China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Tiny round (circle) magnets are magnets with a very small diameter size (usually in the range of a few millimeters or less) and a round shape, they are usually made of neodymium-iron-boron, ferrite, samarium cobalt, or other magnetic materials, and they are commonly used in precision devices, sensors, meters, electronic products, handicrafts, personal DIY, etc.

When using tiny circle magnets, users may encounter some problems, the following are some common problems and solutions
1. How much weight or tension can a tiny circular magnet withstand?
The pulling force of a tiny round magnet depends on the size, material and performance level of the magnet. For example, NdFeB magnets usually have stronger magnetic force, but the smaller the size, the less weight or pull force it can carry.
2. Do tiny round magnets corrode? How can I prevent it?
Tiny round magnets, especially NdFeB magnets, are susceptible to moisture and corrosive environments. To prevent corrosion, the surface of the magnet is often plated, such as nickel-plated, zinc-plated, or epoxy-coated. If the magnet is used in a humid environment or exposed to chemicals, it is recommended to use an anti-corrosion coating, or choose a material with better corrosion resistance, such as ferrite, samarium cobalt material.
3. Can tiny circle magnets withstand high temperatures?
Different types of magnets have different temperature resistance properties. NdFeB magnets are less stable at high temperatures and usually lose some of their magnetic properties between 80°C and 220°C. If you need to use them in a high temperature environment, it is recommended to choose high temperature resistant magnets such as AlNiCo or SmCo magnets, which have higher temperature resistance and can withstand higher temperatures.
4. How to choose the right material for tiny round magnets?
Choosing the right magnet material needs to be weighed against the needs of the specific application. NdFeB magnets have a strong magnetic force, but are less resistant to temperature and corrosion, and are suitable for high-precision, small-size devices. Ferrite magnets, on the other hand, are more suitable for low-cost, high-volume applications, although the magnetic force is weaker, but better corrosion resistance and high temperature resistance. If the application environment is more severe, you can choose samarium cobalt or alnico magnets with stronger temperature resistance and corrosion resistance.
5. Can Tiny circle Magnets be machined or customized?
Tiny round magnets can be machined, and common machining methods include cutting, drilling, and coating treatments. Customized magnets are especially important in specific applications. For example, a customer may require a magnet of a particular size and tight tolerance, shape, or finish. Manufacturers often offer customization services to produce tiny round magnets that meet the specifications of the customer's needs.
