How to mount a disc magnet?

Nov 26, 2025|

Hey there! As a disc magnet supplier, I often get asked about how to mount disc magnets. It's a pretty common question, and I'm here to share some tips and tricks with you.

First off, let's talk about what disc magnets are. Disc magnets, also known as Disc Magnets, are flat, circular magnets with a thickness that's usually less than their diameter. They come in various sizes and strengths, and are made from different materials like neodymium, ferrite, and samarium cobalt. These magnets are super versatile and are used in a wide range of applications, from electronics and motors to crafts and DIY projects.

Preparation Before Mounting

Before you start mounting a disc magnet, there are a few things you need to do.

Safety First

Disc magnets, especially the neodymium ones, can be extremely powerful. They can snap together with a lot of force, which can cause injuries like pinched fingers or even broken bones. So, always wear safety gloves and goggles when handling these magnets. Also, keep them away from electronic devices, pacemakers, and credit cards as the magnetic field can damage them.

Choose the Right Magnet

The first step in mounting a disc magnet is to choose the right one for your project. Consider the size, strength, and material of the magnet. For example, if you're working on a small DIY project, a 6x2mm Disc Magnet might be sufficient. But if you need a stronger magnet for an industrial application, you might want to go for a larger and more powerful one.

Select the Mounting Surface

The surface where you'll be mounting the magnet is crucial. It should be clean, dry, and flat. Any dirt, grease, or unevenness can affect the magnet's performance. If the surface is dirty, clean it with a mild detergent and water, and then dry it thoroughly.

Mounting Methods

There are several ways to mount a disc magnet, and the method you choose depends on your specific needs and the materials you're working with.

Adhesive Mounting

One of the most common ways to mount a disc magnet is by using adhesive. This method is great for non-metallic surfaces or when you don't want to drill holes.

  • Choose the Right Adhesive: There are many types of adhesives available, such as epoxy, cyanoacrylate (super glue), and double-sided tape. Epoxy is a strong and durable adhesive that can withstand high temperatures and heavy loads. Cyanoacrylate is quick-drying and works well for small magnets. Double-sided tape is easy to use and can be removed without leaving much residue.
  • Apply the Adhesive: Follow the instructions on the adhesive package. For epoxy, you'll usually need to mix two components together. Apply a thin layer of adhesive to the back of the magnet or the mounting surface. Make sure to cover the entire area evenly.
  • Attach the Magnet: Carefully place the magnet on the mounting surface and press it firmly for a few seconds to ensure good contact. Hold it in place until the adhesive sets.

Mechanical Mounting

Mechanical mounting involves using screws, bolts, or clips to attach the magnet. This method is more secure and is suitable for heavy-duty applications.

  • Drill Holes: If you're using screws or bolts, you'll need to drill holes in the magnet and the mounting surface. Make sure the holes are the right size and alignment. Use a drill bit that's slightly smaller than the diameter of the screw or bolt.
  • Insert the Fasteners: Insert the screws or bolts through the holes in the magnet and the mounting surface. Tighten them using a screwdriver or wrench. Be careful not to overtighten, as this can crack the magnet.
  • Use Clips: Clips are another option for mechanical mounting. They can be easily attached and removed, making them a good choice for temporary installations.

Magnetic Attraction

In some cases, you can simply rely on the magnet's own magnetic force to hold it in place. This method is suitable for lightweight magnets and when the mounting surface is made of a ferromagnetic material like iron or steel.

  • Position the Magnet: Place the magnet on the mounting surface and let the magnetic force hold it in place. Make sure the magnet is centered and aligned properly.

Testing the Mounted Magnet

Once you've mounted the magnet, it's important to test it to make sure it's secure and working properly.

  • Check the Strength: Try to pull the magnet gently to see if it's firmly attached. If it moves or comes loose, you may need to reapply the adhesive or tighten the fasteners.
  • Test the Functionality: If the magnet is part of a larger system, test the system to make sure the magnet is performing as expected.

Troubleshooting

If you encounter any problems during the mounting process, here are some common issues and solutions.

  • Weak Adhesion: If the magnet isn't sticking well, the adhesive may not be strong enough or the surface may not be clean. Clean the surface again and try using a different adhesive.
  • Cracked Magnet: If the magnet cracks during drilling or tightening, it's likely due to excessive force. Use a drill bit that's the right size and be careful when tightening the fasteners.
  • Magnet Not Aligned: If the magnet isn't centered or aligned properly, remove it and reposition it. Make sure to measure and mark the correct position before attaching the magnet.

Conclusion

Mounting a disc magnet isn't as difficult as it may seem. By following these tips and choosing the right method for your project, you can ensure a secure and successful installation. Whether you're a DIY enthusiast or an industrial professional, disc magnets can add a lot of functionality to your projects.
