Magnetic force drops significantly with every mm of gap. Note that even the smallest gap (e.g., contamination, varnish, dust) strongly diminishes the holding power. Magnets hold optimally at the point of direct contact; distance weakens the power. Notice how flashily the pull force fall, when the product does not touch flatly to the metal substrate. When calculating the arrangement, avoid unnecessary gaps.

The table below shows the estimated holding capacity necessary to initiate the shifting of the magnet down against a upright steel wall (assuming standard friction coefficient). This value is a function of the distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 40x15x6 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	4.26 kg / 9.40 pounds 4263.0 g / 41.8 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	2.84 kg / 6.27 pounds 2842.0 g / 27.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.42 kg / 3.13 pounds 1421.0 g / 13.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	7.11 kg / 15.66 pounds 7105.0 g / 69.7 N

When hanging a holder on a upright plane (e.g., a car body), it you can count on barely approx. 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip mean that magnets slip easier than they pull off. Planning a vertical fastening? Remember that the shear force is noticeably lower than the maximum static pull force. On a slippery surface, the element will slide down under a much lighter cargo. Application of an anti-slip coating can effectively improve the result.

3 mm	38%	5.33 kg / 11.75 pounds 5328.8 g / 52.3 N
5 mm	63%	8.88 kg / 19.58 pounds 8881.3 g / 87.1 N

12 mm	100%	14.21 kg / 31.33 pounds 14210.0 g / 139.4 N

A thin sheet is incapable of focus the entire magnetic field, which squanders power of the holder. If you install a neodymium to a thin surface, the magnetism will pass right through and the attraction force will be weaker. To achieve 100% of this neodymium's potential, you need a suitably thick backing of steel. The saturation phenomenon causes that on thin elements (e.g., car bodies), the magnet holds weaker. We recommend selecting the steel cross-section based on the following data.

Standard neodymium magnets change their properties strength after exceeding the maximum temperature. Avoid high temperatures – high temperature can permanently demagnetize this magnet. As the temperature rises, the neodymium's force momentarily lowers. Avoid using this magnet close to ovens higher than its safe range. Ignoring the limit will cause irreversible degradation of magnetism.

*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Flat magnets (pancake types) risk losing magnetic properties at lower temperatures than long magnets. Red status in the table signals permanent field degradation for this specific geometry.

Two strong neodymiums attract each other from a significantly greater distance than a magnet and sheet combination. Such a system of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Designing a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Exercise caution that when attracting two neodymiums, the pinch force is huge. The repulsion force is slightly lower than the attraction, but still large.
*Field value between like poles is approximately ~0 Gs at the midpoint between the magnets (due to field cancellation).
* Estimates apply to friction force of dual identical magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field is a large risk to electronic devices and medical implants. These neodymiums produce a flux that disrupts operation of sensitive medical devices. Remember: the unseen radiation penetrates the body and plastic. Special caution must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, remotes, membranes, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Magnetic elements are very brittle – a collision with steel risks their cracking. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Kinetic force can trigger coating fragments or injury to skin. Hold the magnet firmly during mounting so it doesn't slam with momentum against the steel surface. A collision at high speed means shattering of the neodymium. Use safety goggles when handling 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

*Note: On a vertical wall, the magnet holds only a fraction of its nominal pull.

2. Steel saturation

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

3. Power loss vs temp

*For standard magnets, 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) = 0.31

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 40x15x6 mm and a weight of 27 g, guarantees premium class connection. This magnetic block with a force of 139.45 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.

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 40x15x6 / 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. 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 wind generators and material handling systems. They work great as invisible mounts 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. 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. 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), 15 mm (width), and 6 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 14.21 kg (force ~139.45 N), which, with such a compact shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of Nd₂Fe₁₄B magnets.

Pros

Besides their durability, neodymium magnets are valued for these benefits:

They have unchanged lifting capacity, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
Neodymium magnets prove to be highly resistant to demagnetization caused by external magnetic fields,
By using a reflective layer of nickel, the element presents an nice look,
Magnetic induction on the working part of the magnet turns out to be strong,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
Considering the option of precise shaping and customization to custom solutions, NdFeB magnets can be produced in a variety of shapes and sizes, which amplifies use scope,
Versatile presence in advanced technology sectors – they are utilized in data components, electric drive systems, medical devices, as well as modern systems.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Cons

Disadvantages of NdFeB magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
When exposed to high temperature, neodymium magnets suffer 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 rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
We recommend casing - magnetic mount, due to difficulties in creating nuts inside the magnet and complex forms.
Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Furthermore, small components of these magnets are able to disrupt the diagnostic process medical after entering the body.
Due to expensive raw materials, their price is higher than average,

Lifting parameters

Maximum holding power of the magnet – what it depends on?

The declared magnet strength refers to the maximum value, obtained under laboratory conditions, namely:

with the use of a yoke made of special test steel, ensuring maximum field concentration
possessing a massiveness of at least 10 mm to ensure full flux closure
with a surface perfectly flat
without the slightest insulating layer between the magnet and steel
during pulling in a direction vertical to the mounting surface
at standard ambient temperature

Magnet lifting force in use – key factors

Effective lifting capacity impacted by specific conditions, mainly (from most important):

Distance (between the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to paint, rust or dirt).
Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Steel thickness – insufficiently thick sheet does not close the flux, causing part of the power to be escaped into the air.
Metal type – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, whereas under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet and the plate lowers the holding force.

Precautions when working with NdFeB magnets

Heat warning

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

Machining danger

Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.

Electronic hazard

Powerful magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.

Danger to pacemakers

Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.

Bodily injuries

Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, destroying anything in their path. Be careful!

No play value

Adult use only. Tiny parts can be swallowed, leading to serious injuries. Store away from kids and pets.

Immense force

Exercise caution. Rare earth magnets attract from a long distance and connect with massive power, often faster than you can move away.

Keep away from electronics

Note: rare earth magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your mobile, device, and GPS.

Fragile material

Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.

Skin irritation risks

Studies show that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, prevent touching magnets with bare hands or opt for coated magnets.
