Magnetic force drops sharply per each millimeter of spacing. Keep in mind that even a very thin break (e.g., contamination, paint, rust) significantly weakens the grip. Magnetic products work optimally in perfect adhesion; distance weakens the power. See how flashily the parameters fall, when the magnet does not touch tightly to the steel surface. When planning the assembly, avoid unnecessary gaps.

The table below indicates the approximate force needed to start the downward movement of the magnet vertically along a vertical metal surface (assuming typical friction). The holding force varies with the distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - vertical pull
MPL 5x5x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.23 kg / 0.51 LBS 231.0 g / 2.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.34 LBS 154.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.17 LBS 77.0 g / 0.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.39 kg / 0.85 LBS 385.0 g / 3.8 N

When placing a holder on a vertical surface (e.g., a board), it you can count on barely approx. 20%-30% of its nominal power. Gravity and a weak degree of grip cause that products slip faster than they pull off. Want to create a vertical fastening? Consider that the shear force is significantly lower than the maximum static pull force. On a slippery surface, the holder will give way down under a much lighter load. Using a rubber coating can effectively improve the result.

12 mm	100%	0.77 kg / 1.70 LBS 770.0 g / 7.6 N

A thin metal plate is incapable of absorb the full magnetic flux, which wastes potential of the holder. Should you mount a strong magnet to a thin surface, the flux will pass right through and the holding will be smaller. To utilize the maximum of this neodymium's potential, you require a sufficiently solid backing of metal. The material oversaturation causes that on delicate walls (e.g., thin profiles), the product works worse. We recommend selecting the steel cross-section from these parameters.

Classic neodymiums irreversibly lose parameters after exceeding the maximum temperature. Avoid high temperatures – high temperature can irreversibly destroy this magnet. As the temperature rises, the neodymium's power briefly drops. Avoid using this product close to heaters higher than its operating temperature limit. Ignoring the limit will cause destruction of magnetism.

*Technical advisory: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) are more susceptible to demagnetization sooner than taller cylinders. Warning indicator in the table indicates permanent field degradation for this specific geometry.

Two magnets interact from a significantly greater distance than a magnet and steel combination. The connection of magnet-to-magnet produces a massive flux and a wider radius of action. Designing a powerful holder? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when attracting two neodymiums, the impact force is massive. The repulsion force is slightly lower than the connection force, but still impressive.
*Flux density between like poles reaches ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Important: Figures show sliding force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a serious hazard to IT equipment as well as medical implants. These NdFeB products generate a field that disrupts operation of digital equipment. Notice: the invisible magnetic field passes through tissues and glass. Increased vigilance must be taken by people with hearing aids and drug dispensers. Influence will be felt by: mechanical watches, car keys, speakers, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Neodymium magnets are delicate – a violent impact against metal causes immediate chipping. Watch the impact speed – a neodymium left loose becomes dangerous. Kinetic force can trigger coating fragments or dangerous crushing to fingers. Hold the magnet firmly during installation so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear safety glasses when working with powerful specimens.

Corrosion warning: 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. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Caution: On a vertical surface, the magnet retains just approx. 20-30% of its perpendicular strength.

2. Efficiency vs thickness

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

3. Power loss vs temp

*For standard magnets, 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) = 0.46

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.

0.1845 ZŁ brutto / pcs

Model MPL 5x5x2 / N38 features a low profile and professional pulling force, making it an ideal solution for building separators and machines. As a magnetic bar with high power (approx. 0.77 kg), this product is available off-the-shelf from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. Watch your fingers! Magnets with a force of 0.77 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 5x5x2 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 0.77 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. 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 clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. In practice, this means that this magnet has the greatest attraction force on its main planes (5x5 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 5x5x2 mm, which, at a weight of 0.38 g, makes it an element with high energy density. It is a magnetic block with dimensions 5x5x2 mm and a self-weight of 0.38 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of rare earth magnets.

Advantages

Apart from their notable holding force, neodymium magnets have these key benefits:

They retain magnetic properties for almost 10 years – the drop is just ~1% (according to analyses),
They maintain their magnetic properties even under strong external field,
A magnet with a metallic nickel surface has better aesthetics,
Neodymium magnets deliver maximum magnetic induction on a small area, which ensures high operational effectiveness,
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...
Thanks to modularity in designing and the capacity to customize to unusual requirements,
Huge importance in future technologies – they are utilized in mass storage devices, motor assemblies, medical devices, and technologically advanced constructions.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

At strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's 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 and 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 usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
Due to limitations in realizing nuts and complicated forms in magnets, we propose using casing - magnetic mount.
Potential hazard resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child health protection. Furthermore, small elements of these devices can complicate diagnosis medical in case of swallowing.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Lifting parameters

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

Information about lifting capacity was defined for the most favorable conditions, including:

on a base made of mild steel, effectively closing the magnetic flux
with a cross-section no less than 10 mm
characterized by smoothness
under conditions of ideal adhesion (surface-to-surface)
under axial force direction (90-degree angle)
at temperature room level

Magnet lifting force in use – key factors

Holding efficiency is influenced by working environment parameters, such as (from priority):

Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet holds much less (typically approx. 20-30% of maximum force).
Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Material type – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
Smoothness – full contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.

Warnings

Heat sensitivity

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

Bodily injuries

Danger of trauma: The pulling power is so immense that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.

Do not give to children

These products are not toys. Swallowing a few magnets may result in them pinching intestinal walls, which poses a critical condition and necessitates immediate surgery.

Fragile material

Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Respect the power

Use magnets consciously. Their huge power can surprise even professionals. Stay alert and do not underestimate their power.

Combustion hazard

Powder produced during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Data carriers

Avoid bringing magnets near a purse, computer, or TV. The magnetic field can permanently damage these devices and wipe information from cards.

GPS Danger

Note: neodymium magnets generate a field that disrupts sensitive sensors. Keep a separation from your phone, tablet, and navigation systems.

Implant safety

Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.

Allergic reactions

Nickel alert: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, cease working with magnets and use protective gear.
