Other proposals

A magnetic holder (magnet in a steel cup) is much stronger on one side than a bare magnet of the same dimensions. The metal cover secures the magnet against mechanical damage, which is common in workshop conditions. The threaded hole allows creating a functional mounting point in seconds.
Too long a screw can pass through the bushing and push out or damage the magnet glued into the bottom of the cup. Neodymium magnets are brittle, and direct pressure from a screw can cause them to crack or detach. You can use a spacer washer or lock nut to limit screwing depth.
They are indispensable when building exhibition stands and shop displays (POS systems). They allow mounting without drilling in steel substrate, which is crucial in rented spaces. In the workshop, they can serve as mounting points for tools or measuring instruments.
This value applies to perfect adherence with the entire magnet surface. On a thin surface or painted cabinet, the magnet will hold much weaker (even by 50-70%). We always recommend choosing a magnet with power reserve, especially if the surface is not ideal.
Standard coating effectively protects against moisture in indoor conditions. For outdoor applications, we recommend additional protection with varnish or choosing a rubberized (hermetic) version. The neodymium magnet itself inside is also nickel-plated.

Pros and cons of Nd2Fe14B magnets.

Strengths

Apart from their superior power, neodymium magnets have these key benefits:
  • They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
  • They feature excellent resistance to magnetic field loss when exposed to external magnetic sources,
  • Thanks to the reflective finish, the layer of nickel, gold-plated, or silver gives an professional appearance,
  • The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
  • Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
  • Possibility of detailed modeling as well as optimizing to defined applications,
  • Key role in innovative solutions – they are utilized in hard drives, motor assemblies, medical devices, as well as other advanced devices.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Limitations

Problematic aspects of neodymium magnets: weaknesses and usage proposals
  • At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
  • They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Limited possibility of making nuts in the magnet and complex shapes - preferred is a housing - magnet mounting.
  • Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, small elements of these magnets can disrupt the diagnostic process medical in case of swallowing.
  • With budget limitations the cost of neodymium magnets is a challenge,

Holding force characteristics

Best holding force of the magnet in ideal parameterswhat it depends on?

Magnet power was defined for ideal contact conditions, including:
  • on a plate made of structural steel, perfectly concentrating the magnetic field
  • with a thickness of at least 10 mm
  • with a surface cleaned and smooth
  • under conditions of no distance (surface-to-surface)
  • under perpendicular application of breakaway force (90-degree angle)
  • in stable room temperature

Magnet lifting force in use – key factors

During everyday use, the actual holding force is determined by many variables, ranked from most significant:
  • Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
  • Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
  • Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
  • Material composition – different alloys attracts identically. Alloy additives weaken the attraction effect.
  • Surface condition – smooth surfaces ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
  • Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, however under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet and the plate lowers the lifting capacity.

H&S for magnets
Immense force

Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.

Magnetic media

Avoid bringing magnets near a wallet, laptop, or screen. The magnetic field can permanently damage these devices and erase data from cards.

Permanent damage

Avoid heat. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, look for HT versions (H, SH, UH).

Skin irritation risks

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If redness happens, immediately stop working with magnets and use protective gear.

GPS Danger

Remember: rare earth magnets produce a field that confuses sensitive sensors. Keep a safe distance from your phone, device, and GPS.

Choking Hazard

Adult use only. Small elements can be swallowed, leading to severe trauma. Keep away from children and animals.

Finger safety

Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!

Material brittleness

Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Dust is flammable

Fire hazard: Neodymium dust is explosive. Avoid machining magnets in home conditions as this may cause fire.

Medical interference

Warning for patients: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or request help to work with the magnets.

Caution! Learn more about hazards in the article: Magnet Safety Guide.
