Pulling power weakens sharply with every mm of spacing. Remember that even a very thin break (e.g., dirt, paint, dust) significantly diminishes the holding power. Neodymiums work optimally at the point of direct contact; gap drastically cuts the force. Observe how flashily the pull force plummet, when the magnet does not adhere directly to the metal substrate. When calculating the assembly, eliminate redundant distances.

This section indicates the estimated weight limit needed to cause the downward movement of the magnet downwards against a upright steel plate (considering standard friction). This value varies with the gap size between the magnet and the surface.

When hanging a holder on a upright surface (e.g., a car body), it will only hold barely about 1/5 of its nominal power. Gravitational force and a low friction coefficient influence the fact that products slide down faster than they pull off. Designing a vertical fastening? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the magnet will slip down under a much lighter load. Utilizing a rubberized coating can effectively increase the grip.

A thin metal plate cannot focus the full magnetic flux, which wastes potential of the holder. Should you install a neodymium to a weak sheet, the flux will pass right through and the pull force will drop sharply. To utilize the maximum of this magnet's potential, you need a suitably thick piece of steel. The saturation effect means that on thin elements (e.g., thin profiles), the holder holds weaker. We recommend selecting the steel cross-section from these parameters.

Ordinary NdFeB products lose power above the temperature limit. Watch out for overheating – heat can permanently destroy this magnet. With every degree above norm, the magnet's force temporarily drops. Refrain from using this magnet in hot environments exceeding its working range. Ignoring the limit will result in permanent loss of magnetism.
*Technical advisory: Thermal stability is determined by both grade, but also on the magnet's shape. Flat magnets (low Pc) may lose charge permanently sooner than long magnets. Red status in the table points to a risk of irreversible loss for this particular item.

Two magnetic products interact from a much further distance than a magnet and steel combination. The setup of magnet-to-magnet produces a massive flux and a larger range of action. Planning to create a solid fastener? Use a pair of magnets instead of one magnet and a steel. Be careful that when connecting a pair of magnets, the pinch force is massive. The repulsion force is slightly lower than the attraction, but still significant.
*Field value between like poles reaches ~0 Gs at the geometric center between the magnets (due to field cancellation).
Attention: Estimates refer to sliding force of a pair of matching magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field poses a real danger to electronics and medical implants. These magnets generate a flux that destroys function of sensitive medical devices. Remember: the unseen radiation passes through tissues and glass. Increased vigilance must be taken by people with cochlear implants and drug dispensers. The risk also applies to: automatic timepieces, car keys, membranes, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

NdFeB products are prone to chipping – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Kinetic force can trigger coating fragments or dangerous crushing to skin. Hold the magnet firmly during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear safety glasses when handling with large magnets.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.
In water, the magnet feels stronger thanks to Archimedes' principle. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.
1. Vertical hold

*Caution: On a vertical surface, the magnet holds only a fraction of its max power.

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) severely limits the holding force.

3. Heat tolerance

*For standard magnets, the critical limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.28

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. The solid red line represents the demagnetization curve (material potential), while the dashed blue line is the load line based on the magnet's geometry. The Pc (Permeance Coefficient), also known as the load line slope, is a dimensionless value that describes the relationship between the magnet's shape and its magnetic stability. The intersection of these two lines (the black dot) is the operating point — it determines the actual magnetic flux density generated by the magnet in this specific configuration. A higher Pc value means the magnet is more 'slender' (tall relative to its area), resulting in a higher operating point and better resistance to irreversible demagnetization caused by external fields or temperature. A value of 0.42 is relatively low (typical for flat magnets), meaning the operating point is closer to the 'knee' of the curve — caution is advised when operating at temperatures near the maximum limit to avoid strength loss.

It is ideally suited for places where solid attachment of the magnet to the substrate is required without the risk of detachment. Thanks to the hole (often for a screw), this model enables easy screwing to wood, wall, plastic, or metal. This product with a force of 2.53 kg works great as a cabinet closure, speaker holder, or mounting element in devices.
This is a crucial issue when working with model MP 14x8/4x3 / N38. Neodymium magnets are sintered ceramics, which means they are very brittle and inelastic. When tightening the screw, you must maintain great sensitivity. We recommend tightening manually with a screwdriver, not an impact driver, because too much pressure will cause the ring to crack. The flat screw head should evenly press the magnet. Remember: cracking during assembly results from material properties, not a product defect.
Moisture can penetrate micro-cracks in the coating and cause oxidation of the magnet. Damage to the protective layer during assembly is the most common cause of rusting. If you must use it outside, paint it with anti-corrosion paint after mounting.
The inner hole diameter determines the maximum size of the mounting element. If the magnet does not have a chamfer (cone), we recommend using a screw with a flat or cylindrical head, or possibly using a washer. Always check that the screw head is not larger than the outer diameter of the magnet (14 mm), so it doesn't protrude beyond the outline.
It is a magnetic ring with a diameter of 14 mm and thickness 3 mm. The pulling force of this model is an impressive 2.53 kg, which translates to 24.85 N in newtons. The mounting hole diameter is precisely 8/4 mm.
The poles are located on the planes with holes, not on the sides of the ring. In the case of connecting two rings, make sure one is turned the right way. We do not offer paired sets with marked poles in this category, but they are easy to match manually.

Pros and cons of Nd2Fe14B magnets.

Benefits

Besides their durability, neodymium magnets are valued for these benefits:
  • They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
  • They have excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
  • The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
  • Magnets possess impressive magnetic induction on the outer side,
  • Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
  • Thanks to versatility in designing and the ability to adapt to client solutions,
  • Versatile presence in high-tech industry – they are used in computer drives, brushless drives, medical devices, also modern systems.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

What to avoid - cons of neodymium magnets: weaknesses and usage proposals
  • To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
  • When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in producing threads and complicated forms in magnets, we propose using casing - magnetic mount.
  • Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these devices can disrupt the diagnostic process medical after entering the body.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Magnetic strength at its maximum – what affects it?

The lifting capacity listed is a measurement result conducted under the following configuration:
  • using a plate made of low-carbon steel, functioning as a ideal flux conductor
  • with a cross-section of at least 10 mm
  • characterized by lack of roughness
  • with direct contact (without coatings)
  • for force acting at a right angle (in the magnet axis)
  • at ambient temperature approx. 20 degrees Celsius

Magnet lifting force in use – key factors

In real-world applications, the actual lifting capacity depends on a number of factors, presented from the most important:
  • Distance (betwixt the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
  • Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
  • Base massiveness – insufficiently thick plate causes magnetic saturation, causing part of the power to be escaped to the other side.
  • Metal type – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
  • Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
  • Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.

Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.

H&S for magnets
Fragile material

Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Allergy Warning

It is widely known that nickel (the usual finish) is a potent allergen. If you have an allergy, avoid direct skin contact and choose versions in plastic housing.

Keep away from children

Strictly keep magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are tragic.

Finger safety

Large magnets can break fingers instantly. Under no circumstances put your hand betwixt two strong magnets.

Data carriers

Equipment safety: Neodymium magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, mechanical watches).

Do not underestimate power

Be careful. Neodymium magnets attract from a long distance and connect with huge force, often quicker than you can move away.

Demagnetization risk

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

Medical interference

Medical warning: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.

Impact on smartphones

Navigation devices and smartphones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

Mechanical processing

Mechanical processing of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
