Grip strength weakens significantly with every mm of gap. Remember that even a very thin break (e.g., contamination, paint, veneer) noticeably reduces the pull force. Magnetic products work optimally during direct contact; air break drastically cuts the power. See how quickly the parameters fall, when the magnet does not adhere tightly to the steel surface. When planning the assembly, discard unnecessary gaps.

The following data calculates the estimated shear load needed to start the shifting of the magnet downwards against a vertical steel wall (assuming standard friction). This parameter varies with the air gap between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MP 12x8/4x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.66 kg / 663.0 g 6.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.44 kg / 442.0 g 4.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.22 kg / 221.0 g 2.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.11 kg / 1105.0 g 10.8 N

When hanging a element on a upright wall (e.g., a fridge), it will maintain just about 1/5 of its nominal power. Gravity and a weak degree of grip cause that products slide down faster than they pull off. Planning a vertical fastening? Remember that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the holder will slip down under a much lighter cargo. Using a rubber layer can effectively improve the result.

Table 4: Material efficiency (substrate influence) - power losses
MP 12x8/4x3 / N38

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	10%	0.22 kg / 221.0 g 2.2 N
1 mm	25%	0.55 kg / 552.5 g 5.4 N
2 mm	50%	1.11 kg / 1105.0 g 10.8 N
5 mm	100%	2.21 kg / 2210.0 g 21.7 N
10 mm	100%	2.21 kg / 2210.0 g 21.7 N

A too thin steel is not enough to absorb the entire magnetic field, which squanders power of the holder. If you attach a powerful product to a weak sheet, the flux will pass right through and the holding will be smaller. To utilize 100% of this magnet's power, you need a suitably thick piece of steel. The material oversaturation causes that on sheet metal structures (e.g., appliance housings), the holder works worse. We recommend selecting the steel thickness based on the following data.

Table 5: Thermal resistance (stability) - resistance threshold
MP 12x8/4x3 / N38

Ambient temp. (°C)	Power loss	Remaining pull	Status
20 °C	0.0%	2.21 kg / 2210.0 g 21.7 N	OK
40 °C	-2.2%	2.16 kg / 2161.4 g 21.2 N	OK
60 °C	-4.4%	2.11 kg / 2112.8 g 20.7 N
80 °C	-6.6%	2.06 kg / 2064.1 g 20.2 N
100 °C	-28.8%	1.57 kg / 1573.5 g 15.4 N

Standard neodymium magnets irreversibly lose strength past the thermal threshold. Watch out for overheating – heat can irreversibly demagnetize this magnet. With increasing heat, the magnet's capacity momentarily decreases. Do not use this magnet near heat sources higher than its safe range. Exceeding the critical threshold will result in destruction of magnetism.

*Engineering note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) may lose charge permanently under lower heat stress than taller cylinders. The danger warning in the table signals a risk of irreversible loss for this specific geometry.

Two magnets interact from a much further distance than a neodymium and metal setup. Such a system of two magnets produces a massive flux and a further horizon of performance. Want to build a strong closure? Utilize two neodymiums instead of one magnet and a steel. Remember that when connecting a pair of magnets, the impact force is extreme. The levitation is slightly lower than the attraction, but still impressive.
*The magnetic induction for N-N configuration is approximately ~0 Gs at the midpoint of the gap (due to field cancellation).

Table 7: Protective zones (implants) - precautionary measures

A strong magnetic field is a serious hazard to IT equipment and medical implants. These neodymiums produce a field that destroys function of sensitive medical devices. Be aware: the unseen radiation acts through matter and plastic. Exceptional care must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, remotes, speakers, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Neodymium magnets are very brittle – a violent impact against metal can result in shattering. Watch the impact speed – a magnet released freely speeds with massive force. Striking energy can trigger coating fragments or painful pinches to skin. Hold the magnet firmly during installation so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear eye protection when working with powerful specimens.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

Water displaces steel, making heavy objects slightly lighter. Buoyancy helps in lifting finds.

1. Sliding resistance

*Note: On a vertical wall, the magnet holds only approx. 20-30% of its perpendicular strength.

2. Steel saturation

*Thin metal sheet (e.g. computer case) significantly weakens the holding force.

3. Temperature resistance

*For N38 grade, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.32

This simulation demonstrates the magnetic stability of the selected magnet under specific geometric conditions. 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-shaped magnet MP 12x8/4x3 / N38 is created for mechanical fastening, where glue might fail or be insufficient. Mounting is clean and reversible, unlike gluing. 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 great sensitivity. 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.

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. Aesthetic mounting requires selecting the appropriate head size.

The presented product is a ring magnet with dimensions Ø12 mm (outer diameter) and height 3 mm. The key parameter here is the lifting capacity amounting to approximately 2.21 kg (force ~21.72 N). The mounting hole diameter is precisely 8/4 mm.

These magnets are magnetized axially (through the thickness), which means one flat side is the N pole and the other is S. If you want two such magnets screwed with cones facing each other (faces) to attract, you must connect them with opposite poles (N to S). 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

Besides their durability, neodymium magnets are valued for these benefits:

They retain full power for almost 10 years – the drop is just ~1% (based on simulations),
They do not lose their magnetic properties even under close interference source,
By using a shiny coating of nickel, the element gains an elegant look,
The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Due to the option of free shaping and adaptation to specialized solutions, magnetic components can be modeled in a variety of forms and dimensions, which expands the range of possible applications,
Versatile presence in innovative solutions – they are utilized in data components, electric drive systems, medical devices, as well as other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in miniature devices

Disadvantages

Drawbacks and weaknesses of neodymium magnets: application proposals

To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 extremely resistant to heat
They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in realizing threads and complicated shapes in magnets, we recommend using casing - magnetic holder.
Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Additionally, small elements of these products are able to complicate diagnosis medical when they are in the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

Highest magnetic holding force – what it depends on?

The declared magnet strength refers to the peak performance, measured under optimal environment, namely:

on a plate made of structural steel, optimally conducting the magnetic field
possessing a massiveness of min. 10 mm to ensure full flux closure
with a plane perfectly flat
with direct contact (without coatings)
under axial force vector (90-degree angle)
in stable room temperature

Lifting capacity in real conditions – factors

Bear in mind that the application force will differ subject to elements below, in order of importance:

Clearance – existence of foreign body (rust, tape, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of nominal force).
Base massiveness – too thin sheet does not close the flux, causing part of the flux to be escaped into the air.
Material type – the best choice is pure iron steel. Hardened steels may attract less.
Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
Temperature influence – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

Safety rules for work with neodymium magnets

Magnetic media

Intense magnetic fields can destroy records on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.

Protective goggles

Neodymium magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets will cause them shattering into small pieces.

Handling rules

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

Pinching danger

Watch your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!

GPS Danger

A strong magnetic field negatively affects the operation of magnetometers in smartphones and navigation systems. Maintain magnets close to a device to avoid damaging the sensors.

Do not give to children

NdFeB magnets are not suitable for play. Eating a few magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and necessitates immediate surgery.

Do not drill into magnets

Machining of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Permanent damage

Monitor thermal conditions. Heating the magnet to high heat will destroy its properties and strength.

Allergic reactions

Certain individuals have a sensitization to Ni, which is the common plating for neodymium magnets. Frequent touching might lead to skin redness. We strongly advise wear protective gloves.

Life threat

People with a pacemaker have to keep an absolute distance from magnets. The magnetic field can disrupt the operation of the implant.
