How to mount a magnet?

Magnets are used in thousands of applications, from displays and machine construction to interior design and industrial constructions. However, the influence of mounting on the ultimate performance of a magnet is often underestimated.

Even the strongest neodymium magnet delivers less holding force when incorrectly attached. The choice of the right mounting method is therefore at least as important as the choice of the magnet itself.

In this article, we discuss the most common ways to mount magnets and when each solution is most suitable.

Why is mounting important?

A magnet performs best when it makes full contact with a flat steel surface.

When a magnet is mounted crookedly, receives insufficient support, or is placed on an unsuitable surface, the actual holding force can be significantly lower than the theoretical value.

Therefore, in professional applications, both the magnet and the mounting structure are always considered.

Self-adhesive magnets

One of the simplest ways to attach a magnet is with a self-adhesive version.

On the back, there is a strong adhesive layer with which the magnet can be attached to various surfaces.

Self-adhesive magnets are often used for:

• displays
• POS material
• packaging
• signage
• light covers

For optimal adhesion, the surface must be clean, dry, and free of grease.

Magnets with screw hole

When a permanent and sturdy attachment is required, magnets with a screw hole are often chosen.

The magnet can be directly secured with a screw or bolt, making shifting almost impossible.

This solution is widely used in:

• machine building
• furniture making
• interior design
• technical installations

The mechanical attachment ensures reliable mounting, even with vibrations or intensive use.

Magnets with countersunk hole

With a countersunk hole, the screw head completely recesses into the magnet.

This creates a flat finish without protruding parts.

Magnets with a countersunk hole are often used when a neat finish is desired, for example, for:

• doors
• hatches
• displays
• advertising panels
• furniture

In addition, the magnet is evenly loaded, which benefits durability.

Pot magnets

A pot magnet consists of a neodymium magnet housed in a steel casing.

This construction offers several advantages.

The steel pot:

• protects the magnet
• concentrates the magnetic field
• increases holding force
• simplifies mounting

Pot magnets are available with thread, threaded bush, hook, eye, or countersunk mounting.

Rubber coated magnets

On sensitive surfaces, a standard magnet can cause scratches.

Rubber coated magnets offer a solution for this.

The rubber layer:

• protects the surface
• increases friction
• reduces shifting
• offers extra protection against moisture

This makes them popular in vehicles, display systems, and outdoor installations.

Gluing magnets

In some applications, magnets are directly glued.

Strong construction adhesives or industrial adhesive systems are usually used for this.

It is important that the adhesive is suitable for both the surface and the load of the application.

For high tensile forces, mechanical fastening is often preferred.

Which mounting method do you choose?

The right choice depends on various factors:

• load
• environment
• surface
• desired lifespan
• aesthetic requirements
• maintenance

A self-adhesive magnet may be ideal for a display, while a pot magnet with a countersunk hole is better suited for an industrial application.

Therefore, it is wise not only to look at the holding force of the magnet but also at how it is attached.

Conclusion

The performance of a magnet is determined not only by the magnet itself but also by the way it is mounted. Depending on the application, one can choose self-adhesive magnets, screw mounting, countersunk fastening, pot magnets, rubber-coated versions, or gluing. The correct mounting method ensures safe, durable, and reliable operation.
