Grip strength drops significantly with every subsequent millimeter of distance. Keep in mind that every additional insulation layer (e.g., dirt, paint, dust) noticeably weakens the grip. Magnets work most effectively in perfect adhesion; air break weakens the force. Notice how flashily the load capacity fall, when the product does not touch directly to the metal substrate. When designing the assembly, avoid redundant distances.

The following data indicates the estimated force necessary to initiate the downward movement of the magnet vertically on a vertical steel plate (considering typical friction). The holding force varies with the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 25x10x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.25 kg / 4.95 lbs 2247.0 g / 22.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.50 kg / 3.30 lbs 1498.0 g / 14.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.75 kg / 1.65 lbs 749.0 g / 7.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.75 kg / 8.26 lbs 3745.0 g / 36.7 N

When mounting a magnet on a vertical plane (e.g., a car body), it will maintain barely approx. 20%-30% of nominal attraction strength. Gravitational force as well as a weak degree of grip influence the fact that products slide down easier than they pull off. Designing a vertical fastening? Consider that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the magnet will slide down under a significantly smaller cargo. Application of an anti-slip pad can effectively improve the result.

A too thin steel is unable to focus the full magnetic flux, which squanders power of the holder. If you attach a powerful product to a weak sheet, the flux will penetrate right through and the pull force will drop sharply. To squeeze full efficiency of this magnet's potential, you require a sufficiently solid element of steel. The saturation phenomenon causes that on thin elements (e.g., appliance housings), the product works worse. We advise picking the steel cross-section based on the following data.

Standard neodymium magnets change their properties parameters after exceeding the maximum temperature. Protect against heat – high temperature can permanently demagnetize this magnet. As the temperature rises, the magnet's capacity temporarily drops. Do not use this magnet in hot environments exceeding its operating temperature limit. Ignoring the limit will result in permanent loss of magnetic properties.

*Important note: Temperature resistance is determined by both grade, but also on the magnet's shape. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress than taller cylinders. Warning indicator in the table points to permanent field degradation for this particular item.

Two magnetic products interact from a wider radius than a magnet and sheet setup. Such a system of magnet-to-magnet creates a more powerful interaction and a wider radius of action. Planning to create a powerful holder? Apply two magnets instead of one magnet and a striker plate. Remember that when connecting a pair of magnets, the impact force is extreme. The levitation is slightly lower than the connection force, but still large.
*Field value in repulsion mode reaches ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Note: Results show friction force of a pair of same magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a real danger to electronics as well as medical implants. These neodymiums produce a field that prevents correct functioning of digital equipment. Notice: the unseen radiation acts through matter and glass. Special caution must be taken by people with hearing aids and drug dispensers. Influence will be felt by: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Magnetic elements are prone to chipping – a collision with steel can result in shattering. Watch the impact speed – a magnet released freely turns into a projectile. Striking energy can cause material chips or injury to fingers. Be sure to control the product during mounting so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear eye protection when playing with large magnets.

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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

*Caution: On a vertical wall, the magnet retains merely ~20% of its nominal pull.

2. Plate thickness effect

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

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.38

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.

This product is an extremely strong plate magnet made of NdFeB material, which, with dimensions of 25x10x5 mm and a weight of 9.38 g, guarantees premium class connection. This rectangular block with a force of 73.45 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 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 7.49 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 25x10x5 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 7.49 kg), they are ideal as closers in furniture making and mounting elements in automation. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 25x10x5 / 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 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 (25x10 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 25x10x5 mm, which, at a weight of 9.38 g, makes it an element with impressive energy density. The key parameter here is the lifting capacity amounting to approximately 7.49 kg (force ~73.45 N), which, with such a flat shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths as well as weaknesses of rare earth magnets.

Strengths

Besides their tremendous pulling force, neodymium magnets offer the following advantages:

They do not lose power, even over nearly ten years – the drop in lifting capacity is only ~1% (based on measurements),
Neodymium magnets are characterized by exceptionally resistant to magnetic field loss caused by external magnetic fields,
By applying a reflective coating of nickel, the element acquires an elegant look,
Magnetic induction on the top side of the magnet turns out to be extremely intense,
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 freedom in forming and the capacity to adapt to specific needs,
Wide application in high-tech industry – they are commonly used in computer drives, drive modules, precision medical tools, and complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in small systems

Disadvantages

Characteristics of disadvantages of neodymium magnets: tips and applications.

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also raises their durability
When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength 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
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Limited ability of producing threads in the magnet and complex shapes - recommended is casing - magnetic holder.
Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products can complicate diagnosis medical in case of swallowing.
Due to neodymium price, their price is higher than average,

Pull force analysis

Detachment force of the magnet in optimal conditions – what contributes to it?

Breakaway force is the result of a measurement for optimal configuration, assuming:

with the use of a sheet made of low-carbon steel, ensuring maximum field concentration
possessing a thickness of minimum 10 mm to ensure full flux closure
with an ideally smooth touching surface
under conditions of ideal adhesion (metal-to-metal)
under vertical application of breakaway force (90-degree angle)
in neutral thermal conditions

Determinants of lifting force in real conditions

Real force is influenced by working environment parameters, including (from most important):

Distance – the presence of any layer (rust, dirt, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of nominal force).
Steel thickness – insufficiently thick plate does not close the flux, causing part of the power to be lost to the other side.
Steel grade – the best choice is pure iron steel. Stainless steels may attract less.
Smoothness – ideal contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
Temperature – temperature increase results in weakening of induction. Check the thermal limit for a given model.

Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet and the plate reduces the holding force.

Safety rules for work with NdFeB magnets

Machining danger

Powder generated during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.

Danger to the youngest

Neodymium magnets are not suitable for play. Accidental ingestion of several magnets may result in them attracting across intestines, which poses a critical condition and requires immediate surgery.

Crushing force

Big blocks can crush fingers instantly. Never put your hand betwixt two strong magnets.

Nickel coating and allergies

A percentage of the population have a hypersensitivity to nickel, which is the common plating for neodymium magnets. Prolonged contact may cause skin redness. We suggest wear protective gloves.

Impact on smartphones

GPS units and mobile phones are extremely sensitive to magnetism. Direct contact with a strong magnet can permanently damage the sensors in your phone.

Risk of cracking

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

Medical interference

People with a heart stimulator have to keep an large gap from magnets. The magnetic field can disrupt the functioning of the implant.

Magnetic media

Equipment safety: Strong magnets can damage data carriers and delicate electronics (heart implants, medical aids, mechanical watches).

Conscious usage

Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

Heat sensitivity

Avoid heat. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
