Grip strength weakens significantly with every subsequent millimeter of gap. Note that every additional insulation layer (e.g., contamination, paint, rust) noticeably reduces the pull force. Neodymiums work optimally during direct contact; distance weakens the force. Observe how rapidly the parameters drop, when the magnet does not touch tightly to the steel surface. When planning the mounting, discard redundant distances.

This section indicates the estimated weight limit needed to initiate the downward movement of the magnet down against a upright steel wall (considering typical friction). The holding force depends on the separation distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MP 12x5x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.35 kg / 0.76 LBS 345.0 g / 3.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.23 kg / 0.51 LBS 230.0 g / 2.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.11 kg / 0.25 LBS 115.0 g / 1.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.58 kg / 1.27 LBS 575.0 g / 5.6 N

When mounting a magnet on a vertical surface (e.g., a fridge), it will maintain just about 20%-30% of its maximum pull force. Gravity and a low friction coefficient cause that magnets slide down easier than they pull off. Want to create a hanger? Note that the sliding force is much weaker than the maximum static pull force. On a painted metal, the holder will slide down under a much lighter cargo. Application of an anti-slip pad can effectively improve the result.

A too thin steel is not enough to take in the full magnetic flux, which wastes potential of the holder. If you mount a strong magnet to a weak sheet, the magnetism will penetrate right through and the attraction force will be weaker. To utilize full efficiency of this neodymium's power, you need a suitably thick element of steel. The saturation phenomenon means that on sheet metal structures (e.g., thin profiles), the holder shows lower pull force. We suggest choosing the steel cross-section according to the table below.

Classic neodymiums change their properties strength after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly demagnetize this magnet. As the temperature rises, the neodymium's capacity briefly lowers. Refrain from using this product near heat sources higher than its operating temperature limit. Ignoring the limit will cause permanent loss of magnetism.

*Engineering note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) are more susceptible to demagnetization sooner compared to rod magnets. Warning indicator in the table points to a risk of irreversible loss for this particular item.

Two magnets interact from a much further distance than a magnet and sheet setup. The setup of two magnets generates a stronger field and a larger range of operation. Planning to create a powerful holder? Apply two magnets instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the collision energy is huge. The repulsion force is marginally weaker than the attraction, but still large.
*Field value in repulsion mode drops to ~0 Gs at the midpoint of the gap (due to field cancellation).
* Calculations apply to sliding force of two same neodymium magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a large risk to electronics as well as medical implants. These magnets produce a flux that prevents correct functioning of digital equipment. Notice: the unseen radiation penetrates the body and glass. Special caution must be taken by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, car keys, speakers, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Magnetic elements are prone to chipping – a strong collision with metal risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Impact energy can trigger coating fragments or painful pinches to fingers. Be sure to control the product during bringing near metal so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear eye protection when playing with powerful specimens.

Warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

The magnetic field penetrates through water without any losses. 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 retains merely ~20% of its perpendicular strength.

2. Plate thickness effect

*Thin steel (e.g. computer case) severely reduces the holding force.

3. Power loss vs temp

*For N38 grade, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 1.34

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 P_c (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 P_c 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.

The ring magnet with a hole MP 12x5x2 / N38 is created for permanent mounting, where glue might fail or be insufficient. Thanks to the hole (often for a screw), this model enables easy screwing to wood, wall, plastic, or metal. It is also often used in advertising for fixing signs and in workshops for organizing tools.

This is a crucial issue when working with model MP 12x5x2 / N38. Neodymium magnets are sintered ceramics, which means they are hard but breakable and inelastic. When tightening the screw, you must maintain caution. We recommend tightening manually with a screwdriver, not an impact driver, because excessive force 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.

These magnets are coated with standard Ni-Cu-Ni plating, which protects them in indoor conditions, but is not sufficient for rain. In the place of the mounting hole, the coating is thinner and can be damaged when tightening the screw, which will become a corrosion focus. If you must use it outside, paint it with anti-corrosion paint after mounting.

A screw or bolt with a thread diameter smaller than 5 mm fits this model. For magnets with a straight hole, a conical head can act like a wedge and burst the magnet. Aesthetic mounting requires selecting the appropriate head size.

The presented product is a ring magnet with dimensions Ø12 mm (outer diameter) and height 2 mm. The key parameter here is the holding force amounting to approximately 1.15 kg (force ~11.29 N). The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 5 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.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Advantages

In addition to their long-term stability, neodymium magnets provide the following advantages:

Their magnetic field is maintained, and after approximately 10 years it drops only by ~1% (according to research),
They retain their magnetic properties even under external field action,
The use of an refined coating of noble metals (nickel, gold, silver) causes the element to look better,
Magnets are distinguished by exceptionally strong magnetic induction on the outer side,
Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
In view of the ability of accurate forming and adaptation to unique projects, NdFeB magnets can be modeled in a variety of forms and dimensions, which amplifies use scope,
Wide application in modern technologies – they are used in mass storage devices, brushless drives, advanced medical instruments, and modern systems.
Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Limitations

Disadvantages of neodymium magnets:

To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
Limited possibility of producing nuts in the magnet and complex forms - recommended is cover - mounting mechanism.
Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small components of these devices are able to complicate diagnosis medical after entering the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Pull force analysis

Magnetic strength at its maximum – what affects it?

Breakaway force is the result of a measurement for the most favorable conditions, taking into account:

on a block made of structural steel, effectively closing the magnetic field
whose thickness equals approx. 10 mm
characterized by lack of roughness
under conditions of no distance (surface-to-surface)
during pulling in a direction perpendicular to the mounting surface
at room temperature

Magnet lifting force in use – key factors

Real force is influenced by specific conditions, including (from priority):

Gap (between the magnet and the metal), because even a very small clearance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
Plate thickness – too thin sheet causes magnetic saturation, causing part of the flux to be lost to the other side.
Steel grade – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
Base smoothness – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was determined with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, however under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet’s surface and the plate decreases the holding force.

Precautions when working with NdFeB magnets

ICD Warning

People with a pacemaker should maintain an absolute distance from magnets. The magnetism can disrupt the functioning of the implant.

Powerful field

Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

Threat to electronics

Very strong magnetic fields can destroy records on credit cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.

Do not overheat magnets

Watch the temperature. Exposing the magnet to high heat will destroy its magnetic structure and strength.

Nickel allergy

Certain individuals have a sensitization to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact can result in a rash. We suggest wear protective gloves.

Dust explosion hazard

Drilling and cutting of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Magnet fragility

Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.

Serious injuries

Big blocks can crush fingers instantly. Never put your hand betwixt two strong magnets.

Swallowing risk

These products are not intended for children. Swallowing a few magnets may result in them attracting across intestines, which poses a direct threat to life and requires immediate surgery.

Compass and GPS

Navigation devices and smartphones are highly sensitive to magnetic fields. Direct contact with a strong magnet can ruin the sensors in your phone.
