Pulling power decreases sharply with every subsequent millimeter of distance. Keep in mind that every additional insulation layer (e.g., dirt, paint, veneer) noticeably diminishes the holding power. Neodymiums work most effectively at the point of direct contact; distance kills the power. Notice how flashily the parameters fall, when the product does not adhere flatly to the steel surface. When planning the arrangement, eliminate additional spacers.

The following data indicates the estimated holding capacity needed to cause the sliding of the magnet downwards against a vertical metal surface (considering typical friction). The holding force is a function of the gap size between the magnet and the metal.

Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.24 kg / 2.74 lbs 1242.0 g / 12.2 N

When hanging a holder on a vertical surface (e.g., a car body), it will only hold barely about 1/5 of its maximum pull force. Gravitational force as well as a weak degree of grip influence the fact that products slide down faster than they detach. Want to create a wall mount? Note that the sliding force is much weaker than the perpendicular breakaway force. On a smooth steel, the magnet will slide down under a significantly smaller weight. Using a rubber pad can significantly improve the result.

A too thin steel is not enough to absorb the entire magnetic field, which squanders power of the holder. Should you attach a powerful product to a too thin substrate, the field will pass right through and the holding will be smaller. To utilize full efficiency of this magnet's power, you require a sufficiently solid piece of metal. The material oversaturation means that on thin elements (e.g., thin profiles), the magnet works worse. We recommend selecting the steel dimension based on the following data.

Standard neodymium magnets irreversibly lose parameters after exceeding the maximum temperature. Protect against heat – high temperature can permanently damage this product. With increasing heat, the neodymium's capacity temporarily lowers. Do not use this product in hot environments exceeding its operating temperature limit. Too high temperature will result in destruction of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) may lose charge permanently at lower temperatures compared to rod magnets. Red status in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a wider radius than a neodymium and metal combination. The setup of magnet-to-magnet produces a massive flux and a wider radius of performance. Designing a powerful holder? Use a pair of magnets instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the impact force is massive. The levitation is marginally weaker than the connection force, but still significant.
*Field value between like poles is approximately ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Important: Figures show shear force of two identical magnets (friction ~0.15 for Ni-Ni plating).

Table 7: Hazards (electronics) - precautionary measures

A strong magnetic field poses a large risk to IT equipment as well as pacemakers. These NdFeB products produce a field that prevents correct functioning of digital equipment. Notice: the invisible magnetic field acts through matter and housings. Special caution must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, car keys, membranes, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Dynamics (kinetic energy) - warning
MPL 35x7x3 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	34.12 km/h (9.48 m/s)	0.25 J
30 mm	58.65 km/h (16.29 m/s)	0.73 J
50 mm	75.71 km/h (21.03 m/s)	1.22 J
100 mm	107.07 km/h (29.74 m/s)	2.44 J

NdFeB products are prone to chipping – a strong collision with metal can result in shattering. Watch the impact speed – a neodymium left loose speeds with massive force. Striking energy can cause material chips or painful pinches to fingers. Be sure to control the product during mounting so it doesn't hit with great force against the metal. A collision at high speed ends with a crack of the neodymium. Wear eye protection when playing with large magnets.

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

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Vertical hold

*Caution: On a vertical wall, the magnet retains only approx. 20-30% of its max power.

2. Steel thickness impact

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

3. Heat tolerance

*For N38 material, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.25

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 a very powerful plate magnet made of NdFeB material, which, with dimensions of 35x7x3 mm and a weight of 5.51 g, guarantees the highest quality connection. As a block magnet with high power (approx. 6.21 kg), this product is available off-the-shelf from our warehouse in Poland. Furthermore, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

The key to success is sliding the magnets along their largest connection plane (using e.g., the edge of a table), which is easier than trying to tear them apart directly. Watch your fingers! Magnets with a force of 6.21 kg can pinch very hard and cause hematomas. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

They constitute a key element in the production of generators and material handling systems. Thanks to the flat surface and high force (approx. 6.21 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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

This model is characterized by dimensions 35x7x3 mm, which, at a weight of 5.51 g, makes it an element with high energy density. The key parameter here is the lifting capacity amounting to approximately 6.21 kg (force ~60.89 N), which, with such a compact shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Pros and cons of neodymium magnets.

Advantages

In addition to their long-term stability, neodymium magnets provide the following advantages:

They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
They do not lose their magnetic properties even under external field action,
In other words, due to the aesthetic finish of nickel, the element is aesthetically pleasing,
They show high magnetic induction at the operating surface, which increases their power,
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 versatility in forming and the ability to adapt to individual projects,
Wide application in advanced technology sectors – they serve a role in hard drives, drive modules, medical devices, and other advanced devices.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets decrease their power 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 rust. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Limited possibility of creating nuts in the magnet and complicated shapes - preferred is casing - mounting mechanism.
Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these magnets can complicate diagnosis medical after entering the body.
With budget limitations the cost of neodymium magnets is a challenge,

Holding force characteristics

Detachment force of the magnet in optimal conditions – what it depends on?

The load parameter shown refers to the limit force, recorded under ideal test conditions, meaning:

using a base made of high-permeability steel, acting as a magnetic yoke
possessing a massiveness of minimum 10 mm to avoid saturation
characterized by smoothness
under conditions of ideal adhesion (metal-to-metal)
for force acting at a right angle (pull-off, not shear)
at conditions approx. 20°C

Impact of factors on magnetic holding capacity in practice

In practice, the actual holding force results from several key aspects, listed from the most important:

Air gap (betwixt the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
Base massiveness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be escaped into the air.
Metal type – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
Smoothness – full contact is obtained only on polished steel. Rough texture reduce the real contact area, reducing force.
Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was assessed using a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.

Precautions when working with NdFeB magnets

Finger safety

Big blocks can crush fingers in a fraction of a second. Never put your hand betwixt two attracting surfaces.

Implant safety

People with a ICD should keep an safe separation from magnets. The magnetism can disrupt the operation of the implant.

Allergic reactions

Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, immediately stop working with magnets and use protective gear.

Flammability

Powder produced during cutting of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.

Risk of cracking

Protect your eyes. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.

Danger to the youngest

Only for adults. Small elements can be swallowed, causing serious injuries. Keep away from kids and pets.

Do not overheat magnets

Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its properties and strength.

Keep away from computers

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

Impact on smartphones

An intense magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Maintain magnets close to a smartphone to avoid damaging the sensors.

Do not underestimate power

Use magnets consciously. Their huge power can shock even professionals. Plan your moves and respect their force.
