Grip strength decreases sharply per each millimeter of distance. Remember that every additional insulation layer (e.g., dirt, varnish, veneer) noticeably diminishes the holding power. Magnetic products hold optimally during direct contact; air break drastically cuts the power. Analyze how flashily the load capacity fall, when the product does not touch tightly to the steel surface. When planning the assembly, eliminate unnecessary gaps.

This section indicates the estimated force needed to cause the sliding of the magnet downwards along a upright metal surface (assuming standard friction coefficient). This value varies with the air gap between the magnet and the metal.

When hanging a holder on a upright wall (e.g., a fridge), it will only hold only approx. 1/5 of nominal attraction strength. Gravitational force and a weak degree of grip influence the fact that holders move down faster than they pull off. Designing a vertical fastening? Consider that the shear force is much weaker than the perpendicular breakaway force. On a painted metal, the holder will slide down under a noticeably lighter cargo. Using a rubber coating can effectively increase the grip.

A thin sheet is not enough to focus the full magnetic flux, which wastes potential of the holder. If you mount a strong magnet to a thin surface, the magnetism will pass right through and the pull force will drop sharply. To achieve the maximum of this magnet's power, you require a sufficiently solid piece of metal. The material oversaturation causes that on thin elements (e.g., thin profiles), the product works worse. We advise picking the steel cross-section based on the following data.

Classic neodymiums irreversibly lose power past the thermal threshold. Watch out for overheating – high temperature can irreversibly destroy this product. With increasing heat, the magnet's force briefly drops. Avoid using this product in hot environments higher than its safe range. Ignoring the limit will lead to irreversible degradation of magnetism.

*Technical advisory: Heat tolerance depends not only on the material grade, as well as the dimension ratios. Flat 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 significantly greater distance than a magnet and steel setup. The setup of magnet-to-magnet produces a massive flux and a wider radius of performance. Planning to create a solid fastener? Utilize two neodymiums instead of one magnet and a striker plate. Be careful that when connecting a pair of magnets, the impact force is huge. The levitation is marginally weaker than the connection force, but still large.
*Flux density between like poles is approximately ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
* Estimates demonstrate friction force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field is a real danger to electronic devices as well as medical implants. These NdFeB products generate a flux that prevents correct functioning of digital equipment. Remember: the unseen radiation acts through matter and housings. Exceptional care must be exercised by people with hearing aids and drug dispensers. Influence will be felt by: automatic timepieces, car keys, speakers, and screens. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

50 mm	39.36 km/h (10.93 m/s)	3.36 J
100 mm	55.61 km/h (15.45 m/s)	6.72 J

NdFeB products are delicate – a strong collision with metal causes immediate chipping. Control the attraction moment – a neodymium left loose speeds with massive force. Kinetic force can cause material chips or dangerous crushing to skin. Always hold the magnet during mounting so it doesn't slam with momentum against the metal. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when playing with powerful specimens.

Rust risk: 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

*Caution: On a vertical surface, the magnet holds merely approx. 20-30% of its max power.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) severely weakens the holding force.

3. Power loss vs temp

*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) = 0.26

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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. 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. 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 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 11/6 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 Ø36.2x7.5 mm and a weight of 56.3 g. The key parameter here is the lifting capacity amounting to approximately 17.12 kg (force ~167.95 N). The product has a [NiCuNi] coating and is made of NdFeB material. Inner hole dimension: 11/6 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.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Advantages

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

Their magnetic field remains stable, and after around 10 years it drops only by ~1% (theoretically),
They possess excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
They feature high magnetic induction at the operating surface, making them more effective,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
Possibility of individual creating as well as adapting to defined applications,
Key role in high-tech industry – they are used in computer drives, electric motors, advanced medical instruments, and multitasking production systems.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Cons

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

They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
When exposed to high temperature, neodymium magnets experience 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
They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
We recommend a housing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated shapes.
Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these products can be problematic in diagnostics medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Optimal lifting capacity of a neodymium magnet – what contributes to it?

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

on a base made of mild steel, optimally conducting the magnetic flux
with a cross-section minimum 10 mm
with a surface free of scratches
without any insulating layer between the magnet and steel
for force acting at a right angle (in the magnet axis)
at room temperature

Lifting capacity in real conditions – factors

Real force is influenced by specific conditions, mainly (from most important):

Gap (between the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
Angle of force application – highest force is available only during perpendicular pulling. The shear force of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
Steel thickness – too thin sheet does not accept the full field, causing part of the flux to be lost into the air.
Metal type – different alloys attracts identically. High carbon content weaken the attraction effect.
Surface condition – smooth surfaces ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

Lifting capacity was measured with the use of a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Safe handling of neodymium magnets

Powerful field

Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.

Demagnetization risk

Keep cool. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).

Allergy Warning

Certain individuals experience a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Extended handling may cause a rash. We suggest wear safety gloves.

Medical implants

Individuals with a pacemaker should keep an large gap from magnets. The magnetic field can disrupt the functioning of the life-saving device.

Swallowing risk

Neodymium magnets are not intended for children. Accidental ingestion of multiple magnets can lead to them attracting across intestines, which poses a direct threat to life and necessitates urgent medical intervention.

Keep away from computers

Do not bring magnets near a purse, laptop, or TV. The magnetic field can destroy these devices and erase data from cards.

Compass and GPS

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

Fire warning

Dust generated during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.

Bodily injuries

Protect your hands. Two powerful magnets will snap together immediately with a force of massive weight, crushing anything in their path. Be careful!

Shattering risk

Neodymium magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets leads to them cracking into small pieces.

Security! Learn more about hazards in the article: Magnet Safety Guide.
