Pulling power weakens significantly with every mm of spacing. Note that every additional insulation layer (e.g., contamination, varnish, veneer) significantly diminishes the holding power. Magnets operate strongest at the point of direct contact; distance weakens the power. Notice how rapidly the pull force plummet, when the product does not touch directly to the steel surface. When calculating the assembly, eliminate redundant distances.

This section shows the estimated weight limit sufficient to cause the downward movement of the magnet downwards along a upright metal surface (considering typical friction coefficient). The holding force depends on the air gap between the magnet and the metal.

Table 3: Wall mounting (shearing) - behavior on slippery surfaces

Raw steel	µ = 0.3 30% Nominalnej Siły	0.22 kg / 0.50 LBS 225.0 g / 2.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.33 LBS 150.0 g / 1.5 N

When placing a element on a vertical plane (e.g., a car body), it will only hold only approx. 1/5 of nominal attraction strength. Gravitational force as well as a weak degree of grip influence the fact that magnets slide down easier than they pop off the substrate. Want to create a vertical fastening? Remember that the shear force is much weaker than the maximum static pull force. On a smooth steel, the magnet will slip down under a significantly smaller weight. Application of an anti-slip pad can drastically improve the result.

12 mm	100%	0.75 kg / 1.65 LBS 750.0 g / 7.4 N

A too thin steel is incapable of absorb the full magnetic flux, which wastes potential of the magnet. If you install a neodymium to a thin surface, the flux will penetrate right through and the pull force will drop sharply. To squeeze 100% of this neodymium's potential, you need a suitably thick piece of metal. The saturation effect causes that on sheet metal structures (e.g., thin profiles), the holder works worse. We suggest choosing the steel cross-section according to the table below.

Ordinary NdFeB products change their properties parameters after exceeding the maximum temperature. Watch out for overheating – excessive heat can permanently demagnetize this product. With increasing heat, the magnet's capacity temporarily lowers. Avoid using this magnet close to heaters higher than its operating temperature limit. Too high temperature will lead to permanent loss of magnetism.

*Technical advisory: Thermal stability depends not only on the material grade, as well as the dimension ratios. Thin magnets (low Pc) risk losing magnetic properties under lower heat stress compared to rod magnets. The danger warning in the table signals a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a wider radius than a magnet and steel combination. Such a system of two magnets creates a more powerful interaction and a further horizon of action. Planning to create a solid fastener? Apply two magnets instead of one magnet and a striker plate. Remember that when connecting a pair of magnets, the collision energy is huge. The levitation is a bit weaker than the connection force, but still significant.
*The magnetic induction in repulsion mode reaches ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
* Calculations show sliding force of two same neodymium magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field poses a serious hazard to IT equipment as well as pacemakers. These NdFeB products produce a field that disrupts operation of sensitive medical devices. Be aware: the unseen radiation penetrates the body and housings. Special caution must be taken by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, car keys, speakers, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Collisions (kinetic energy) - warning
MP 5x2.7/1.2x5 C / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	33.26 km/h (9.24 m/s)	0.03 J
30 mm	57.59 km/h (16.00 m/s)	0.09 J
50 mm	74.35 km/h (20.65 m/s)	0.15 J
100 mm	105.14 km/h (29.21 m/s)	0.29 J

NdFeB products are prone to chipping – a strong collision with metal can result in shattering. Watch the impact speed – a magnet released freely turns into a projectile. Striking energy can cause material chips or painful pinches to skin. Hold the magnet firmly during installation so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the magnet. Wear safety glasses when working with powerful specimens.

Environment	Effective steel pull	Effect
Air (land)	0.75 kg	Standard
Water (riverbed)	0.86 kg (+0.11 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

*Caution: 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 limits the holding force.

3. Power loss vs temp

*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) = 0.83

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 quick installation to wood, wall, plastic, or metal. This product with a force of 0.75 kg works great as a cabinet closure, speaker holder, or spacer element in devices.

This is a crucial issue when working with model MP 5x2.7/1.2x5 C / N38. Neodymium magnets are sintered ceramics, which means they are very brittle and inelastic. One turn too many can destroy the magnet, so do it slowly. It's a good idea to use a rubber spacer under the screw head, which will cushion the stresses. 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 indoor 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. 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. Always check that the screw head is not larger than the outer diameter of the magnet (5 mm), so it doesn't protrude beyond the outline.

It is a magnetic ring with a diameter of 5 mm and thickness 5 mm. The key parameter here is the holding force amounting to approximately 0.75 kg (force ~7.31 N). The mounting hole diameter is precisely 2.7/1.2 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 as well as cons of neodymium magnets.

Pros

Besides their exceptional field intensity, neodymium magnets offer the following advantages:

They do not lose strength, even during around ten years – the decrease in lifting capacity is only ~1% (according to tests),
Neodymium magnets are characterized by highly resistant to demagnetization caused by magnetic disturbances,
By applying a lustrous coating of gold, the element gains an modern look,
The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
Thanks to flexibility in designing and the capacity to modify to individual projects,
Versatile presence in modern technologies – they are utilized in HDD drives, electric drive systems, medical equipment, also modern systems.
Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Weaknesses

Characteristics of disadvantages of neodymium magnets: tips and applications.

They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
Neodymium magnets decrease their strength 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 stability even at temperatures up to 230°C
Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in creating nuts and complex shapes in magnets, we recommend using cover - magnetic mount.
Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child safety. Additionally, small components of these magnets can disrupt the diagnostic process medical after entering the body.
Due to complex production process, their price exceeds standard values,

Lifting parameters

Magnetic strength at its maximum – what it depends on?

The declared magnet strength concerns the maximum value, obtained under laboratory conditions, namely:

with the application of a yoke made of special test steel, guaranteeing maximum field concentration
whose thickness equals approx. 10 mm
with an polished touching surface
with zero gap (without coatings)
under perpendicular force vector (90-degree angle)
at room temperature

Lifting capacity in real conditions – factors

In real-world applications, the actual holding force depends on a number of factors, listed from crucial:

Clearance – existence of any layer (rust, tape, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Base massiveness – insufficiently thick steel does not close the flux, causing part of the flux to be escaped to the other side.
Steel grade – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
Surface finish – full contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, in contrast under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

Safety rules for work with neodymium magnets

Nickel coating and allergies

Nickel alert: The nickel-copper-nickel coating contains nickel. If skin irritation appears, cease working with magnets and wear gloves.

Product not for children

Always store magnets away from children. Choking hazard is high, and the effects of magnets connecting inside the body are life-threatening.

Heat warning

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

Hand protection

Pinching hazard: The attraction force is so great that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.

Beware of splinters

Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.

Cards and drives

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

Combustion hazard

Machining of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Handling guide

Be careful. Rare earth magnets attract from a distance and snap with huge force, often quicker than you can move away.

Pacemakers

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

Keep away from electronics

Remember: neodymium magnets generate a field that confuses sensitive sensors. Maintain a safe distance from your phone, tablet, and navigation systems.
