Grip strength weakens sharply with every subsequent millimeter of spacing. Keep in mind that even the smallest gap (e.g., dirt, varnish, rust) strongly reduces the pull force. Neodymiums operate strongest during direct contact; distance kills the force. Analyze how rapidly the load capacity plummet, when the product does not adhere directly to the metal substrate. When calculating the arrangement, discard unnecessary gaps.

The following data shows the theoretical force required to start the shifting of the magnet vertically against a vertical metal surface (considering standard friction). This parameter is a function of the distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
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 placing a holder on a vertical plane (e.g., a board), it will only hold just approx. 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip influence the fact that holders slip faster than they pull off. Want to create a wall mount? Remember that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the magnet will give way down under a much lighter cargo. Using a rubber layer can significantly increase the grip.

A thin sheet is not enough to take in the entire magnetic field, which wastes potential of the magnet. If you mount a strong magnet to a thin surface, the field will penetrate right through and the holding will be smaller. To utilize 100% of this magnet's power, you need a suitably thick element of metal. The material oversaturation means that on sheet metal structures (e.g., appliance housings), the holder holds weaker. We suggest choosing the steel thickness according to the table below.

Classic neodymiums lose parameters past the thermal threshold. Avoid high temperatures – excessive heat can irreversibly demagnetize this magnet. As the temperature rises, the magnet's capacity temporarily lowers. Avoid using this product close to ovens higher than its working range. Exceeding the critical threshold will result in permanent loss of magnetic properties.

*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Thin magnets (pancake types) risk losing magnetic properties at lower temperatures compared to rod magnets. The danger warning in the table signals permanent field degradation for this specific geometry.

Two magnetic products attract each other from a wider radius than a neodymium and metal combination. Such a system of magnet-to-magnet generates a stronger field and a larger range of operation. Designing a solid fastener? Utilize two neodymiums instead of one magnet and a steel. Remember that when attracting two neodymiums, the impact force is huge. The repulsion force is marginally weaker than the attraction, but still impressive.
*Flux density between like poles is approximately ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Note: Estimates demonstrate friction force of two identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a real danger to electronic devices and pacemakers. These magnets produce a field that disrupts operation of digital equipment. Remember: the unseen radiation penetrates the body and housings. Exceptional care must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, car keys, membranes, and screens. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Neodymium magnets are very brittle – a collision with steel risks their cracking. Control the attraction moment – a neodymium left loose turns into a projectile. Striking energy can destroy the magnet or dangerous crushing to skin. Always hold the magnet during mounting so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear safety glasses when working with large magnets.

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Shear force

*Caution: On a vertical surface, the magnet holds just ~20% of its nominal pull.

2. Plate thickness effect

*Thin steel (e.g. computer case) drastically limits the holding force.

3. Thermal stability

*For N38 material, 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 quick installation to wood, wall, plastic, or metal. It is also often used in advertising for fixing signs and in workshops for organizing tools.

This material behaves more like porcelain than steel, so it doesn't forgive mistakes during mounting. 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. Damage to the protective layer during assembly is the most common cause of rusting. This product is dedicated for indoor use. For outdoor applications, we recommend choosing rubberized holders or additional protection with varnish.

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 (12 mm), so it doesn't protrude beyond the outline.

The presented product is a ring magnet with dimensions Ø12 mm (outer diameter) and height 2 mm. The key parameter here is the lifting capacity 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.

Advantages and disadvantages of neodymium magnets.

Strengths

Besides their exceptional pulling force, neodymium magnets offer the following advantages:

They have unchanged lifting capacity, and over more than ten years their performance decreases symbolically – ~1% (in testing),
Neodymium magnets are extremely resistant to demagnetization caused by magnetic disturbances,
The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to present itself better,
Magnetic induction on the surface of the magnet is very high,
Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
Thanks to the potential of accurate shaping and adaptation to specialized solutions, NdFeB magnets can be created in a variety of shapes and sizes, which amplifies use scope,
Versatile presence in innovative solutions – they are commonly used in computer drives, motor assemblies, medical devices, as well as industrial machines.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in small systems

Weaknesses

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as 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
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
We suggest casing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complex shapes.
Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. It is also worth noting that small components of these products are able to disrupt the diagnostic process medical when they are in the body.
With large orders the cost of neodymium magnets can be a barrier,

Lifting parameters

Maximum lifting force for a neodymium magnet – what it depends on?

Holding force of 1.15 kg is a measurement result conducted under the following configuration:

with the contact of a yoke made of special test steel, guaranteeing maximum field concentration
whose transverse dimension reaches at least 10 mm
with a surface cleaned and smooth
without the slightest clearance between the magnet and steel
for force applied at a right angle (in the magnet axis)
in neutral thermal conditions

Practical aspects of lifting capacity – factors

Holding efficiency is affected by working environment parameters, such as (from most important):

Distance – existence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Steel grade – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
Smoothness – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Thermal environment – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.

H&S for magnets

Magnetic media

Data protection: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, timepieces).

Avoid contact if allergic

Certain individuals experience a sensitization to Ni, which is the standard coating for NdFeB magnets. Extended handling can result in dermatitis. We strongly advise use protective gloves.

Beware of splinters

Beware of splinters. Magnets can fracture upon violent connection, ejecting shards into the air. We recommend safety glasses.

Flammability

Drilling and cutting of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Keep away from children

Always store magnets away from children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are life-threatening.

Medical implants

For implant holders: Strong magnetic fields disrupt medical devices. Maintain at least 30 cm distance or request help to handle the magnets.

Heat warning

Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.

Serious injuries

Large magnets can crush fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.

Compass and GPS

A powerful magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Keep magnets near a smartphone to avoid damaging the sensors.

Conscious usage

Be careful. Rare earth magnets act from a long distance and connect with huge force, often quicker than you can react.
