Magnetic force weakens significantly with every mm of spacing. Remember that even a very thin break (e.g., dirt, varnish, veneer) strongly reduces the pull force. Neodymiums operate strongest during direct contact; distance weakens the power. Analyze how flashily the load capacity plummet, when the magnet does not touch tightly to the steel surface. When planning the assembly, eliminate additional spacers.

This section defines the theoretical shear load sufficient to initiate the downward movement of the magnet down against a upright steel wall (considering typical friction coefficient). The holding force depends on the separation distance between the magnet and the surface.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces
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 LBS 6213.0 g / 60.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.14 kg / 9.13 LBS 4142.0 g / 40.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	2.07 kg / 4.57 LBS 2071.0 g / 20.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	10.36 kg / 22.83 LBS 10355.0 g / 101.6 N

When hanging a magnet on a upright plane (e.g., a board), it will maintain just about 1/5 of nominal attraction strength. Gravity as well as a low friction coefficient mean that products move down faster than they detach. Designing a wall mount? Note that the shear force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the holder will slide down under a much lighter load. Utilizing a rubberized pad can effectively increase the grip.

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)

3 mm	38%	7.77 kg / 17.12 LBS 7766.3 g / 76.2 N
5 mm	63%	12.94 kg / 28.54 LBS 12943.8 g / 127.0 N
10 mm	100%	20.71 kg / 45.66 LBS 20710.0 g / 203.2 N

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

A thin sheet cannot focus the entire magnetic field, which wastes potential of the holder. Should you mount a strong magnet to a thin surface, the flux 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 element of steel. The saturation phenomenon means that on sheet metal structures (e.g., car bodies), the magnet works worse. We recommend selecting the steel dimension according to the table below.

Classic neodymiums change their properties strength after exceeding the maximum temperature. Watch out for overheating – heat can irreversibly destroy this product. With every degree above norm, the neodymium's force briefly decreases. Refrain from using this product close to heaters exceeding its working range. Exceeding the critical threshold will cause destruction of magnetic properties.

*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) are more susceptible to demagnetization under lower heat stress than long magnets. The danger warning in the table points to a risk of irreversible loss for this particular item.

Two magnets interact from a much further distance than a magnet and steel combination. The setup of two magnets generates a stronger field and a larger range of action. Designing a solid fastener? Utilize two neodymiums instead of one magnet and a steel. Exercise caution that when attracting two neodymiums, the impact force is huge. The repulsion force is a bit weaker than the connection force, but still large.
*Flux density in repulsion mode reaches ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
Attention: Results demonstrate sliding force of two same magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field poses a real danger to electronic devices as well as medical implants. These magnets generate a field that destroys function of sensitive medical devices. Notice: the unseen radiation penetrates the body and plastic. 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 bring the product near payment cards, HDD media, or precise measuring instruments.

Neodymium magnets are very brittle – a violent impact against metal can result in shattering. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Striking energy can destroy the magnet or painful pinches to fingers. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when playing with powerful specimens.

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

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Shear force

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

2. Steel saturation

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

3. Temperature resistance

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.96

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.

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. It is also often used in advertising for fixing signs and in workshops for organizing tools.

This is a crucial issue when working with model MP 30x6x10 / 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.

Moisture can penetrate micro-cracks in the coating and cause oxidation of the magnet. In the place of the mounting hole, the coating is thinner and easily scratched when tightening the screw, which will become a corrosion focus. If you must use it outside, paint it with anti-corrosion paint after mounting.

The inner hole diameter determines the maximum size of the mounting element. 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 pulling force of this model is an impressive 20.71 kg, which translates to 203.16 N in newtons. The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 6 mm.

The poles are located on the planes with holes, not on the sides of the ring. 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). When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Advantages as well as disadvantages of rare earth magnets.

Pros

Besides their exceptional magnetic power, neodymium magnets offer the following advantages:

They retain full power for almost 10 years – the drop is just ~1% (according to analyses),
Neodymium magnets remain extremely resistant to demagnetization caused by external magnetic fields,
A magnet with a shiny gold surface has better aesthetics,
The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of exact modeling and adjusting to defined requirements,
Fundamental importance in electronics industry – they are utilized in data components, electric motors, precision medical tools, also complex engineering applications.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Weaknesses

What to avoid - cons of neodymium magnets and proposals for their use:

At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
We suggest a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complex forms.
Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets can be problematic in diagnostics medical when they are in the body.
Due to neodymium price, their price is relatively high,

Holding force characteristics

Magnetic strength at its maximum – what contributes to it?

The declared magnet strength refers to the peak performance, obtained under optimal environment, specifically:

with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
with a thickness no less than 10 mm
with a plane perfectly flat
under conditions of no distance (surface-to-surface)
for force applied at a right angle (in the magnet axis)
in temp. approx. 20°C

Practical aspects of lifting capacity – factors

Please note that the magnet holding will differ influenced by elements below, starting with the most relevant:

Air gap (between the magnet and the metal), as even a very small distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
Direction of force – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
Base massiveness – too thin steel does not accept the full field, causing part of the flux to be lost to the other side.
Metal type – not every steel attracts identically. High carbon content weaken the attraction effect.
Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces reduce efficiency.
Temperature – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was measured using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate reduces the holding force.

Precautions when working with NdFeB magnets

No play value

Product intended for adults. Tiny parts pose a choking risk, leading to severe trauma. Store away from kids and pets.

Pacemakers

Health Alert: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.

Heat warning

Keep cool. Neodymium magnets are sensitive to temperature. If you require operation above 80°C, look for HT versions (H, SH, UH).

Serious injuries

Protect your hands. Two large magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Compass and GPS

Note: rare earth magnets generate a field that disrupts sensitive sensors. Keep a separation from your phone, tablet, and navigation systems.

Allergic reactions

Studies show that the nickel plating (the usual finish) is a potent allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or select versions in plastic housing.

Fire risk

Powder created during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.

Magnets are brittle

Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.

Data carriers
