Grip strength weakens sharply with every mm of distance. Remember that every additional insulation layer (e.g., dirt, paint, veneer) strongly weakens the grip. Magnets hold most effectively in perfect adhesion; air break weakens the power. Observe how rapidly the load capacity plummet, when the magnet does not adhere directly to the metal substrate. When calculating the mounting, discard redundant distances.

This section calculates the estimated force required to initiate the downward movement of the magnet vertically on a upright steel wall (considering typical friction coefficient). This parameter depends on the separation distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - 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 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 placing a element on a upright plane (e.g., a fridge), it will maintain just approx. 1/5 of nominal attraction strength. Gravitational force and a weak degree of grip influence the fact that products move down easier than they detach. Want to create a vertical fastening? Consider that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the holder will slide down under a significantly smaller weight. Using a rubber coating can drastically raise the stability.

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

A too thin steel is unable to conduct the full magnetic flux, which squanders power of the magnet. If you mount a strong magnet to a too thin substrate, the field will penetrate right through and the attraction force will be weaker. To squeeze full efficiency of this neodymium's potential, you need a suitably thick piece of steel. The saturation effect means that on delicate walls (e.g., thin profiles), the magnet holds weaker. We suggest choosing the steel thickness according to the table below.

Ordinary NdFeB products irreversibly lose power above the temperature limit. Watch out for overheating – excessive heat can irreversibly damage this product. As the temperature rises, the magnet's force temporarily decreases. Do not use this product close to heaters higher than its safe range. Too high temperature will cause permanent loss of magnetism.

*Technical advisory: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Flat magnets (low permeance coefficient) may lose charge permanently sooner than long magnets. Red status in the table points to a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a significantly greater distance than a neodymium and metal setup. The setup of two magnets produces a massive flux and a larger range of operation. Planning to create a powerful holder? Utilize two neodymiums instead of one magnet and a steel. Be careful that when bringing together two magnets, the impact force is extreme. The levitation is slightly lower than the connection force, but still impressive.
*Field value between like poles drops to ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
* Estimates apply to friction force of two matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field poses a large risk to IT equipment as well as pacemakers. These magnets generate a field that destroys function of digital equipment. Remember: the unseen radiation acts through matter and housings. Special caution must be taken by people with cochlear implants and insulin pumps. The risk also applies to: 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 collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely becomes dangerous. Kinetic force 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 metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear eye protection when working with large magnets.

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

1. Shear force

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

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) significantly limits the holding force.

3. Thermal stability

*For N38 material, 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.

It is ideally suited for places where solid attachment of the magnet to the substrate is required without the risk of detachment. Mounting is clean and reversible, unlike gluing. This product with a force of 20.71 kg works great as a door latch, speaker holder, or spacer element in devices.

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. In the place of the mounting hole, the coating is thinner and can be damaged when tightening the screw, which will become a corrosion focus. This product is dedicated for indoor use. For outdoor applications, we recommend choosing rubberized holders or additional protection with varnish.

A screw or bolt with a thread diameter smaller than 6 mm fits this model. For magnets with a straight hole, a conical head can act like a wedge and burst the magnet. Always check that the screw head is not larger than the outer diameter of the magnet (30 mm), so it doesn't protrude beyond the outline.

This model is characterized by dimensions Ø30x10 mm and a weight of 50.89 g. The key parameter here is the lifting capacity amounting to approximately 20.71 kg (force ~203.16 N). The mounting hole diameter is precisely 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). When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Pros and cons of Nd₂Fe₁₄B magnets.

Benefits

Besides their exceptional strength, neodymium magnets offer the following advantages:

They do not lose strength, even after approximately 10 years – the drop in lifting capacity is only ~1% (theoretically),
Magnets effectively defend themselves against demagnetization caused by external fields,
In other words, due to the metallic surface of nickel, the element becomes visually attractive,
Magnets possess impressive magnetic induction on the outer layer,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to freedom in shaping and the ability to adapt to specific needs,
Versatile presence in modern technologies – they find application in magnetic memories, motor assemblies, medical devices, also modern systems.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Characteristics of disadvantages of neodymium magnets and ways of using them

At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
Neodymium magnets lose their force 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 stability even at temperatures up to 230°C
They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
We suggest casing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complex forms.
Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these magnets can disrupt the diagnostic process medical when they are in the body.
Due to neodymium price, their price is higher than average,

Holding force characteristics

Highest magnetic holding force – what affects it?

Breakaway force is the result of a measurement for ideal contact conditions, including:

using a plate made of high-permeability steel, serving as a magnetic yoke
whose transverse dimension is min. 10 mm
characterized by even structure
with direct contact (no coatings)
under perpendicular force direction (90-degree angle)
at standard ambient temperature

Lifting capacity in real conditions – factors

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

Clearance – the presence of any layer (rust, tape, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
Material type – the best choice is pure iron steel. Stainless steels may attract less.
Smoothness – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
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 tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.

Precautions when working with NdFeB magnets

Permanent damage

Control the heat. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.

Life threat

Individuals with a ICD must maintain an safe separation from magnets. The magnetic field can interfere with the operation of the life-saving device.

Handling rules

Exercise caution. Rare earth magnets act from a long distance and connect with massive power, often faster than you can move away.

Dust explosion hazard

Fire hazard: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.

Beware of splinters

Beware of splinters. Magnets can fracture upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.

Threat to electronics

Powerful magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.

Nickel coating and allergies

Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, refrain from direct skin contact and select versions in plastic housing.

Finger safety

Pinching hazard: The attraction force is so great that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.

Compass and GPS

An intense magnetic field negatively affects the functioning of magnetometers in phones and GPS navigation. Maintain magnets close to a device to avoid damaging the sensors.

Swallowing risk

Product intended for adults. Small elements can be swallowed, leading to serious injuries. Keep out of reach of children and animals.
