Grip strength decreases drastically with every subsequent millimeter of distance. Remember that even a microscopic distance (e.g., dirt, paint, rust) noticeably diminishes the holding power. Magnetic products hold most effectively during direct contact; gap kills the power. Notice how rapidly the parameters plummet, when the product does not adhere directly to the steel surface. When planning the arrangement, eliminate redundant distances.

The following data calculates the approximate force needed to initiate the downward movement of the magnet downwards along a upright metal surface (assuming typical friction coefficient). This parameter depends on the separation distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
MP 5x2.7/1.2x5 Z / 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 pounds 225.0 g / 2.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.33 pounds 150.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.17 pounds 75.0 g / 0.7 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.38 kg / 0.83 pounds 375.0 g / 3.7 N

When mounting a holder on a upright wall (e.g., a fridge), it you can count on only approx. 20%-30% of its nominal power. Gravity and a weak degree of grip influence the fact that magnets slip faster than they pop off the substrate. Designing a wall mount? Consider that the sliding force is significantly lower than the perpendicular breakaway force. On a slippery surface, the element will give way down under a significantly smaller load. Using a rubber coating can significantly increase the grip.

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

A thin sheet cannot absorb the entire magnetic field, which weakens actual performance 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 backing of steel. The saturation effect causes that on delicate walls (e.g., appliance housings), the holder holds weaker. We suggest choosing the steel dimension according to the table below.

Standard neodymium magnets irreversibly lose parameters above the temperature limit. Protect against heat – high temperature can irreversibly damage this magnet. With increasing heat, the magnet's power briefly decreases. Refrain from using this product in hot environments exceeding its safe range. Ignoring the limit will result in destruction of magnetic properties.

*Engineering note: Temperature resistance is determined by both grade, as well as the dimension ratios. Low-profile magnets (low Pc) are more susceptible to demagnetization under lower heat stress than long magnets. Red status in the table indicates permanent field degradation for this specific geometry.

Two magnets attract each other from a significantly greater distance than a magnet and steel combination. The connection of two magnets generates a stronger field and a wider radius of performance. Planning to create a strong closure? Apply two magnets instead of one magnet and a steel. Be careful that when bringing together two magnets, the impact force is massive. The levitation is marginally weaker than the connection force, but still significant.
*Field value between like poles reaches ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Attention: Figures show friction force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field is a real danger to electronics and medical implants. These NdFeB products generate a field that destroys function of sensitive medical devices. Remember: the invisible magnetic field penetrates the body and plastic. Increased vigilance must be exercised by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, car keys, speakers, and displays. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Neodymium magnets are delicate – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Striking energy can cause material chips or painful pinches to skin. Be sure to control the product during installation so it doesn't hit violently against the steel surface. A collision at high speed almost guarantees destruction of the magnet. Wear eye protection when handling 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. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Warning: On a vertical surface, the magnet retains merely ~20% of its perpendicular strength.

2. Efficiency vs thickness

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

3. Thermal stability

*For standard magnets, the critical 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.

The ring magnet with a hole MP 5x2.7/1.2x5 Z / N38 is created for mechanical fastening, where glue might fail or be insufficient. Thanks to the hole (often for a screw), this model enables easy screwing to wood, wall, plastic, or metal. This product with a force of 0.75 kg works great as a door latch, speaker holder, or spacer element in devices.

This is a crucial issue when working with model MP 5x2.7/1.2x5 Z / 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. 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 is not sufficient for rain. Damage to the protective layer during assembly is the most common cause of rusting. 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. 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.

The presented product is a ring magnet with dimensions Ø5 mm (outer diameter) and height 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. In the case of connecting two rings, make sure one is turned the right way. When ordering a larger quantity, magnets are usually packed in stacks, where they are already naturally paired.

Pros as well as cons of rare earth magnets.

Advantages

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

They retain magnetic properties for nearly 10 years – the loss is just ~1% (according to analyses),
They possess excellent resistance to magnetic field loss due to external magnetic sources,
In other words, due to the metallic surface of nickel, the element gains a professional look,
Neodymium magnets generate maximum magnetic induction on a small surface, which ensures high operational effectiveness,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Possibility of custom creating as well as adapting to specific needs,
Significant place in future technologies – they are commonly used in mass storage devices, electric drive systems, medical equipment, and other advanced devices.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Problematic aspects of neodymium magnets and proposals for their use:

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 decrease their power 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 durability even at temperatures up to 230°C
They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating nuts and complex shapes in magnets, we propose using a housing - magnetic holder.
Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these devices can disrupt the diagnostic process medical in case of swallowing.
With mass production the cost of neodymium magnets can be a barrier,

Lifting parameters

Maximum magnetic pulling force – what it depends on?

The load parameter shown represents the limit force, measured under optimal environment, namely:

with the use of a sheet made of special test steel, guaranteeing maximum field concentration
possessing a thickness of minimum 10 mm to avoid saturation
with a plane perfectly flat
with zero gap (no coatings)
for force acting at a right angle (in the magnet axis)
at room temperature

Practical lifting capacity: influencing factors

In real-world applications, the actual holding force results from a number of factors, presented from the most important:

Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Material type – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
Surface structure – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.

Precautions when working with neodymium magnets

Allergy Warning

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness appears, cease handling magnets and wear gloves.

Bone fractures

Watch your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!

Medical interference

Life threat: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.

Fragile material

Neodymium magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets leads to them breaking into shards.

Handling rules

Use magnets consciously. Their powerful strength can shock even professionals. Be vigilant and respect their force.

Operating temperature

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its properties and pulling force.

GPS and phone interference

GPS units and mobile phones are extremely sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the internal compass in your phone.

Threat to electronics

Intense magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.

Fire risk

Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.

Product not for children

Absolutely keep magnets out of reach of children. Ingestion danger is high, and the effects of magnets clamping inside the body are very dangerous.
