magnets used for?

Disc magnets are integral components in various applications due to their versatile shape and powerful magnetic properties. In manufacturing, they are used to hold and secure components during assembly and fabrication processes. The electronics industry relies on disc magnets for the operation of sensors and switches, providing precise and reliable magnetic fields for detecting and activating devices. They are also essential in magnetic separation equipment, helping to remove ferrous contaminants from product streams and ensuring product purity. In the production of electric motors and generators, disc magnets enhance efficiency and performance with their strong magnetic fields. Automation and robotics benefit from disc magnets as they create magnetic couplings and mounts, enhancing the flexibility and functionality of robotic systems. Packaging machinery utilises disc magnets to control and stabilise moving parts, ensuring precision in labelling and sealing processes. By leveraging the strength and reliability of disc magnets, businesses can improve efficiency, precision, and product quality in their operations.

How strong are disc magnets?

The strength of a disc magnet depends on its size and the material it is made from. Neodymium disc magnets, for instance, are among the strongest available, with some small discs being able to hold up to several kilograms of weight. Whereas ferrite magnets are lower in strength. Each Strength is usually measured in terms of pull force or magnetic flux density (measured in Gauss or Tesla).

Are disc magnets safe to use?

Disc magnets are generally safe to use, but they can be hazardous if not handled properly. They can snap together with great force, potentially causing injury. Small magnets can be a choking hazard and are extremely dangerous if swallowed, as they can cause serious internal damage. It’s important to keep them away from children and electronics, as their strong magnetic fields can damage devices like pacemakers and credit cards so please use them appropriately.

Can disc magnets lose their magnetism?

Yes, disc standard magnets can lose their magnetism over time or if they are exposed to certain conditions. Factors that can cause a loss of magnetism include high temperatures, strong opposing magnetic fields, physical damage, and corrosion. However, high-quality disc magnets, especially those made from neodymium, typically retain their magnetism for many years under normal conditions. If you require magnets that can withstand higher temperatures of corrosive environments please get in touch we can manufacture custom disc magnets to meet your needs.

What are the differences between neodymium and ferrite disc magnets?

Neodymium disc magnets are much stronger than ferrite (ceramic) disc magnets and are usually smaller for the same amount of strength. Neodymium magnets are more expensive and can corrode easily without a protective coating, whereas ferrite magnets are cheaper, more resistant to corrosion, but much weaker. Neodymium magnets are typically used in high-performance applications, while ferrite magnets are suitable for general use where high strength is not critical.

How can disc magnets be used in DIY projects?

Disc magnets are popular in DIY projects due to their strength and ease of use. They can be used for creating magnetic closures for boxes and cabinets, in homemade tools, for securing items in workshops, in educational models to demonstrate magnetic principles, and even in creative art and craft projects.

Can you drill disc magnets?

Drilling disc magnets is generally not recommended. The material they are made from, especially neodymium, is very brittle and can easily crack or shatter under the stress of drilling. Additionally, drilling generates heat, which can demagnetise the magnet. If a hole is needed in a disc magnet, it is best to purchase magnets that are pre-drilled. If drilling is unavoidable, it should be done very slowly and with cooling to minimise heat build-up, but this still carries a high risk of damaging the magnet. If you are unable to find a countersunk or counterbore disc magnets that meets your need please get in touch and we can manufacture them for you.
