Pulling power weakens significantly with every subsequent millimeter of gap. Keep in mind that even a very thin break (e.g., dirt, varnish, dust) strongly weakens the grip. Neodymiums operate strongest in perfect adhesion; air break kills the power. Notice how flashily the parameters plummet, when the product does not adhere tightly to the steel surface. When calculating the mounting, avoid unnecessary gaps.

This section shows the approximate weight limit sufficient to initiate the shifting of the magnet downwards on a vertical metal surface (assuming standard friction coefficient). This value varies with the gap size between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	7.28 kg / 16.05 lbs 7281.0 g / 71.4 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.85 kg / 10.70 lbs 4854.0 g / 47.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	2.43 kg / 5.35 lbs 2427.0 g / 23.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	12.14 kg / 26.75 lbs 12135.0 g / 119.0 N

When hanging a element on a vertical surface (e.g., a board), it will maintain only about 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip cause that holders move down faster than they detach. Planning a hanger? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a slippery surface, the magnet will slip down under a much lighter cargo. Using a rubber pad can effectively increase the grip.

A too thin steel is not enough to conduct the full magnetic flux, which weakens actual performance of the holder. Should you attach a powerful product to a too thin substrate, the flux will pass right through and the holding will be smaller. To utilize the maximum of this neodymium's potential, you need a suitably thick backing of metal. The saturation effect causes that on delicate walls (e.g., car bodies), the product shows lower pull force. We suggest choosing the steel thickness based on the following data.

Classic neodymiums irreversibly lose parameters above the temperature limit. Avoid high temperatures – heat can irreversibly damage this product. As the temperature rises, the neodymium's capacity briefly lowers. Avoid using this magnet near heat sources higher than its operating temperature limit. Too high temperature will result in permanent loss of magnetic properties.

*Important note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Thin magnets (pancake types) may lose charge permanently under lower heat stress than long magnets. The danger warning in the table signals permanent field degradation for this particular item.

Two magnetic products attract each other from a significantly greater distance than a neodymium and metal combination. Such a system of magnet-to-magnet produces a massive flux and a wider radius of action. Want to build a strong closure? Utilize two neodymiums instead of a neodymium and a striker plate. Exercise caution that when attracting two neodymiums, the impact force is huge. The repulsion force is slightly lower than the attraction, but still significant.
*Flux density in repulsion mode is approximately ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Attention: Estimates demonstrate shear force of dual identical neodymium magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field poses a large risk to electronic devices as well as pacemakers. These neodymiums generate a field that disrupts operation of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and glass. Special caution must be taken by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, remotes, speakers, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Neodymium magnets are delicate – a strong collision with metal can result in shattering. Control the attraction moment – a magnet released freely becomes dangerous. Striking energy can destroy the magnet or injury to fingers. Be sure to control the product during bringing near metal 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 handling with large magnets.

Corrosion warning: 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. Buoyancy helps in lifting finds.

1. Wall mount (shear)

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

2. Steel saturation

*Thin steel (e.g. 0.5mm PC case) severely limits the holding force.

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.74

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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 magnet in the shape of a plate made of NdFeB material, which, with dimensions of 30x20x20 mm and a weight of 90 g, guarantees premium class connection. This magnetic block with a force of 238.07 N is ready for shipment in 24h, allowing for rapid realization of your project. Furthermore, its Ni-Cu-Ni coating secures 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 24.27 kg can pinch very hard and cause hematomas. 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. Thanks to the flat surface and high force (approx. 24.27 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. 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. 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. In practice, this means that this magnet has the greatest attraction force on its main planes (30x20 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

The presented product is a neodymium magnet with precisely defined parameters: 30 mm (length), 20 mm (width), and 20 mm (thickness). The key parameter here is the holding force amounting to approximately 24.27 kg (force ~238.07 N), which, with such a flat shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Advantages as well as disadvantages of rare earth magnets.

Strengths

Apart from their consistent magnetism, neodymium magnets have these key benefits:

They retain full power for almost ten years – the drop is just ~1% (in theory),
They maintain their magnetic properties even under close interference source,
By using a reflective coating of silver, the element acquires an elegant look,
Neodymium magnets achieve maximum magnetic induction on a small surface, which increases force concentration,
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 forming and the ability to modify to complex applications,
Universal use in innovative solutions – they are used in mass storage devices, electromotive mechanisms, medical equipment, as well as other advanced devices.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Cons

Cons of neodymium magnets and ways of using them

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
Due to limitations in realizing nuts and complicated forms in magnets, we recommend using a housing - magnetic mount.
Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products can be problematic in diagnostics medical after entering the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

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

The specified lifting capacity concerns the maximum value, obtained under optimal environment, namely:

with the contact of a yoke made of special test steel, guaranteeing maximum field concentration
with a cross-section of at least 10 mm
with a plane free of scratches
under conditions of ideal adhesion (surface-to-surface)
during pulling in a direction perpendicular to the mounting surface
at ambient temperature approx. 20 degrees Celsius

Practical lifting capacity: influencing factors

It is worth knowing that the magnet holding may be lower depending on elements below, in order of importance:

Distance – the presence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Chemical composition of the base – mild steel gives the best results. Alloy admixtures reduce magnetic properties and lifting capacity.
Surface condition – ground elements guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
Heat – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).

Holding force was measured 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. Moreover, even a small distance between the magnet and the plate lowers the load capacity.

Precautions when working with neodymium magnets

Magnet fragility

Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Electronic hazard

Powerful magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.

Serious injuries

Danger of trauma: The pulling power is so great that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.

Pacemakers

Individuals with a ICD have to keep an large gap from magnets. The magnetic field can interfere with the functioning of the implant.

Do not give to children

Neodymium magnets are not suitable for play. Eating a few magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and requires urgent medical intervention.

Sensitization to coating

Studies show that nickel (standard magnet coating) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands or opt for encased magnets.

Flammability

Dust created during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Maximum temperature

Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its properties and strength.

Safe operation

Handle with care. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can react.

Threat to navigation

A powerful magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets near a device to avoid breaking the sensors.
