Technical analysis of the product - report

The following information represent the outcome of a mathematical simulation. Results were calculated on models for the material Nd₂Fe₁₄B. Operational parameters may deviate from the simulation results. Use these calculations as a preliminary roadmap when designing systems.

Table 1: Static pull force (force vs gap) - power drop
MP 30x6x10 / N38

Distance (mm)	Induction (Gauss) / mT	Pull Force (kg/lbs/g/N)	Risk Status
0 mm	5619 Gs 561.9 mT	20.71 kg / 45.66 pounds 20710.0 g / 203.2 N	critical level

50 mm	161 Gs 16.1 mT	0.02 kg / 0.04 pounds 17.0 g / 0.2 N	weak grip

Magnetic force weakens drastically with every mm of spacing. Note that even a very thin break (e.g., dirt, paint, veneer) significantly weakens the grip. Magnetic products operate most effectively at the point of direct contact; gap nullifies the force. See how quickly the parameters fall, when the product does not adhere flatly to the metal substrate. When calculating the arrangement, discard unnecessary gaps.

50 mm	Stal (~0.2)	0.00 kg / 0.01 pounds 4.0 g / 0.0 N

The following data calculates the theoretical weight limit necessary to initiate the shifting of the magnet downwards along a upright steel wall (assuming typical friction). This value varies with the gap size between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MP 30x6x10 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	6.21 kg / 13.70 pounds 6213.0 g / 60.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.14 kg / 9.13 pounds 4142.0 g / 40.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	2.07 kg / 4.57 pounds 2071.0 g / 20.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	10.36 kg / 22.83 pounds 10355.0 g / 101.6 N

When mounting a magnet on a vertical wall (e.g., a board), it will only hold barely about 20%-30% of its nominal power. Gravity as well as a low friction coefficient mean that holders move down faster than they detach. Planning a wall mount? Note that the sliding force is noticeably lower than the maximum static pull force. On a painted metal, the magnet will give way down under a significantly smaller cargo. Utilizing a rubberized coating can significantly improve the result.

12 mm	100%	20.71 kg / 45.66 pounds 20710.0 g / 203.2 N

A thin sheet is not enough to take in the full magnetic flux, which weakens actual performance of the magnet. Should you attach a powerful product to a thin surface, the field will penetrate right through and the holding will be smaller. To utilize the maximum of this magnet's potential, you require a sufficiently solid element of steel. The saturation phenomenon means that on thin elements (e.g., thin profiles), the holder works worse. We advise picking the steel thickness based on the following data.

Classic neodymiums lose parameters above the temperature limit. Watch out for overheating – high temperature can permanently destroy this product. With increasing heat, the neodymium's capacity momentarily drops. Do not use this magnet near heat sources exceeding its safe range. Too high temperature will lead to permanent loss of magnetism.

*Important note: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low Pc) risk losing magnetic properties at lower temperatures compared to rod magnets. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two strong neodymiums attract each other from a wider radius than a magnet and steel combination. Such a system of magnet-to-magnet produces a massive flux and a larger range of performance. Designing a strong closure? Apply two magnets instead of a neodymium and a steel. Be careful that when bringing together two magnets, the collision energy is extreme. The levitation is marginally weaker than the connection force, but still impressive.
*The magnetic induction for N-N configuration reaches ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
* Figures demonstrate friction force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field poses a real danger to electronics as well as pacemakers. These NdFeB products produce a flux that destroys function of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and glass. Increased vigilance must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, car keys, membranes, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a collision with steel causes immediate chipping. Control the attraction moment – a neodymium left loose becomes dangerous. Striking energy can trigger coating fragments or dangerous crushing to fingers. Be sure to control the product during mounting so it doesn't hit violently against the steel surface. A collision at high speed ends with a crack of the neodymium. Use safety goggles when handling with powerful specimens.

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

In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Note: On a vertical surface, the magnet retains merely a fraction of its perpendicular strength.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) significantly limits 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) = 0.96

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.

