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).

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.

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.

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.

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.

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.
