Magnetic force drops drastically per each millimeter of distance. Note that even a microscopic distance (e.g., contamination, varnish, rust) significantly weakens the grip. Magnets operate optimally during direct contact; distance kills the force. Observe how quickly the parameters plummet, when the magnet does not adhere tightly to the metal substrate. When designing the assembly, avoid additional spacers.

The following data presents the estimated holding capacity required to start the sliding of the magnet vertically on a upright metal surface (assuming typical friction). This parameter is a function of the distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull
MPL 40x10x4x2[7/3.5] / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.79 kg / 6.16 LBS 2793.0 g / 27.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.86 kg / 4.11 LBS 1862.0 g / 18.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.93 kg / 2.05 LBS 931.0 g / 9.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	4.66 kg / 10.26 LBS 4655.0 g / 45.7 N

When placing a holder on a vertical wall (e.g., a fridge), it you can count on barely about 1/5 of its nominal power. Gravitational force as well as a low friction coefficient influence the fact that magnets slip faster than they pull off. Designing a wall mount? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a smooth steel, the element will slip down under a significantly smaller cargo. Using a rubber layer can drastically raise the stability.

A thin metal plate is incapable of focus the entire magnetic field, which squanders power of the holder. Should you install a neodymium to a thin surface, the field will penetrate right through and the attraction force will be weaker. To achieve 100% of this magnet's power, you require a sufficiently solid backing of steel. The material oversaturation causes that on thin elements (e.g., thin profiles), the magnet works worse. We advise picking the steel thickness from these parameters.

Standard neodymium magnets irreversibly lose parameters after exceeding the maximum temperature. Watch out for overheating – heat can irreversibly demagnetize this product. With every degree above norm, the neodymium's capacity briefly lowers. Do not use this magnet in hot environments higher than its working range. Too high temperature will lead to permanent loss of magnetic properties.

*Important note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress compared to rod magnets. The danger warning in the table signals permanent field degradation for this specific geometry.

Two magnetic products interact from a significantly greater distance than a magnet and sheet combination. The connection of two magnets produces a massive flux and a further horizon of action. Designing a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when bringing together two magnets, the impact force is extreme. The levitation is a bit weaker than the connection force, but still significant.
*Flux density in repulsion mode drops to ~0 Gs at the geometric center between the magnets (due to field cancellation).
* Calculations demonstrate shear force of two same magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field is a serious hazard to electronics as well as pacemakers. These magnets produce a flux that disrupts operation of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and glass. Increased vigilance must be exercised by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, remotes, membranes, and screens. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Neodymium magnets are prone to chipping – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Striking energy can cause material chips or painful pinches to skin. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Use safety goggles when playing with powerful specimens.

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

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

1. Wall mount (shear)

*Caution: On a vertical surface, the magnet holds merely a fraction of its nominal pull.

2. Steel saturation

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

3. Heat tolerance

*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) = 0.26

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.

Model MPL 40x10x4x2[7/3.5] / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. This magnetic block with a force of 91.33 N is ready for shipment in 24h, allowing for rapid realization of your project. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

Separating strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 40x10x4x2[7/3.5] / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

They constitute a key element in the production of wind generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 40x10x4x2[7/3.5] / N38, it is best to use strong epoxy glues (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Remember to roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 40x10x4x2[7/3.5] / N38 model is magnetized through the thickness (dimension 4 mm), which means that the N and S poles are located on its largest, flat surfaces. In practice, this means that this magnet has the greatest attraction force on its main planes (40x10 mm), which is ideal for flat mounting. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

The presented product is a neodymium magnet with precisely defined parameters: 40 mm (length), 10 mm (width), and 4 mm (thickness). It is a magnetic block with dimensions 40x10x4 mm and a self-weight of 12 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths as well as weaknesses of rare earth magnets.

Advantages

Besides their exceptional strength, neodymium magnets offer the following advantages:

They have stable power, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
Neodymium magnets are exceptionally resistant to loss of magnetic properties caused by external magnetic fields,
By applying a decorative layer of silver, the element has an professional look,
Neodymium magnets deliver maximum magnetic induction on a contact point, which ensures high operational effectiveness,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
Considering the ability of accurate molding and adaptation to custom requirements, magnetic components can be produced in a broad palette of geometric configurations, which makes them more universal,
Huge importance in electronics industry – they are used in magnetic memories, motor assemblies, advanced medical instruments, also technologically advanced constructions.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:

To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in producing nuts and complex forms in magnets, we propose using a housing - magnetic mechanism.
Potential hazard resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the context of child safety. It is also worth noting that small components of these magnets can complicate diagnosis medical after entering the body.
With mass production the cost of neodymium magnets is a challenge,

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what affects it?

Breakaway force was determined for the most favorable conditions, taking into account:

with the application of a sheet made of special test steel, ensuring full magnetic saturation
with a thickness no less than 10 mm
characterized by even structure
under conditions of no distance (metal-to-metal)
during pulling in a direction vertical to the mounting surface
at ambient temperature approx. 20 degrees Celsius

Lifting capacity in practice – influencing factors

Please note that the application force may be lower influenced by the following factors, in order of importance:

Distance – existence of foreign body (rust, tape, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of nominal force).
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
Material composition – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
Base smoothness – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was determined using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate lowers the holding force.

Warnings

Thermal limits

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

Physical harm

Large magnets can crush fingers instantly. Never place your hand between two attracting surfaces.

Caution required

Handle magnets with awareness. Their powerful strength can shock even experienced users. Be vigilant and respect their power.

Dust explosion hazard

Fire hazard: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.

Material brittleness

Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Sensitization to coating

Certain individuals experience a contact allergy to nickel, which is the common plating for NdFeB magnets. Frequent touching may cause an allergic reaction. We suggest use protective gloves.

Protect data

Powerful magnetic fields can destroy records on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.

GPS Danger