The ring-shaped magnet MP 30x6x10 / N38 is created for permanent mounting, where glue might fail or be insufficient. Mounting is clean and reversible, unlike gluing. It is also often used in advertising for fixing signs and in workshops for organizing tools.

This material behaves more like porcelain than steel, so it doesn't forgive mistakes during mounting. One turn too many can destroy the magnet, so do it slowly. It's a good idea to use a flexible washer under the screw head, which will cushion the stresses. Remember: cracking during assembly results from material properties, not a product defect.

Moisture can penetrate micro-cracks in the coating and cause oxidation of the magnet. Damage to the protective layer during assembly is the most common cause of rusting. If you must use it outside, paint it with anti-corrosion paint after mounting.

A screw or bolt with a thread diameter smaller than 6 mm fits this model. If the magnet does not have a chamfer (cone), we recommend using a screw with a flat or cylindrical head, or possibly using a washer. Aesthetic mounting requires selecting the appropriate head size.

This model is characterized by dimensions Ø30x10 mm and a weight of 50.89 g. The key parameter here is the holding force amounting to approximately 20.71 kg (force ~203.16 N). The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 6 mm.

These magnets are magnetized axially (through the thickness), which means one flat side is the N pole and the other is S. If you want two such magnets screwed with cones facing each other (faces) to attract, you must connect them with opposite poles (N to S). We do not offer paired sets with marked poles in this category, but they are easy to match manually.

Advantages and disadvantages of rare earth magnets.

Benefits

Besides their high retention, neodymium magnets are valued for these benefits:

They virtually do not lose power, because even after 10 years the performance loss is only ~1% (based on calculations),
Neodymium magnets are extremely resistant to loss of magnetic properties caused by magnetic disturbances,
By covering with a smooth coating of gold, the element presents an nice look,
Magnets have extremely high magnetic induction on the outer side,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
Due to the potential of free shaping and adaptation to unique needs, magnetic components can be manufactured in a broad palette of geometric configurations, which expands the range of possible applications,
Fundamental importance in modern industrial fields – they serve a role in magnetic memories, electric motors, precision medical tools, also multitasking production systems.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Cons

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
We suggest cover - magnetic holder, due to difficulties in creating threads inside the magnet and complicated shapes.
Health risk to health – tiny shards of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these products can complicate diagnosis medical in case of swallowing.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Lifting parameters

Maximum holding power of the magnet – what affects it?

The force parameter is a measurement result performed under the following configuration:

on a block made of structural steel, perfectly concentrating the magnetic field
with a cross-section of at least 10 mm
characterized by even structure
without any insulating layer between the magnet and steel
for force acting at a right angle (in the magnet axis)
in neutral thermal conditions

Practical aspects of lifting capacity – factors

Effective lifting capacity impacted by working environment parameters, mainly (from priority):

Clearance – existence of any layer (paint, tape, air) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
Angle of force application – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Material composition – different alloys attracts identically. Alloy additives weaken the attraction effect.
Plate texture – ground elements ensure maximum contact, which increases force. Rough surfaces weaken the grip.
Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate reduces the load capacity.

Precautions when working with neodymium magnets

Fragile material

Neodymium magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets leads to them shattering into shards.

Power loss in heat

Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its properties and strength.

Handling rules

Be careful. Neodymium magnets attract from a long distance and connect with massive power, often faster than you can react.

Metal Allergy

It is widely known that nickel (standard magnet coating) is a potent allergen. If you have an allergy, prevent direct skin contact and select versions in plastic housing.

Dust is flammable

Mechanical processing of neodymium magnets carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Magnetic interference

A strong magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets near a device to prevent damaging the sensors.

Swallowing risk

Neodymium magnets are not intended for children. Accidental ingestion of a few magnets may result in them attracting across intestines, which poses a severe health hazard and requires urgent medical intervention.

Crushing risk

Pinching hazard: The pulling power is so great that it can cause blood blisters, pinching, and broken bones. Use thick gloves.

Health Danger

Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.

Cards and drives

Device Safety: Strong magnets can damage data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).
