Grip strength decreases drastically per each millimeter of spacing. Remember that even a microscopic distance (e.g., contamination, paint, rust) noticeably reduces the pull force. Neodymiums hold most effectively in perfect adhesion; air break kills the force. Observe how flashily the pull force plummet, when the product does not adhere tightly to the metal substrate. When designing the arrangement, avoid additional spacers.

The following data shows the theoretical shear load required to cause the downward movement of the magnet downwards against a upright steel plate (assuming standard friction coefficient). This parameter depends on the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 40x18x10 SH / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	7.14 kg / 15.75 lbs 7143.0 g / 70.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.76 kg / 10.50 lbs 4762.0 g / 46.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	2.38 kg / 5.25 lbs 2381.0 g / 23.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	11.91 kg / 26.25 lbs 11905.0 g / 116.8 N

When placing a element on a upright surface (e.g., a board), it will maintain barely about 20%-30% of its maximum pull force. Gravity as well as a weak degree of grip mean that products slip easier than they detach. Want to create a vertical fastening? Consider that the shear force is noticeably lower than the maximum static pull force. On a slippery surface, the magnet will give way down under a much lighter weight. Application of an anti-slip coating can effectively increase the grip.

12 mm	100%	23.81 kg / 52.49 lbs 23810.0 g / 233.6 N

A too thin steel cannot focus the full magnetic flux, which wastes potential of the holder. If you install a neodymium to a too thin substrate, the flux will pass right through and the holding will be smaller. To squeeze full efficiency of this neodymium's power, you require a sufficiently solid element of metal. The saturation phenomenon means that on thin elements (e.g., car bodies), the holder holds weaker. We recommend selecting the steel thickness from these parameters.

Ordinary NdFeB products lose strength past the thermal threshold. Protect against heat – high temperature can irreversibly damage this product. With increasing heat, the magnet's power temporarily decreases. Avoid using this product close to heaters higher than its safe range. Too high temperature will cause destruction of magnetic properties.

*Engineering note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress than long magnets. Warning indicator in the table points to permanent field degradation for this specific geometry.

Two magnets attract each other from a much further distance than a magnet and steel setup. The setup of magnet-to-magnet generates a stronger field and a wider radius of operation. Designing a solid fastener? Apply two magnets instead of one magnet and a steel. Be careful that when bringing together two magnets, the pinch force is extreme. The levitation is marginally weaker than the attraction, but still significant.
*The magnetic induction in repulsion mode is approximately ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
* Calculations show shear force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a large risk to electronics and medical implants. These neodymiums produce a field that disrupts operation of digital equipment. Notice: the invisible magnetic field acts through matter and plastic. Exceptional care must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

NdFeB products are prone to chipping – a violent impact against metal causes immediate chipping. Control the attraction moment – a neodymium left loose speeds with massive force. Kinetic force can cause material chips or injury to fingers. Be sure to control the product during installation so it doesn't hit with great force against the metal. A collision at high speed almost guarantees destruction of the magnet. Use safety goggles when working with large magnets.

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

In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Note: On a vertical wall, the magnet holds just approx. 20-30% of its nominal pull.

2. Steel saturation

*Thin metal sheet (e.g. computer case) severely weakens the holding force.

3. Thermal stability

*For N38 material, 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) = 0.43

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.

Component MPL 40x18x10 SH / N38 features a low profile and industrial pulling force, making it a perfect solution for building separators and machines. This magnetic block with a force of 233.58 N is ready for shipment in 24h, allowing for rapid realization of your project. Additionally, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

The key to success is shifting 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. To separate the MPL 40x18x10 SH / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend care, 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. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. 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 (40x18 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: 40 mm (length), 18 mm (width), and 10 mm (thickness). It is a magnetic block with dimensions 40x18x10 mm and a self-weight of 54 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Advantages

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

They retain full power for nearly 10 years – the drop is just ~1% (according to analyses),
They are noted for resistance to demagnetization induced by presence of other magnetic fields,
By covering with a lustrous coating of silver, the element presents an nice look,
Magnetic induction on the working layer of the magnet turns out to be impressive,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
Possibility of custom forming and optimizing to atypical requirements,
Wide application in modern technologies – they find application in computer drives, motor assemblies, medical equipment, and complex engineering applications.
Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Weaknesses

Drawbacks and weaknesses of neodymium magnets and proposals for their use:

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 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 and corrosion.
Limited possibility of creating threads in the magnet and complicated forms - preferred is a housing - magnet mounting.
Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
Due to neodymium price, their price exceeds standard values,

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what contributes to it?

The specified lifting capacity concerns the limit force, measured under ideal test conditions, specifically:

with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
whose thickness equals approx. 10 mm
with an polished contact surface
with zero gap (without impurities)
for force applied at a right angle (pull-off, not shear)
at conditions approx. 20°C

Key elements affecting lifting force

Holding efficiency is affected by specific conditions, such as (from priority):

Clearance – the presence of any layer (rust, tape, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
Direction of force – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
Steel thickness – too thin steel causes magnetic saturation, causing part of the flux to be wasted into the air.
Material composition – not every steel attracts identically. Alloy additives worsen the attraction effect.
Plate texture – ground elements guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
Thermal factor – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under parallel forces the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet and the plate reduces the load capacity.

Precautions when working with NdFeB magnets

Electronic devices

Avoid bringing magnets near a wallet, computer, or TV. The magnetic field can permanently damage these devices and erase data from cards.

Serious injuries

Risk of injury: The pulling power is so immense that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.

Product not for children

These products are not intended for children. Swallowing multiple magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and necessitates immediate surgery.

Compass and GPS

A powerful magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Keep magnets near a smartphone to avoid damaging the sensors.

Magnet fragility

Neodymium magnets are sintered ceramics, which means they are fragile like glass. Collision of two magnets will cause them cracking into small pieces.

Thermal limits

Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its properties and pulling force.

Metal Allergy

A percentage of the population suffer from a contact allergy to nickel, which is the typical protective layer for neodymium magnets. Prolonged contact can result in skin redness. We suggest use protective gloves.

Immense force

Use magnets consciously. Their immense force can surprise even experienced users. Plan your moves and respect their power.

Mechanical processing

Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Pacemakers

For implant holders: Strong magnetic fields disrupt electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.
