Magnetic force weakens sharply with every mm of distance. Note that every additional insulation layer (e.g., dirt, varnish, veneer) noticeably weakens the grip. Neodymiums work strongest in perfect adhesion; air break nullifies the power. Notice how flashily the load capacity fall, when the product does not touch tightly to the metal substrate. When calculating the arrangement, eliminate redundant distances.

The table below defines the approximate holding capacity sufficient to initiate the downward movement of the magnet down against a upright metal surface (considering standard friction). This value varies with the distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - behavior on slippery surfaces
MP 5x2.7/1.2x5 C / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
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
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.17 lbs 75.0 g / 0.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.38 kg / 0.83 lbs 375.0 g / 3.7 N

When mounting a element on a upright wall (e.g., a car body), it you can count on only about 20%-30% of its nominal power. Gravity as well as a low friction coefficient cause that holders slide down easier than they pop off the substrate. Planning a wall mount? Remember that the shear force is much weaker than the maximum static pull force. On a smooth steel, the element will slip down under a noticeably lighter weight. Application of an anti-slip coating can drastically increase the grip.

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

A thin metal plate is unable to absorb the entire magnetic field, which weakens actual performance of the holder. Should you attach a powerful product to a thin surface, the field will penetrate right through and the attraction force will be weaker. To squeeze the maximum of this magnet's potential, you require a sufficiently solid element of steel. The saturation phenomenon causes that on thin elements (e.g., thin profiles), the magnet shows lower pull force. We suggest choosing the steel dimension based on the following data.

Standard neodymium magnets lose strength above the temperature limit. Avoid high temperatures – high temperature can permanently demagnetize this magnet. With every degree above norm, the neodymium's power temporarily drops. Refrain from using this magnet close to heaters exceeding its operating temperature limit. Ignoring the limit will lead to destruction of magnetic properties.

*Technical advisory: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Flat magnets (low permeance coefficient) may lose charge permanently sooner than taller cylinders. Warning indicator in the table indicates permanent field degradation for this particular item.

Two magnetic products interact from a significantly greater distance than a neodymium and metal combination. Such a system of magnet-to-magnet creates a more powerful interaction and a larger range of action. Designing a solid fastener? Utilize two neodymiums instead of one magnet and a steel. Exercise caution that when bringing together two magnets, the collision energy is massive. The levitation is slightly lower than the connection force, but still large.
*The magnetic induction between like poles is approximately ~0 Gs in the exact middle of the gap (resulting from vector opposition).
Important: Calculations refer to friction force of two matching neodymium magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation poses a serious hazard to IT equipment as well as pacemakers. These neodymiums produce a flux that destroys function of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and plastic. Exceptional care must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, speakers, and displays. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

NdFeB products are prone to chipping – a violent impact against metal can result in shattering. Pay attention to connection velocity – a magnet released freely turns into a projectile. Kinetic force can cause material chips or injury to skin. Hold the magnet firmly during mounting so it doesn't slam with momentum against the steel surface. A collision at high speed ends with a crack of the magnet. Use safety goggles when handling with powerful specimens.

Corrosion warning: 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

*Warning: On a vertical wall, the magnet holds merely approx. 20-30% of its nominal pull.

2. Steel saturation

*Thin metal sheet (e.g. 0.5mm PC case) drastically limits the holding force.

3. Thermal stability

*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) = 0.83

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. 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 5x2.7/1.2x5 C / N38. Neodymium magnets are sintered ceramics, which means they are hard but breakable 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.

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. This product is dedicated for indoor use. For outdoor applications, we recommend choosing magnets in hermetic housing or additional protection with varnish.

A screw or bolt with a thread diameter smaller than 2.7/1.2 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 (5 mm), so it doesn't protrude beyond the outline.

This model is characterized by dimensions Ø5x5 mm and a weight of 0.69 g. The pulling force of this model is an impressive 0.75 kg, which translates to 7.31 N in newtons. 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. In the case of connecting two rings, make sure one is turned the right way. We do not offer paired sets with marked poles in this category, but they are easy to match manually.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Benefits

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

They have stable power, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
They possess excellent resistance to magnetism drop when exposed to external magnetic sources,
By applying a lustrous layer of gold, the element gains an nice look,
Neodymium magnets create maximum magnetic induction on a their surface, which allows for strong attraction,
Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
Thanks to modularity in designing and the ability to modify to complex applications,
Key role in high-tech industry – they are utilized in hard drives, electromotive mechanisms, precision medical tools, as well as technologically advanced constructions.
Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Weaknesses

Disadvantages of NdFeB magnets:

Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
Neodymium magnets decrease their strength 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
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Limited ability of making nuts in the magnet and complicated shapes - preferred is casing - mounting mechanism.
Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these devices can be problematic in diagnostics medical after entering the body.
With budget limitations the cost of neodymium magnets can be a barrier,

Pull force analysis

Breakaway strength of the magnet in ideal conditions – what it depends on?

The declared magnet strength concerns the limit force, recorded under laboratory conditions, specifically:

on a plate made of mild steel, perfectly concentrating the magnetic flux
whose transverse dimension equals approx. 10 mm
characterized by lack of roughness
under conditions of gap-free contact (surface-to-surface)
for force applied at a right angle (in the magnet axis)
at room temperature

Practical aspects of lifting capacity – factors

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

Distance – existence of foreign body (rust, tape, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
Load vector – maximum parameter is reached only during perpendicular pulling. The shear force of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
Steel grade – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
Base smoothness – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
Temperature – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was determined using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet and the plate lowers the holding force.

Precautions when working with neodymium magnets

Serious injuries

Protect your hands. Two large magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!

Magnetic media

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

Keep away from children

Strictly store magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are life-threatening.

Compass and GPS

GPS units and mobile phones are highly susceptible to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.

Beware of splinters

Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Do not overheat magnets

Regular neodymium magnets (grade N) lose power when the temperature exceeds 80°C. This process is irreversible.

Do not underestimate power

Handle with care. Neodymium magnets attract from a distance and snap with massive power, often quicker than you can react.

Nickel allergy

It is widely known that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands or opt for coated magnets.

Flammability

Powder created during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

ICD Warning

Medical warning: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
