Physical modeling of the product - technical parameters

The following values represent the direct effect of a mathematical calculation. Values are based on algorithms for the class Nd₂Fe₁₄B. Real-world parameters may differ. Use these calculations as a supplementary guide when designing systems.

Grip strength drops sharply per each millimeter of spacing. Keep in mind that even a very thin break (e.g., contamination, varnish, veneer) noticeably weakens the grip. Magnets operate optimally during direct contact; air break kills the force. See how quickly the parameters plummet, when the magnet does not adhere flatly to the steel surface. When calculating the assembly, eliminate redundant distances.

The following data calculates the approximate force needed to cause the sliding of the magnet downwards along a upright steel plate (considering typical friction). This value varies with the separation distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MP 41x15x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	7.33 kg / 16.16 LBS 7332.0 g / 71.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.89 kg / 10.78 LBS 4888.0 g / 48.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	2.44 kg / 5.39 LBS 2444.0 g / 24.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	12.22 kg / 26.94 LBS 12220.0 g / 119.9 N

When mounting a magnet on a upright wall (e.g., a car body), it will maintain barely about 20%-30% of its nominal power. Gravity and a weak degree of grip cause that magnets slip easier than they detach. Designing a wall mount? Remember that the sliding force is noticeably lower than the maximum static pull force. On a painted metal, the element will slip down under a noticeably lighter weight. Using a rubber coating can drastically improve the result.

A too thin steel is not enough to focus the entire magnetic field, which squanders power of the magnet. If you install a neodymium to a weak sheet, the field will penetrate right through and the attraction force will be weaker. To squeeze the maximum of this magnet's potential, you need a suitably thick element of metal. The material oversaturation causes that on thin elements (e.g., car bodies), the holder works worse. We recommend selecting the steel dimension according to the table below.

Ordinary NdFeB products irreversibly lose power above the temperature limit. Protect against heat – excessive heat can irreversibly demagnetize this magnet. With every degree above norm, the neodymium's power momentarily lowers. Avoid using this product near heat sources exceeding its safe range. Ignoring the limit will lead to irreversible degradation of magnetism.

*Engineering note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress compared to rod magnets. The danger warning in the table indicates permanent field degradation for this particular item.

Two magnetic products interact from a much further distance than a neodymium and metal combination. Such a system of magnet-to-magnet creates a more powerful interaction and a larger range of operation. Planning to create a powerful holder? Apply two magnets instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the pinch force is huge. The repulsion force is a bit weaker than the connection force, but still impressive.
*Field value for N-N configuration is approximately ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
* Figures apply to friction force of dual same neodymium magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Safety (HSE) (implants) - warnings

A strong magnetic field is a serious hazard to IT equipment and pacemakers. These neodymiums generate a field that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field 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, membranes, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Table 8: Collisions (kinetic energy) - warning
MP 41x15x10 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	19.95 km/h (5.54 m/s)	1.32 J
30 mm	29.88 km/h (8.30 m/s)	2.96 J
50 mm	38.13 km/h (10.59 m/s)	4.81 J
100 mm	53.84 km/h (14.96 m/s)	9.59 J

NdFeB products are very brittle – a collision with steel can result in shattering. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Striking energy can destroy the magnet or painful pinches to fingers. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when playing with powerful specimens.

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

Contrary to myths, water does not block the magnetic field. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Warning: On a vertical wall, the magnet holds merely ~20% of its nominal pull.

2. Plate thickness effect

*Thin metal sheet (e.g. 0.5mm PC case) drastically reduces the holding force.

3. Thermal stability

*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) = 0.80

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.

It is ideally suited for places where solid attachment of the magnet to the substrate is required without the risk of detachment. Thanks to the hole (often for a screw), this model enables easy screwing to wood, wall, plastic, or metal. This product with a force of 24.44 kg works great as a cabinet closure, speaker holder, or mounting element in devices.

This is a crucial issue when working with model MP 41x15x10 / N38. Neodymium magnets are sintered ceramics, which means they are very brittle and inelastic. When tightening the screw, you must maintain caution. We recommend tightening manually with a screwdriver, not an impact driver, because too much pressure will cause the ring to crack. The flat screw head should evenly press the magnet. Remember: cracking during assembly results from material properties, not a product defect.

These magnets are coated with standard Ni-Cu-Ni plating, which protects them in indoor conditions, but does not ensure full waterproofing. Damage to the protective layer during assembly is the most common cause of rusting. This product is dedicated for inside building use. For outdoor applications, we recommend choosing rubberized holders or additional protection with varnish.

The inner hole diameter determines the maximum size of the mounting element. For magnets with a straight hole, a conical head can act like a wedge and burst the magnet. Aesthetic mounting requires selecting the appropriate head size.

The presented product is a ring magnet with dimensions Ø41 mm (outer diameter) and height 10 mm. The pulling force of this model is an impressive 24.44 kg, which translates to 239.78 N in newtons. The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 15 mm.

These magnets are magnetized axially (through the thickness), which means one flat side is the N pole and the other is S. In the case of connecting two rings, make sure one is turned the right way. When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Pros as well as cons of rare earth magnets.

Benefits

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

Their strength is durable, and after approximately ten years it decreases only by ~1% (theoretically),
They maintain their magnetic properties even under strong external field,
A magnet with a metallic nickel surface looks better,
Neodymium magnets achieve maximum magnetic induction on a small area, which allows for strong attraction,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Thanks to modularity in constructing and the capacity to adapt to individual projects,
Significant place in future technologies – they are used in mass storage devices, electric motors, precision medical tools, and industrial machines.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

What to avoid - cons of neodymium magnets: tips and applications.

At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as 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 immune to moisture, when using outdoors
Due to limitations in creating threads and complicated forms in magnets, we propose using cover - magnetic mount.
Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
Due to complex production process, their price is relatively high,

Holding force characteristics

Maximum lifting capacity of the magnet – what it depends on?

The force parameter is a measurement result performed under standard conditions:

with the application of a sheet made of special test steel, guaranteeing full magnetic saturation
whose transverse dimension is min. 10 mm
with a plane cleaned and smooth
under conditions of gap-free contact (metal-to-metal)
during pulling in a direction perpendicular to the plane
at temperature approx. 20 degrees Celsius

What influences lifting capacity in practice

Real force impacted by working environment parameters, including (from priority):

Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Angle of force application – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
Steel type – mild steel attracts best. Alloy admixtures decrease magnetic permeability and lifting capacity.
Smoothness – ideal contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, however under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate lowers the holding force.

Warnings

Heat warning

Control the heat. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.

Flammability

Powder generated during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.

No play value

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

Bodily injuries

Large magnets can break fingers instantly. Never put your hand betwixt two strong magnets.

Skin irritation risks

Studies show that the nickel plating (the usual finish) is a potent allergen. If your skin reacts to metals, prevent direct skin contact and choose encased magnets.

GPS Danger

Remember: rare earth magnets produce a field that confuses sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.

Handling rules

Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.

Magnetic media

Intense magnetic fields can destroy records on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.

Medical interference

For implant holders: Powerful magnets affect electronics. Maintain at least 30 cm distance or request help to handle the magnets.

Magnet fragility

NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets leads to them shattering into small pieces.

Attention! More info about risks in the article: Safety of working with magnets.
