Technical analysis of the magnet - technical parameters

The following data represent the outcome of a engineering analysis. Results rely on models for the class Nd₂Fe₁₄B. Operational performance may differ from theoretical values. Please consider these data as a reference point for designers.

Magnetic force weakens drastically with every mm of gap. Remember that even the smallest gap (e.g., contamination, paint, rust) strongly weakens the grip. Magnetic products hold most effectively in perfect adhesion; gap drastically cuts the force. Notice how rapidly the parameters fall, when the product does not touch flatly to the metal substrate. When calculating the arrangement, discard unnecessary gaps.

The table below shows the approximate force necessary to cause the slippage of the magnet vertically along a upright steel wall (assuming typical friction coefficient). This parameter is a function of the separation distance between the magnet and the surface.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces

Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.77 kg / 3.91 lbs 1772.0 g / 17.4 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.89 kg / 1.95 lbs 886.0 g / 8.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	4.43 kg / 9.77 lbs 4430.0 g / 43.5 N

When hanging a holder on a upright plane (e.g., a fridge), it will maintain just approx. 20%-30% of its nominal power. Gravity as well as a weak degree of grip influence the fact that holders slide down faster than they pull off. Want to create a vertical fastening? Consider that the shear force is much weaker than the maximum static pull force. On a painted metal, the element will slide down under a significantly smaller load. Using a rubber pad can drastically improve the result.

12 mm	100%	8.86 kg / 19.53 lbs 8860.0 g / 86.9 N

A thin metal plate is incapable of focus the full magnetic flux, which squanders power of the holder. If you install a neodymium to a too thin substrate, the magnetism will penetrate right through and the attraction force will be weaker. To squeeze 100% 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 holder shows lower pull force. We advise picking the steel dimension according to the table below.

Table 5: Working in heat (stability) - power drop
MPL 30x20x5 / N38

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

Ordinary NdFeB products lose strength above the temperature limit. Avoid high temperatures – heat can irreversibly demagnetize this product. With increasing heat, the neodymium's force momentarily drops. Avoid using this magnet close to ovens exceeding its working range. Too high temperature will cause permanent loss of magnetism.

*Important note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (pancake types) risk losing magnetic properties sooner than long magnets. Warning indicator in the table signals permanent field degradation for this specific geometry.

Two strong neodymiums interact from a much further distance than a neodymium and metal combination. The connection of two magnets produces a massive flux and a further horizon of operation. Planning to create a solid fastener? Utilize two neodymiums instead of one magnet and a striker plate. Be careful that when bringing together two magnets, the pinch force is massive. The levitation is marginally weaker than the connection force, but still impressive.
*Flux density for N-N configuration is approximately ~0 Gs at the geometric center between the magnets (due to field cancellation).
Note: Estimates refer to friction force of a pair of same neodymium magnets (friction ~0.15 for Ni-Ni plating).

Table 7: Hazards (electronics) - warnings
MPL 30x20x5 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	10.5 cm
Hearing aid	10 Gs (1.0 mT)	8.5 cm
Timepiece	20 Gs (2.0 mT)	6.5 cm

A strong magnetic field is a real danger to electronics and pacemakers. These neodymiums produce a field that prevents correct functioning of digital equipment. Notice: the unseen radiation passes through tissues and housings. Special caution must be taken by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Table 8: Collisions (cracking risk) - warning
MPL 30x20x5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	21.97 km/h (6.10 m/s)	0.42 J
30 mm	34.74 km/h (9.65 m/s)	1.05 J
50 mm	44.76 km/h (12.43 m/s)	1.74 J
100 mm	63.29 km/h (17.58 m/s)	3.48 J

Magnetic elements are prone to chipping – a collision with steel risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Kinetic force can destroy the magnet or injury to skin. Hold the magnet firmly during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear eye protection when playing with large magnets.

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

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Note: On a vertical wall, the magnet retains merely approx. 20-30% of its perpendicular strength.

2. Steel saturation

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

3. Thermal stability

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.26

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 an extremely strong plate magnet made of NdFeB material, which, with dimensions of 30x20x5 mm and a weight of 22.5 g, guarantees the highest quality connection. This rectangular block with a force of 86.90 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 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 8.86 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

They constitute a key element in the production of generators and material handling systems. Thanks to the flat surface and high force (approx. 8.86 kg), they are ideal as closers in furniture making and mounting elements in automation. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 30x20x5 / N38, we recommend utilizing strong epoxy glues (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 clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 30x20x5 / N38 model is magnetized through the thickness (dimension 5 mm), which means that the N and S poles are located on its largest, flat surfaces. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

This model is characterized by dimensions 30x20x5 mm, which, at a weight of 22.5 g, makes it an element with impressive energy density. The key parameter here is the lifting capacity amounting to approximately 8.86 kg (force ~86.90 N), which, with such a flat shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Pros

In addition to their long-term stability, neodymium magnets provide the following advantages:

They have unchanged lifting capacity, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
They do not lose their magnetic properties even under external field action,
In other words, due to the shiny layer of silver, the element is aesthetically pleasing,
Magnetic induction on the working part of the magnet remains extremely intense,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of precise shaping as well as adjusting to defined applications,
Universal use in high-tech industry – they serve a role in computer drives, drive modules, precision medical tools, also technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in small systems

Weaknesses

Disadvantages of NdFeB magnets:

They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and 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 making nuts in the magnet and complicated forms - preferred is a housing - mounting mechanism.
Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that tiny parts of these magnets can be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Maximum magnetic pulling force – what affects it?

The lifting capacity listed is a measurement result performed under specific, ideal conditions:

on a plate made of structural steel, perfectly concentrating the magnetic flux
possessing a massiveness of min. 10 mm to avoid saturation
characterized by lack of roughness
with direct contact (without impurities)
under vertical force vector (90-degree angle)
at temperature room level

Determinants of practical lifting force of a magnet

Please note that the magnet holding may be lower influenced by elements below, starting with the most relevant:

Gap (between the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of nominal force).
Base massiveness – too thin steel causes magnetic saturation, causing part of the power to be wasted to the other side.
Material type – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the thermal limit for a given model.

Lifting capacity was determined using a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast 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

Keep away from children

Only for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Keep away from children and animals.

Hand protection

Big blocks can smash fingers in a fraction of a second. Do not put your hand betwixt two strong magnets.

Sensitization to coating

It is widely known that nickel (standard magnet coating) is a common allergen. If you have an allergy, refrain from direct skin contact or opt for coated magnets.

Maximum temperature

Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.

Danger to pacemakers

Patients with a heart stimulator must keep an safe separation from magnets. The magnetic field can interfere with the functioning of the life-saving device.

Flammability

Dust produced during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.

Risk of cracking

Watch out for shards. Magnets can fracture upon uncontrolled impact, launching shards into the air. We recommend safety glasses.

Electronic devices

Do not bring magnets close to a purse, laptop, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.

Respect the power

Handle magnets consciously. Their powerful strength can surprise even experienced users. Be vigilant and do not underestimate their force.

GPS and phone interference
