Pulling power weakens drastically per each millimeter of distance. Remember that even the smallest gap (e.g., dirt, varnish, veneer) strongly reduces the pull force. Magnets operate optimally at the point of direct contact; distance weakens the force. See how rapidly the parameters fall, when the product does not touch tightly to the steel surface. When designing the arrangement, eliminate unnecessary gaps.

This section presents the approximate weight limit necessary to initiate the slippage of the magnet down against a vertical steel wall (considering standard friction coefficient). This value is relative to the gap size between the magnet and the surface.

When placing a holder on a upright surface (e.g., a board), it you can count on just approx. 1/5 of its nominal power. Gravitational force and a weak degree of grip cause that magnets slip easier than they pop off the substrate. Designing a wall mount? Note that the sliding force is significantly lower than the maximum static pull force. On a painted metal, the holder will give way down under a noticeably lighter weight. Utilizing a rubberized coating can effectively increase the grip.

A thin metal plate is not enough to take in the entire magnetic field, which wastes potential of the holder. If you mount a strong magnet to a weak sheet, the magnetism will penetrate right through and the holding will be smaller. To achieve 100% of this neodymium's power, you need a suitably thick element of metal. The material oversaturation causes that on delicate walls (e.g., appliance housings), the magnet shows lower pull force. We advise picking the steel cross-section according to the table below.

Classic neodymiums change their properties power after exceeding the maximum temperature. Avoid high temperatures – heat can permanently damage this product. With every degree above norm, the neodymium's capacity temporarily lowers. Refrain from using this magnet close to heaters exceeding its safe range. Exceeding the critical threshold will lead to destruction of magnetic properties.
*Technical advisory: Temperature resistance is determined by both grade, but also on the magnet's shape. Low-profile magnets (pancake types) are more susceptible to demagnetization sooner compared to rod magnets. The danger warning in the table indicates permanent field degradation for this particular item.

Two magnets attract each other from a much further distance than a magnet and steel combination. The setup of two magnets creates a more powerful interaction and a larger range of performance. Planning to create a strong closure? Utilize two neodymiums instead of a neodymium and a striker plate. Exercise caution that when attracting two neodymiums, the pinch force is huge. The repulsion force is slightly lower than the connection force, but still impressive.
*The magnetic induction for N-N configuration drops to ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Important: Estimates apply to shear force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation poses a large risk to electronic devices and pacemakers. These magnets produce a flux that prevents correct functioning of sensitive medical devices. Notice: the unseen radiation acts through matter and glass. Special caution must be taken by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, car keys, membranes, and displays. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Neodymium magnets are very brittle – a strong collision with metal risks their cracking. Watch the impact speed – a magnet released freely speeds with massive force. Kinetic force can trigger coating fragments or dangerous crushing to fingers. Always hold the magnet during mounting so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the neodymium. Wear eye protection when handling with large magnets.

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.
1. Wall mount (shear)

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

2. Efficiency vs thickness

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.13

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 Pc (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 Pc 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.

Model MPL 11x11x1 / N38 features a flat shape and professional pulling force, making it a perfect solution for building separators and machines. This rectangular block with a force of 4.24 N is ready for shipment in 24h, allowing for rapid realization of your project. Furthermore, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.
Separating strong flat 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 0.43 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.
Plate magnets MPL 11x11x1 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. They work great as invisible mounts under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.
For mounting flat magnets MPL 11x11x1 / N38, we recommend utilizing 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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).
Standardly, the MPL 11x11x1 / N38 model is magnetized axially (dimension 1 mm), which means that the N and S poles are located on its largest, flat surfaces. In practice, this means that this magnet has the greatest attraction force on its main planes (11x11 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: 11 mm (length), 11 mm (width), and 1 mm (thickness). It is a magnetic block with dimensions 11x11x1 mm and a self-weight of 0.91 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of rare earth magnets.

Benefits

In addition to their magnetic capacity, neodymium magnets provide the following advantages:
  • They have constant strength, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
  • They feature excellent resistance to weakening of magnetic properties due to external magnetic sources,
  • A magnet with a shiny gold surface is more attractive,
  • They are known for high magnetic induction at the operating surface, which affects their effectiveness,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • Thanks to flexibility in shaping and the capacity to customize to unusual requirements,
  • Wide application in future technologies – they serve a role in mass storage devices, electromotive mechanisms, advanced medical instruments, and multitasking production systems.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in miniature devices

Disadvantages

Cons of neodymium magnets and ways of using them
  • At very strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • When exposed to high temperature, neodymium magnets experience a drop in strength. 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
  • They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Limited possibility of producing nuts in the magnet and complicated forms - preferred is casing - mounting mechanism.
  • Health risk resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child safety. Additionally, small elements of these products can complicate diagnosis medical when they are in the body.
  • High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Maximum magnetic pulling force – what it depends on?

The force parameter is a theoretical maximum value performed under the following configuration:
  • on a plate made of structural steel, perfectly concentrating the magnetic field
  • with a thickness no less than 10 mm
  • with a surface perfectly flat
  • without any insulating layer between the magnet and steel
  • during pulling in a direction perpendicular to the plane
  • in temp. approx. 20°C

Practical lifting capacity: influencing factors

Holding efficiency is influenced by working environment parameters, including (from priority):
  • Distance – existence of foreign body (paint, dirt, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
  • Load vector – maximum parameter is obtained only during perpendicular pulling. The force required to slide of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
  • Base massiveness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be wasted into the air.
  • Material composition – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
  • Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
  • Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).

Lifting capacity was assessed by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.

H&S for magnets
Medical interference

Patients with a heart stimulator must keep an large gap from magnets. The magnetism can interfere with the functioning of the implant.

Sensitization to coating

Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness occurs, cease handling magnets and use protective gear.

Cards and drives

Avoid bringing magnets close to a purse, laptop, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.

Compass and GPS

Navigation devices and smartphones are highly susceptible to magnetism. Close proximity with a strong magnet can permanently damage the internal compass in your phone.

Magnet fragility

Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Respect the power

Use magnets consciously. Their huge power can shock even experienced users. Plan your moves and do not underestimate their power.

Heat sensitivity

Avoid heat. Neodymium magnets are susceptible to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Choking Hazard

Neodymium magnets are not toys. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and necessitates urgent medical intervention.

Crushing force

Protect your hands. Two large magnets will join instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!

Combustion hazard

Dust created during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.
