Engineering analysis of the assembly - technical parameters

Presented data represent the result of a physical analysis. Results were calculated on algorithms for the class Nd₂Fe₁₄B. Operational performance might slightly differ from theoretical values. Use these data as a preliminary roadmap for designers.

Grip strength drops significantly with every subsequent millimeter of spacing. Keep in mind that every additional insulation layer (e.g., contamination, paint, rust) strongly reduces the pull force. Neodymiums work optimally at the point of direct contact; air break kills the power. Observe how rapidly the load capacity plummet, when the magnet does not adhere directly to the steel surface. When calculating the arrangement, eliminate additional spacers.

This section shows the theoretical force needed to cause the slippage of the magnet down against a vertical steel plate (considering standard friction coefficient). This value is a function of the separation distance between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull

Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.17 kg / 2.59 lbs 1174.0 g / 11.5 N

Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	2.94 kg / 6.47 lbs 2935.0 g / 28.8 N

When mounting a magnet on a vertical wall (e.g., a board), it will maintain only about 20%-30% of its nominal power. Gravity and a weak degree of grip influence the fact that products slide down easier than they detach. Want to create a vertical fastening? Consider that the shear force is significantly lower than the perpendicular breakaway force. On a painted metal, the magnet will give way down under a significantly smaller load. Utilizing a rubberized coating can significantly increase the grip.

A thin sheet is unable to take in the entire magnetic field, which wastes potential of the holder. If you mount a strong magnet to a weak sheet, the field will penetrate right through and the attraction force will be weaker. To achieve the maximum of this neodymium's power, you require a sufficiently solid backing of metal. The saturation effect means that on delicate walls (e.g., car bodies), the holder shows lower pull force. We advise picking the steel cross-section based on the following data.

Standard neodymium magnets lose power above the temperature limit. Watch out for overheating – excessive heat can permanently demagnetize this magnet. With every degree above norm, the neodymium's capacity momentarily decreases. Refrain from using this product close to ovens higher than its safe range. Exceeding the critical threshold will cause irreversible degradation of magnetic properties.

*Engineering note: Heat tolerance is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) risk losing magnetic properties at lower temperatures compared to rod magnets. Warning indicator in the table indicates a risk of irreversible loss for this particular item.

Two magnets interact from a wider radius than a magnet and sheet setup. The setup of magnet-to-magnet produces a massive flux and a further horizon of operation. Designing a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Exercise caution that when attracting two neodymiums, the collision energy is huge. The repulsion force is a bit weaker than the connection force, but still significant.
*The magnetic induction between like poles is approximately ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Note: Calculations apply to shear force of two matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a serious hazard to IT equipment and pacemakers. These magnets generate a flux that destroys function of sensitive medical devices. Remember: the invisible magnetic field passes through tissues and glass. Increased vigilance must be taken by people with cochlear implants and drug dispensers. Influence will be felt by: mechanical watches, remotes, membranes, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Neodymium magnets are very brittle – a violent impact against metal causes immediate chipping. Watch the impact speed – a neodymium left loose speeds with massive force. Impact energy can destroy the magnet or injury to fingers. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the metal. A collision at high speed almost guarantees destruction of the neodymium. Wear safety glasses when working with large magnets.

Environment	Effective steel pull	Effect
Air (land)	5.87 kg	Standard
Water (riverbed)	6.72 kg (+0.85 kg buoyancy gain)	+14.5%

Rust risk: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

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

2. Plate thickness effect

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

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.40

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 15x15x5 / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 5.87 kg), this product is available immediately 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 5.87 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 15x15x5 / 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. In practice, this means that this magnet has the greatest attraction force on its main planes (15x15 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 15x15x5 mm, which, at a weight of 8.44 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 15x15x5 mm and a self-weight of 8.44 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Strengths

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

They do not lose strength, even after approximately 10 years – the drop in power is only ~1% (theoretically),
Magnets very well protect themselves against loss of magnetization caused by foreign field sources,
The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to present itself better,
Neodymium magnets create maximum magnetic induction on a contact point, which allows for strong attraction,
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 accurate forming as well as optimizing to concrete conditions,
Significant place in modern technologies – they serve a role in mass storage devices, electric drive systems, medical equipment, also multitasking production systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Characteristics of disadvantages of neodymium magnets and ways of using them

They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. 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 strength 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
Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
Limited possibility of making nuts in the magnet and complicated forms - recommended is casing - magnetic holder.
Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Highest magnetic holding force – what affects it?

Magnet power is the result of a measurement for ideal contact conditions, including:

on a base made of structural steel, perfectly concentrating the magnetic flux
with a cross-section minimum 10 mm
characterized by even structure
under conditions of ideal adhesion (metal-to-metal)
during detachment in a direction perpendicular to the mounting surface
at temperature approx. 20 degrees Celsius

Practical lifting capacity: influencing factors

Holding efficiency is affected by specific conditions, mainly (from priority):

Clearance – existence of any layer (rust, tape, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
Plate material – low-carbon steel gives the best results. Alloy admixtures reduce magnetic properties and holding force.
Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was measured with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate lowers the lifting capacity.

H&S for magnets

Pinching danger

Mind your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!

Sensitization to coating

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness occurs, cease working with magnets and wear gloves.

Heat warning

Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. This process is irreversible.

Impact on smartphones

Note: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.

Handling guide

Use magnets with awareness. Their powerful strength can shock even experienced users. Be vigilant and respect their power.

Threat to electronics

Avoid bringing magnets near a wallet, laptop, or TV. The magnetic field can permanently damage these devices and wipe information from cards.

Choking Hazard

Absolutely keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are tragic.

ICD Warning

Individuals with a heart stimulator have to maintain an large gap from magnets. The magnetism can stop the operation of the implant.

Risk of cracking

Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.

Mechanical processing

Dust produced during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
