Pulling power weakens sharply with every subsequent millimeter of spacing. Note that even the smallest gap (e.g., contamination, paint, veneer) noticeably weakens the grip. Magnetic products operate most effectively during direct contact; gap weakens the power. See how quickly the parameters plummet, when the magnet does not adhere flatly to the steel surface. When planning the arrangement, eliminate redundant distances.

The following data calculates the theoretical shear load necessary to cause the slippage of the magnet down against a vertical steel wall (assuming typical friction). The holding force varies with the separation distance between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 17x17x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.97 kg / 2.13 pounds 966.0 g / 9.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.64 kg / 1.42 pounds 644.0 g / 6.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.32 kg / 0.71 pounds 322.0 g / 3.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.61 kg / 3.55 pounds 1610.0 g / 15.8 N

When hanging a holder on a vertical plane (e.g., a board), it will maintain barely about 1/5 of nominal attraction strength. Gravity and a low friction coefficient influence the fact that magnets slide down faster than they detach. Designing a wall mount? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the holder will slide down under a noticeably lighter weight. Utilizing a rubberized layer can drastically raise the stability.

MPL 17x17x3 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.32 kg / 0.71 pounds 322.0 g / 3.2 N
1 mm	25%	0.81 kg / 1.77 pounds 805.0 g / 7.9 N
2 mm	50%	1.61 kg / 3.55 pounds 1610.0 g / 15.8 N
3 mm	75%	2.42 kg / 5.32 pounds 2415.0 g / 23.7 N
5 mm	100%	3.22 kg / 7.10 pounds 3220.0 g / 31.6 N
10 mm	100%	3.22 kg / 7.10 pounds 3220.0 g / 31.6 N
11 mm	100%	3.22 kg / 7.10 pounds 3220.0 g / 31.6 N
12 mm	100%	3.22 kg / 7.10 pounds 3220.0 g / 31.6 N

A thin metal plate is incapable of take in the full magnetic flux, which squanders power of the holder. Should you install a neodymium to a too thin substrate, the magnetism will pass right through and the holding will be smaller. To squeeze 100% of this magnet's power, you require a sufficiently solid backing of metal. The saturation phenomenon causes that on delicate walls (e.g., car bodies), the holder works worse. We recommend selecting the steel dimension according to the table below.

Table 5: Working in heat (stability) - thermal limit
MPL 17x17x3 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status
20 °C	0.0%	3.22 kg / 7.10 pounds 3220.0 g / 31.6 N	OK
40 °C	-2.2%	3.15 kg / 6.94 pounds 3149.2 g / 30.9 N	OK
60 °C	-4.4%	3.08 kg / 6.79 pounds 3078.3 g / 30.2 N
80 °C	-6.6%	3.01 kg / 6.63 pounds 3007.5 g / 29.5 N
100 °C	-28.8%	2.29 kg / 5.05 pounds 2292.6 g / 22.5 N

Standard neodymium magnets change their properties power after exceeding the maximum temperature. Watch out for overheating – excessive heat can permanently destroy this magnet. With every degree above norm, the neodymium's power temporarily drops. Do not use this magnet near heat sources higher than its operating temperature limit. Exceeding the critical threshold will lead to permanent loss of magnetic properties.

*Engineering note: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low Pc) risk losing magnetic properties under lower heat stress than taller cylinders. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two magnetic products interact from a much further distance than a neodymium and metal combination. Such a system of two magnets generates a stronger field and a wider radius of action. Designing a strong closure? Use a pair of magnets instead of one magnet and a striker plate. Remember that when connecting a pair of magnets, the collision energy is huge. The levitation is marginally weaker than the connection force, but still large.
*Flux density between like poles drops to ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Attention: Estimates refer to sliding force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

Table 7: Protective zones (implants) - warnings
MPL 17x17x3 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	7.0 cm
Hearing aid	10 Gs (1.0 mT)	5.5 cm
Mechanical watch	20 Gs (2.0 mT)	4.5 cm
Mobile device	40 Gs (4.0 mT)	3.5 cm

Payment card	400 Gs (40.0 mT)	1.5 cm
HDD hard drive	600 Gs (60.0 mT)	1.0 cm

Powerful magnet radiation poses a large risk to electronics and pacemakers. These NdFeB products produce a flux that destroys function of digital equipment. Remember: the unseen radiation passes through tissues and glass. Exceptional care must be exercised by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, car keys, membranes, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - collision effects
MPL 17x17x3 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	23.45 km/h (6.52 m/s)	0.14 J
30 mm	38.89 km/h (10.80 m/s)	0.38 J
50 mm	50.19 km/h (13.94 m/s)	0.63 J
100 mm	70.98 km/h (19.72 m/s)	1.26 J

Magnetic elements are delicate – a strong collision with metal can result in shattering. Control the attraction moment – a neodymium left loose becomes dangerous. Impact energy can cause material chips or painful pinches to fingers. Always hold the magnet during mounting so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the magnet. 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 surface, the magnet holds just a fraction of its perpendicular strength.

2. Efficiency vs thickness

*Thin steel (e.g. computer case) severely limits the holding force.

3. Heat tolerance

*For N38 grade, 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) = 0.23

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.

Component MPL 17x17x3 / N38 features a low profile and industrial pulling force, making it an ideal solution for building separators and machines. This rectangular block with a force of 31.54 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 block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 17x17x3 / 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. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

Plate magnets MPL 17x17x3 / 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 17x17x3 / N38, we recommend utilizing two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Remember to roughen and wash 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 (17x17 mm), which is ideal for flat mounting. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

This model is characterized by dimensions 17x17x3 mm, which, at a weight of 6.5 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 17x17x3 mm and a self-weight of 6.5 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of rare earth magnets.

Benefits

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

They retain full power for around ten years – the loss is just ~1% (according to analyses),
They feature excellent resistance to weakening of magnetic properties due to opposing magnetic fields,
By using a lustrous coating of silver, the element gains an nice look,
The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to flexibility in forming and the capacity to adapt to individual projects,
Universal use in future technologies – they find application in data components, brushless drives, diagnostic systems, as well as other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in compact constructions

Disadvantages

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also increases their durability
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
Due to limitations in realizing threads and complex forms in magnets, we propose using a housing - magnetic mount.
Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that small elements of these products can disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Breakaway strength of the magnet in ideal conditions – what it depends on?

Holding force of 3.22 kg is a result of laboratory testing executed under specific, ideal conditions:

with the application of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
whose transverse dimension reaches at least 10 mm
characterized by even structure
without the slightest air gap between the magnet and steel
during detachment in a direction perpendicular to the plane
in stable room temperature

Determinants of lifting force in real conditions

In real-world applications, the actual holding force depends on several key aspects, listed from most significant:

Distance (between the magnet and the metal), because even a very small distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Steel grade – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
Surface condition – ground elements ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity was measured by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.

Precautions when working with NdFeB magnets

Heat warning

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.

No play value

These products are not suitable for play. Swallowing multiple magnets may result in them attracting across intestines, which constitutes a critical condition and requires immediate surgery.

Avoid contact if allergic

Certain individuals suffer from a hypersensitivity to nickel, which is the standard coating for NdFeB magnets. Extended handling might lead to dermatitis. It is best to use protective gloves.

Electronic devices

Very strong magnetic fields can destroy records on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.

Serious injuries

Danger of trauma: The pulling power is so great that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.

Phone sensors

GPS units and smartphones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.

Shattering risk

Watch out for shards. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.

Medical implants

Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.

Fire risk

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

Do not underestimate power

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