Pulling power drops significantly with every mm of gap. Note that every additional insulation layer (e.g., contamination, paint, veneer) strongly weakens the grip. Magnets work optimally at the point of direct contact; distance kills the force. Observe how quickly the load capacity plummet, when the magnet does not adhere directly to the metal substrate. When calculating the mounting, discard unnecessary gaps.

The table below presents the theoretical force necessary to initiate the shifting of the magnet vertically along a vertical steel plate (considering typical friction). This parameter depends on the gap size between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MPL 5x5x1 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.10 kg / 0.22 lbs 102.0 g / 1.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.07 kg / 0.15 lbs 68.0 g / 0.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.03 kg / 0.07 lbs 34.0 g / 0.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.17 kg / 0.37 lbs 170.0 g / 1.7 N

When hanging a magnet on a vertical plane (e.g., a fridge), it you can count on just about 20%-30% of its nominal power. Gravity as well as a low friction coefficient mean that holders slide down faster than they detach. Want to create a hanger? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the element will slip down under a noticeably lighter cargo. Application of an anti-slip coating can effectively raise the stability.

12 mm	100%	0.34 kg / 0.75 lbs 340.0 g / 3.3 N

A thin metal plate is incapable of conduct the full magnetic flux, which weakens actual performance of the magnet. Should you install a neodymium to a too thin substrate, the flux will pass right through and the pull force will drop sharply. To squeeze 100% of this magnet's power, you need a suitably thick backing of metal. The saturation effect causes that on delicate walls (e.g., appliance housings), the holder works worse. We suggest choosing the steel dimension based on the following data.

Table 5: Thermal stability (stability) - thermal limit

Classic neodymiums change their properties strength above the temperature limit. Protect against heat – high temperature can permanently damage this product. With every degree above norm, the magnet's power temporarily decreases. Refrain from using this magnet in hot environments higher than its working range. Ignoring the limit will lead to irreversible degradation of magnetism.

*Engineering note: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low Pc) risk losing magnetic properties at lower temperatures than taller cylinders. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a significantly greater distance than a magnet and sheet combination. The connection of magnet-to-magnet produces a massive flux and a wider radius of action. Planning to create a strong closure? Apply two magnets instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the collision energy is extreme. The repulsion force is slightly lower than the attraction, but still significant.
*Field value between like poles reaches ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Note: Estimates show sliding force of two matching magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field poses a serious hazard to IT equipment as well as medical implants. These magnets generate a flux that disrupts operation of sensitive medical devices. Remember: the invisible magnetic field acts through matter and glass. Exceptional care must be taken by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, remotes, speakers, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a strong collision with metal can result in shattering. Control the attraction moment – a neodymium left loose becomes dangerous. Kinetic force can destroy the magnet or painful pinches to skin. Be sure to control the product during bringing near metal so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear eye protection when working with powerful specimens.

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

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. Wall mount (shear)

*Caution: On a vertical surface, the magnet holds just ~20% of its max power.

2. Steel saturation

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

3. Temperature resistance

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.26

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.

This product is an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 5x5x1 mm and a weight of 0.19 g, guarantees the highest quality connection. This rectangular block with a force of 3.30 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 5x5x1 / 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 fasteners under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

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 5x5x1 mm, which, at a weight of 0.19 g, makes it an element with high energy density. It is a magnetic block with dimensions 5x5x1 mm and a self-weight of 0.19 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Strengths

Besides their tremendous field intensity, neodymium magnets offer the following advantages:

They have stable power, and over around 10 years their performance decreases symbolically – ~1% (in testing),
They maintain their magnetic properties even under close interference source,
Thanks to the glossy finish, the coating of Ni-Cu-Ni, gold, or silver-plated gives an aesthetic appearance,
They feature high magnetic induction at the operating surface, which improves attraction properties,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
Thanks to the ability of accurate molding and customization to unique needs, magnetic components can be modeled in a broad palette of geometric configurations, which amplifies use scope,
Key role in high-tech industry – they find application in data components, drive modules, medical devices, as well as modern systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in miniature devices

Weaknesses

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
Neodymium magnets lose their force 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 corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
We recommend cover - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex forms.
Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these magnets can disrupt the diagnostic process medical when they are in the body.
Due to expensive raw materials, their price is relatively high,

Lifting parameters

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

The force parameter is a theoretical maximum value conducted under the following configuration:

with the contact of a yoke made of low-carbon steel, ensuring maximum field concentration
with a cross-section no less than 10 mm
characterized by even structure
with zero gap (no paint)
during pulling in a direction perpendicular to the plane
at ambient temperature approx. 20 degrees Celsius

Lifting capacity in practice – influencing factors

In real-world applications, the actual holding force results from several key aspects, listed from the most important:

Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Chemical composition of the base – low-carbon steel attracts best. Alloy steels decrease magnetic properties and holding force.
Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
Temperature influence – hot environment weakens magnetic field. Too high temperature can permanently damage the magnet.

Lifting capacity was measured by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet and the plate decreases the lifting capacity.

H&S for magnets

Do not overheat magnets

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

Implant safety

Warning for patients: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or request help to work with the magnets.

Threat to electronics

Do not bring magnets close to a purse, laptop, or screen. The magnetic field can destroy these devices and wipe information from cards.

Nickel allergy

Studies show that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, prevent direct skin contact and opt for versions in plastic housing.

Safe operation

Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

Risk of cracking

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

Crushing force

Large magnets can crush fingers in a fraction of a second. Under no circumstances place your hand betwixt two strong magnets.

Product not for children

Neodymium magnets are not suitable for play. Eating multiple magnets can lead to them attracting across intestines, which poses a direct threat to life and necessitates urgent medical intervention.

Combustion hazard

Dust created during machining of magnets is combustible. Do not drill into magnets unless you are an expert.

Impact on smartphones

Remember: neodymium magnets generate a field that interferes with precision electronics. Keep a safe distance from your mobile, device, and navigation systems.
