Grip strength drops sharply per each millimeter of gap. Remember that every additional insulation layer (e.g., contamination, paint, dust) strongly reduces the pull force. Magnetic products hold most effectively during direct contact; distance kills the power. See how flashily the pull force fall, when the magnet does not touch flatly to the metal substrate. When designing the arrangement, eliminate unnecessary gaps.

The table below presents the theoretical shear load necessary to initiate the downward movement of the magnet down on a vertical metal surface (considering typical friction). The holding force is a function of the air gap between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MP 5x2.7/1.2x5 S / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.22 kg / 0.50 LBS 225.0 g / 2.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.33 LBS 150.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.17 LBS 75.0 g / 0.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.38 kg / 0.83 LBS 375.0 g / 3.7 N

When mounting a holder on a vertical plane (e.g., a car body), it you can count on only approx. 1/5 of its maximum pull force. Gravity and a weak degree of grip mean that holders slide down easier than they pull off. Designing a wall mount? Consider that the sliding force is much weaker than the maximum static pull force. On a painted metal, the holder will slip down under a much lighter cargo. Application of an anti-slip coating can significantly improve the result.

12 mm	100%	0.75 kg / 1.65 LBS 750.0 g / 7.4 N

A thin metal plate is unable to focus the entire magnetic field, which weakens actual performance of the holder. Should you install a neodymium to a weak sheet, the field will penetrate right through and the holding will be smaller. To utilize 100% of this neodymium's power, you require a sufficiently solid piece of steel. The saturation phenomenon means that on delicate walls (e.g., car bodies), the holder shows lower pull force. We advise picking the steel cross-section based on the following data.

Table 5: Thermal resistance (stability) - resistance threshold
MP 5x2.7/1.2x5 S / N38

Classic neodymiums change their properties power after exceeding the maximum temperature. Avoid high temperatures – high temperature can permanently destroy this product. With increasing heat, the magnet's capacity temporarily drops. Avoid using this product in hot environments exceeding its working range. Exceeding the critical threshold will lead to permanent loss of magnetic properties.

*Important note: Temperature resistance depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low Pc) risk losing magnetic properties under lower heat stress than long magnets. Warning indicator in the table points to permanent field degradation for this specific geometry.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and sheet setup. The connection of magnet-to-magnet produces a massive flux and a larger range of operation. Planning to create a solid fastener? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when bringing together two magnets, the collision energy is extreme. The levitation is a bit weaker than the connection force, but still large.
*Flux density for N-N configuration reaches ~0 Gs in the exact middle of the gap (resulting from vector opposition).
* Estimates demonstrate shear force of two same magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field is a real danger to electronic devices as well as pacemakers. These neodymiums generate a field that disrupts operation of digital equipment. Remember: the invisible magnetic field passes through tissues and housings. Exceptional care must be taken by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, remotes, speakers, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

NdFeB products are delicate – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Striking energy can trigger coating fragments or injury to fingers. Be sure to control the product during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Use safety goggles when playing with powerful specimens.

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Note: On a vertical surface, the magnet retains merely a fraction of its perpendicular strength.

2. Steel saturation

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

3. Thermal stability

*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) = 0.83

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.

It is ideally suited for places where solid attachment of the magnet to the substrate is required without the risk of detachment. Mounting is clean and reversible, unlike gluing. 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 5x2.7/1.2x5 S / 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 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. 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. 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 Ø5 mm (outer diameter) and height 5 mm. The pulling force of this model is an impressive 0.75 kg, which translates to 7.31 N in newtons. The mounting hole diameter is precisely 2.7/1.2 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 as well as weaknesses of Nd₂Fe₁₄B magnets.

Advantages

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

They do not lose magnetism, even during nearly ten years – the drop in strength is only ~1% (based on measurements),
They have excellent resistance to magnetic field loss due to opposing magnetic fields,
The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
Neodymium magnets achieve maximum magnetic induction on a contact point, which ensures high operational effectiveness,
Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures reaching 230°C and above...
Thanks to the option of free shaping and adaptation to unique needs, neodymium magnets can be modeled in a wide range of shapes and sizes, which expands the range of possible applications,
Universal use in electronics industry – they find application in computer drives, drive modules, medical devices, and complex engineering applications.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Disadvantages

Cons of neodymium magnets and proposals for their use:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Limited ability of creating threads in the magnet and complex shapes - preferred is cover - mounting mechanism.
Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these products are able to disrupt the diagnostic process 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

Highest magnetic holding force – what it depends on?

Magnet power was determined for the most favorable conditions, assuming:

on a base made of structural steel, optimally conducting the magnetic flux
with a thickness no less than 10 mm
characterized by smoothness
with zero gap (without paint)
under axial force direction (90-degree angle)
at standard ambient temperature

Lifting capacity in real conditions – factors

In real-world applications, the actual holding force results from many variables, ranked from the most important:

Clearance – the presence of any layer (rust, tape, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
Material type – the best choice is high-permeability steel. Cast iron may attract less.
Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
Thermal environment – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.

Lifting capacity was determined using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.

Warnings

Avoid contact if allergic

Medical facts indicate that nickel (the usual finish) is a common allergen. If you have an allergy, refrain from direct skin contact and opt for encased magnets.

Crushing risk

Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!

Electronic hazard

Do not bring magnets near a purse, laptop, or screen. The magnetic field can destroy these devices and wipe information from cards.

Machining danger

Fire hazard: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.

Life threat

People with a pacemaker have to maintain an large gap from magnets. The magnetism can interfere with the functioning of the life-saving device.

Beware of splinters

Beware of splinters. Magnets can explode upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.

Choking Hazard

Strictly store magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are life-threatening.

GPS Danger

Be aware: rare earth magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your mobile, tablet, and GPS.

Thermal limits

Regular neodymium magnets (N-type) lose power when the temperature goes above 80°C. Damage is permanent.

Conscious usage

Exercise caution. Neodymium magnets act from a long distance and snap with massive power, often quicker than you can move away.

Danger! Learn more about risks in the article: Magnet Safety Guide.
