Pulling power drops drastically with every subsequent millimeter of distance. Remember that even the smallest gap (e.g., contamination, varnish, rust) strongly reduces the pull force. Magnetic products operate strongest in perfect adhesion; distance nullifies the force. Notice how flashily the parameters drop, when the magnet does not touch flatly to the metal substrate. When planning the arrangement, eliminate unnecessary gaps.

Table 2: Slippage force (wall)

The table below calculates the estimated weight limit required to start the slippage of the magnet vertically along a upright metal surface (considering typical friction). This value varies with the air gap between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MP 5x2.7/1.2x5 Z / 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 hanging a element on a upright surface (e.g., a board), it you can count on just approx. 1/5 of nominal attraction strength. Gravity as well as a low friction coefficient influence the fact that holders slip easier than they pop off the substrate. Want to create a wall mount? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will slip down under a much lighter weight. Utilizing a rubberized pad can significantly improve the result.

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

A too thin steel is unable to absorb the entire magnetic field, which squanders power of the magnet. Should you install a neodymium to a weak sheet, the field will pass right through and the pull force will drop sharply. To achieve full efficiency of this neodymium's power, you need a suitably thick piece of steel. The material oversaturation means that on delicate walls (e.g., thin profiles), the holder works worse. We advise picking the steel dimension according to the table below.

Table 5: Working in heat (material behavior) - power drop
MP 5x2.7/1.2x5 Z / N38

Standard neodymium magnets irreversibly lose strength after exceeding the maximum temperature. Avoid high temperatures – high temperature can irreversibly destroy this product. With increasing heat, the magnet's power temporarily lowers. Do not use this magnet close to ovens exceeding its operating temperature limit. Ignoring the limit will cause irreversible degradation of magnetism.

*Engineering note: Temperature resistance is determined by both grade, as well as the dimension ratios. Thin magnets (pancake types) risk losing magnetic properties sooner compared to rod magnets. The danger warning in the table indicates permanent field degradation for this specific geometry.

Two strong neodymiums interact from a much further distance than a magnet and sheet setup. Such a system of magnet-to-magnet generates a stronger field and a further horizon of operation. Want to build a solid fastener? Apply two magnets instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the impact force is huge. The levitation is slightly lower than the connection force, but still impressive.
*Field value between like poles drops to ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
Important: Results demonstrate friction force of a pair of matching neodymium magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a serious hazard to IT equipment and pacemakers. These magnets produce a field that destroys function of digital equipment. Be aware: the invisible magnetic field passes through tissues and plastic. Exceptional care must be taken by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, car keys, membranes, and screens. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Table 8: Collisions (kinetic energy) - warning
MP 5x2.7/1.2x5 Z / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	33.26 km/h (9.24 m/s)	0.03 J
30 mm	57.59 km/h (16.00 m/s)	0.09 J
50 mm	74.35 km/h (20.65 m/s)	0.15 J
100 mm	105.14 km/h (29.21 m/s)	0.29 J

Magnetic elements are very brittle – a strong collision with metal causes immediate chipping. Watch the impact speed – a magnet released freely becomes dangerous. Kinetic force can trigger coating fragments or painful pinches to fingers. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Use safety goggles when playing with large magnets.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet holds just approx. 20-30% of its nominal pull.

2. Plate thickness effect

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

3. Power loss vs temp

*For N38 material, the safety 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.

The ring-shaped magnet MP 5x2.7/1.2x5 Z / N38 is created for permanent mounting, where glue might fail or be insufficient. Mounting is clean and reversible, unlike gluing. This product with a force of 0.75 kg works great as a cabinet closure, speaker holder, or spacer element in devices.

This is a crucial issue when working with model MP 5x2.7/1.2x5 Z / N38. Neodymium magnets are sintered ceramics, which means they are very brittle and inelastic. One turn too many can destroy the magnet, so do it slowly. 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 inside building use. For outdoor applications, we recommend choosing magnets in hermetic housing 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 key parameter here is the holding force amounting to approximately 0.75 kg (force ~7.31 N). The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 2.7/1.2 mm.

The poles are located on the planes with holes, not on the sides of the ring. 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.

Pros

Besides their high retention, neodymium magnets are valued for these benefits:

They virtually do not lose power, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
They are noted for resistance to demagnetization induced by external magnetic fields,
By using a shiny layer of gold, the element presents an modern look,
The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of detailed creating as well as optimizing to atypical needs,
Wide application in advanced technology sectors – they are utilized in mass storage devices, electric drive systems, precision medical tools, as well as other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which allows their use in compact constructions

Weaknesses

Disadvantages of NdFeB magnets:

To avoid cracks upon strong impacts, we recommend 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 force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
Limited possibility of creating nuts in the magnet and complicated forms - preferred is casing - magnetic holder.
Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, tiny parts of these magnets are able to complicate diagnosis medical in case of swallowing.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Pull force analysis

Best holding force of the magnet in ideal parameters – what affects it?

The specified lifting capacity represents the peak performance, recorded under ideal test conditions, specifically:

with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
possessing a massiveness of minimum 10 mm to avoid saturation
characterized by even structure
with direct contact (without impurities)
for force applied at a right angle (in the magnet axis)
in neutral thermal conditions

Lifting capacity in real conditions – factors

During everyday use, the actual holding force depends on several key aspects, presented from most significant:

Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
Direction of force – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
Chemical composition of the base – low-carbon steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
Surface structure – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.

Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the holding force is lower. In addition, even a slight gap between the magnet and the plate reduces the load capacity.

Warnings

Magnet fragility

Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Machining danger

Dust generated during cutting of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.

Implant safety

Patients with a ICD should keep an absolute distance from magnets. The magnetic field can stop the functioning of the implant.

Respect the power

Use magnets consciously. Their immense force can shock even experienced users. Plan your moves and do not underestimate their power.

Nickel coating and allergies

Some people experience a sensitization to nickel, which is the standard coating for NdFeB magnets. Extended handling might lead to an allergic reaction. We suggest wear safety gloves.

Finger safety

Big blocks can break fingers instantly. Do not put your hand betwixt two attracting surfaces.

Precision electronics

Note: rare earth magnets generate a field that interferes with sensitive sensors. Maintain a separation from your mobile, device, and GPS.

Data carriers

Avoid bringing magnets close to a wallet, computer, or screen. The magnetic field can destroy these devices and wipe information from cards.

Power loss in heat

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

Danger to the youngest

Adult use only. Tiny parts pose a choking risk, leading to intestinal necrosis. Store away from kids and pets.
