Engineering analysis of the assembly - technical parameters

The following information represent the direct effect of a physical analysis. Results are based on algorithms for the class Nd₂Fe₁₄B. Operational performance may differ from theoretical values. Please consider these calculations as a reference point during assembly planning.

Pulling power weakens sharply with every subsequent millimeter of distance. Keep in mind that even a microscopic distance (e.g., contamination, varnish, rust) strongly reduces the pull force. Neodymiums work optimally during direct contact; gap nullifies the power. See how flashily the load capacity drop, when the product does not touch tightly to the steel surface. When calculating the assembly, discard additional spacers.

The table below presents the estimated weight limit sufficient to start the slippage of the magnet downwards on a vertical steel plate (assuming standard friction coefficient). This value varies with the gap size between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 30x20x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	5.86 kg / 12.92 lbs 5859.0 g / 57.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	3.91 kg / 8.61 lbs 3906.0 g / 38.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	1.95 kg / 4.31 lbs 1953.0 g / 19.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	9.77 kg / 21.53 lbs 9765.0 g / 95.8 N

When hanging a magnet on a vertical surface (e.g., a car body), it will only hold barely about 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip influence the fact that magnets move down easier than they pop off the substrate. Designing a hanger? Consider that the sliding force is much weaker than the maximum static pull force. On a smooth steel, the holder will slip down under a much lighter load. Using a rubber pad can drastically increase the grip.

Table 4: Steel thickness (saturation) - sheet metal selection
MPL 30x20x10 / N38

12 mm	100%	19.53 kg / 43.06 lbs 19530.0 g / 191.6 N

A thin metal plate is unable to absorb the full magnetic flux, which wastes potential of the holder. Should you mount a strong magnet to a thin surface, the magnetism will penetrate right through and the attraction force will be weaker. To utilize the maximum of this neodymium's power, you need a suitably thick element of metal. The saturation phenomenon means that on delicate walls (e.g., appliance housings), the magnet shows lower pull force. We suggest choosing the steel cross-section according to the table below.

Table 5: Working in heat (stability) - resistance threshold
MPL 30x20x10 / N38

Ambient temp. (°C)	Power loss	Remaining pull (kg/lbs/g/N)	Status

Classic neodymiums change their properties parameters after exceeding the maximum temperature. Watch out for overheating – high temperature can permanently destroy this magnet. With increasing heat, the magnet's capacity momentarily drops. Do not use this magnet close to heaters higher than its working range. Exceeding the critical threshold will result in destruction of magnetism.

*Engineering note: Thermal stability depends not only on the material grade, as well as the dimension ratios. Thin magnets (pancake types) are more susceptible to demagnetization sooner than taller cylinders. Red status in the table signals a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a wider radius than a magnet and sheet setup. The setup of two magnets produces a massive flux and a wider radius of action. Planning to create a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Remember that when bringing together two magnets, the pinch force is massive. The repulsion force is a bit weaker than the attraction, but still large.
*The magnetic induction between like poles drops to ~0 Gs at the geometric center between the magnets (due to field cancellation).
Attention: Calculations apply to friction force of a pair of matching magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a large risk to electronics and pacemakers. These magnets produce a flux that prevents correct functioning of digital equipment. Be aware: the unseen radiation penetrates the body and housings. Increased vigilance must be taken by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, car keys, speakers, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Neodymium magnets are delicate – a strong collision with metal causes immediate chipping. Watch the impact speed – a neodymium left loose turns into a projectile. Kinetic force can cause material chips or painful pinches to skin. Be sure to control the product during installation so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Use safety goggles when handling with large magnets.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

In water, the magnet feels stronger thanks to Archimedes' principle. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

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

2. Efficiency vs thickness

*Thin steel (e.g. computer case) significantly reduces the holding force.

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.46

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.

7.38 ZŁ brutto / pcs

Model MPL 30x20x10 / N38 features a low profile and industrial pulling force, making it an ideal solution for building separators and machines. As a block magnet with high power (approx. 19.53 kg), this product is available off-the-shelf from our warehouse in Poland. 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. Watch your fingers! Magnets with a force of 19.53 kg can pinch very hard and cause hematomas. 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 generators and material handling systems. Thanks to the flat surface and high force (approx. 19.53 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.

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 10 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 19.53 kg (force ~191.55 N), which, with such a compact shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Pros and cons of Nd₂Fe₁₄B magnets.

Pros

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

They do not lose magnetism, even during around ten years – the drop in power is only ~1% (based on measurements),
They are resistant to demagnetization induced by external magnetic fields,
In other words, due to the reflective surface of nickel, the element becomes visually attractive,
Magnets are characterized by extremely high magnetic induction on the surface,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Possibility of exact creating as well as adjusting to individual requirements,
Wide application in future technologies – they are used in magnetic memories, drive modules, medical equipment, and technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in compact constructions

Limitations

Problematic aspects of neodymium magnets: application proposals

To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
Limited possibility of producing threads in the magnet and complex forms - preferred is a housing - mounting mechanism.
Health risk to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that tiny parts of these magnets are able to be problematic in diagnostics medical after entering the body.
With large orders the cost of neodymium magnets can be a barrier,

Holding force characteristics

Maximum lifting force for a neodymium magnet – what affects it?

The specified lifting capacity represents the maximum value, recorded under ideal test conditions, meaning:

with the contact of a sheet made of low-carbon steel, ensuring maximum field concentration
with a thickness no less than 10 mm
characterized by even structure
without the slightest clearance between the magnet and steel
for force applied at a right angle (pull-off, not shear)
in stable room temperature

Practical aspects of lifting capacity – factors

It is worth knowing that the magnet holding will differ subject to elements below, starting with the most relevant:

Distance (betwixt the magnet and the metal), since even a very small distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, rust or dirt).
Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be wasted to the other side.
Chemical composition of the base – mild steel gives the best results. Higher carbon content lower magnetic properties and lifting capacity.
Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, whereas under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet’s surface and the plate reduces the holding force.

Safety rules for work with NdFeB magnets

Combustion hazard

Powder produced during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Bodily injuries

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

Warning for allergy sufferers

Certain individuals experience a sensitization to Ni, which is the standard coating for NdFeB magnets. Frequent touching may cause an allergic reaction. It is best to wear safety gloves.

Choking Hazard

Product intended for adults. Small elements pose a choking risk, causing intestinal necrosis. Store out of reach of children and animals.

Medical implants

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

Demagnetization risk

Avoid heat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).

Eye protection

NdFeB magnets are sintered ceramics, which means they are very brittle. Collision of two magnets leads to them breaking into shards.

Keep away from electronics

An intense magnetic field disrupts the functioning of magnetometers in phones and GPS navigation. Maintain magnets near a smartphone to avoid breaking the sensors.

Conscious usage

Use magnets with awareness. Their huge power can shock even professionals. Stay alert and do not underestimate their force.

Electronic devices
