Technical modeling of the product - data

The following data represent the outcome of a physical analysis. Results were calculated on models for the material Nd₂Fe₁₄B. Actual parameters might slightly differ from theoretical values. Treat these data as a preliminary roadmap when designing systems.

Magnetic force decreases significantly with every mm of spacing. Remember that even the smallest gap (e.g., contamination, varnish, dust) strongly diminishes the holding power. Magnets hold strongest during direct contact; gap kills the force. Observe how quickly the load capacity drop, when the magnet does not touch tightly to the metal substrate. When designing the mounting, discard redundant distances.

This section defines the estimated force necessary to initiate the shifting of the magnet vertically on a upright metal surface (assuming standard friction). This value depends on the separation distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MPL 20x8x6 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.88 kg / 4.15 pounds 1881.0 g / 18.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.25 kg / 2.76 pounds 1254.0 g / 12.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.63 kg / 1.38 pounds 627.0 g / 6.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.14 kg / 6.91 pounds 3135.0 g / 30.8 N

When placing a element on a upright surface (e.g., a car body), it will maintain just about 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip mean that products slip easier than they detach. Want to create a hanger? Remember that the sliding force is significantly lower than the maximum static pull force. On a painted metal, the element will slip down under a much lighter cargo. Using a rubber pad can drastically improve the result.

A thin sheet is unable to conduct the entire magnetic field, which squanders power of the holder. If you mount a strong magnet to a too thin substrate, the field will pass right through and the attraction force will be weaker. To squeeze 100% of this neodymium's potential, you require a sufficiently solid element of steel. The saturation phenomenon means that on sheet metal structures (e.g., appliance housings), the holder works worse. We suggest choosing the steel cross-section based on the following data.

Standard neodymium magnets irreversibly lose parameters past the thermal threshold. Avoid high temperatures – heat can irreversibly damage this product. As the temperature rises, the magnet's power momentarily drops. Avoid using this product close to heaters exceeding its safe range. Exceeding the critical threshold will result in irreversible degradation of magnetic properties.

*Technical advisory: Temperature resistance is determined by both grade, but also on the magnet's shape. Thin magnets (pancake types) are more susceptible to demagnetization under lower heat stress than long magnets. Red status in the table indicates permanent field degradation for this specific geometry.

Two magnets attract each other from a significantly greater distance than a neodymium and metal setup. Such a system of two magnets creates a more powerful interaction and a further horizon of operation. Designing a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when bringing together two magnets, the impact force is extreme. The repulsion force is marginally weaker than the connection force, but still impressive.
*Flux density for N-N configuration drops to ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Note: Estimates refer to friction force of dual matching neodymium magnets (friction ~0.15 for Ni-Ni plating).

Extremely neodym field poses a real danger to electronics as well as medical implants. These neodymiums generate a flux that destroys function of digital equipment. Notice: the invisible magnetic field penetrates the body and housings. Exceptional care must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, car keys, membranes, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Magnetic elements are delicate – a violent impact against metal risks their cracking. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Impact energy can trigger coating fragments or painful pinches to fingers. Hold the magnet firmly during installation so it doesn't slam with momentum against the steel surface. A collision at high speed ends with a crack of the magnet. Wear eye protection when working with large magnets.

Rust risk: 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. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Caution: On a vertical surface, the magnet holds only ~20% of its max power.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) severely reduces the holding force.

3. Heat tolerance

*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) = 0.52

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.

Model MPL 20x8x6 / N38 features a low profile and industrial pulling force, making it an ideal solution for building separators and machines. This magnetic block with a force of 61.50 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.

The key to success is sliding the magnets along their largest connection plane (using e.g., the edge of a table), which is easier than trying to tear them apart directly. Watch your fingers! Magnets with a force of 6.27 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. They work great as fasteners 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. 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 20x8x6 / N38 model is magnetized axially (dimension 6 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 (20x8 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.

The presented product is a neodymium magnet with precisely defined parameters: 20 mm (length), 8 mm (width), and 6 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 6.27 kg (force ~61.50 N), which, with such a compact shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Pros

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

They do not lose power, even after approximately ten years – the decrease in strength is only ~1% (based on measurements),
Neodymium magnets prove to be highly resistant to loss of magnetic properties caused by external field sources,
The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to look better,
They are known for high magnetic induction at the operating surface, which affects their effectiveness,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures approaching 230°C and above...
In view of the possibility of precise forming and customization to specialized solutions, neodymium magnets can be modeled in a variety of geometric configurations, which increases their versatility,
Universal use in future technologies – they find application in computer drives, electric drive systems, diagnostic systems, as well as multitasking production systems.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Cons

Disadvantages of neodymium magnets:

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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
They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
We suggest casing - magnetic holder, due to difficulties in creating threads inside the magnet and complex forms.
Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. Additionally, tiny parts of these magnets are able to disrupt the diagnostic process medical when they are in the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Magnetic strength at its maximum – what affects it?

The declared magnet strength refers to the peak performance, measured under ideal test conditions, meaning:

using a plate made of high-permeability steel, acting as a magnetic yoke
whose thickness equals approx. 10 mm
characterized by even structure
without the slightest air gap between the magnet and steel
under axial force vector (90-degree angle)
at temperature room level

Lifting capacity in real conditions – factors

Holding efficiency impacted by specific conditions, including (from priority):

Clearance – existence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
Material composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
Plate texture – smooth surfaces ensure maximum contact, which improves force. Uneven metal reduce efficiency.
Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.

H&S for magnets

Caution required

Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.

Do not overheat magnets

Do not overheat. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).

Shattering risk

NdFeB magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets will cause them breaking into small pieces.

This is not a toy

Absolutely store magnets out of reach of children. Ingestion danger is high, and the effects of magnets clamping inside the body are fatal.

Precision electronics

A powerful magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Maintain magnets close to a device to avoid damaging the sensors.

Hand protection

Large magnets can smash fingers instantly. Do not put your hand between two strong magnets.

Life threat

Warning for patients: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or request help to handle the magnets.

Do not drill into magnets

Mechanical processing of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Threat to electronics

Intense magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Keep a distance of min. 10 cm.

Nickel coating and allergies

A percentage of the population suffer from a sensitization to nickel, which is the common plating for NdFeB magnets. Frequent touching can result in dermatitis. We strongly advise use safety gloves.

Important! More info about hazards in the article: Safety of working with magnets.
