Other deals

A magnet with a built-in screw is great for screwing with a nut to housings, profiles, and flat bars. Just pass the thread through the hole in the element and tighten the nut on the other side. Used for mounting sensors, panels, plates, and exhibition elements.
The threaded stud is an integral part of the steel housing, but avoid overtightening the thread. Do not use the magnet as a structural bolt transferring huge mechanical loads in shear. The magnet itself is protected by a steel cup and is very resistant to impact.
Standard neodymium holders are adapted to work in temperatures up to 80°C. If you need resistance to higher temperatures, ask about special versions (H, SH). Remember that even momentary overheating can weaken the holder.
Thread size (e.g., M6) is always given in the product name and technical specification. Stud length varies depending on the model (usually from 8 to 15 mm). It is a solid threaded connection, ready for use.
Thanks to shielding the sides and top, all magnet power is directed downwards, giving higher capacity than a bare magnet. This force drops very quickly with increasing distance (air gap).

Advantages as well as disadvantages of neodymium magnets.

Strengths

Besides their stability, neodymium magnets are valued for these benefits:
  • They retain attractive force for around 10 years – the drop is just ~1% (based on simulations),
  • They are resistant to demagnetization induced by external disturbances,
  • By covering with a smooth layer of nickel, the element acquires an proper look,
  • Neodymium magnets ensure maximum magnetic induction on a small area, which increases force concentration,
  • Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
  • Thanks to freedom in designing and the ability to modify to individual projects,
  • Significant place in electronics industry – they are commonly used in mass storage devices, electromotive mechanisms, medical equipment, and other advanced devices.
  • Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Cons

Disadvantages of NdFeB magnets:
  • To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
  • Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
  • Limited possibility of producing threads in the magnet and complicated forms - recommended is a housing - magnetic holder.
  • Health risk resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these products can complicate diagnosis medical after entering the body.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Maximum magnetic pulling forcewhat contributes to it?

Information about lifting capacity is the result of a measurement for ideal contact conditions, taking into account:
  • on a base made of structural steel, effectively closing the magnetic field
  • whose thickness reaches at least 10 mm
  • characterized by even structure
  • under conditions of no distance (surface-to-surface)
  • for force applied at a right angle (in the magnet axis)
  • at temperature approx. 20 degrees Celsius

Lifting capacity in practice – influencing factors

It is worth knowing that the magnet holding will differ subject to the following factors, starting with the most relevant:
  • Air gap (betwixt the magnet and the plate), as even a very small distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
  • Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
  • Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
  • Plate material – mild steel gives the best results. Alloy admixtures decrease magnetic permeability and holding force.
  • Surface condition – ground elements guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
  • Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the thermal limit for a given model.

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the holding force is lower. Additionally, even a small distance between the magnet and the plate reduces the load capacity.

Warnings
Finger safety

Danger of trauma: The pulling power is so immense that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

Medical interference

Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Powerful field

Exercise caution. Rare earth magnets act from a distance and snap with huge force, often quicker than you can react.

Magnets are brittle

Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Mechanical processing

Powder produced during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.

Safe distance

Device Safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, timepieces).

GPS Danger

Note: rare earth magnets produce a field that confuses precision electronics. Maintain a safe distance from your phone, device, and GPS.

Danger to the youngest

Product intended for adults. Tiny parts pose a choking risk, causing severe trauma. Keep out of reach of kids and pets.

Warning for allergy sufferers

Studies show that nickel (standard magnet coating) is a common allergen. If you have an allergy, refrain from direct skin contact or opt for versions in plastic housing.

Operating temperature

Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. Damage is permanent.
