Magnetic force decreases significantly per each millimeter of gap. Remember that every additional insulation layer (e.g., contamination, paint, rust) strongly reduces the pull force. Magnetic products hold optimally during direct contact; gap kills the force. Notice how quickly the parameters drop, when the magnet does not adhere directly to the metal substrate. When planning the assembly, eliminate redundant distances.

This section shows the approximate holding capacity required to start the sliding of the magnet down on a vertical steel wall (considering standard friction coefficient). This value varies with the distance between the magnet and the metal.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MP 5x1.5x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.23 kg / 0.51 pounds 231.0 g / 2.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.15 kg / 0.34 pounds 154.0 g / 1.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.08 kg / 0.17 pounds 77.0 g / 0.8 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.39 kg / 0.85 pounds 385.0 g / 3.8 N

When placing a element on a upright plane (e.g., a fridge), it you can count on barely about 20%-30% of nominal attraction strength. Gravitational force and a weak degree of grip mean that products slide down easier than they pull off. Want to create a wall mount? Remember that the sliding force is significantly lower than the maximum static pull force. On a painted metal, the holder will slide down under a much lighter load. Using a rubber coating can significantly improve the result.

Table 4: Material efficiency (saturation) - power losses
MP 5x1.5x3 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.08 kg / 0.17 pounds 77.0 g / 0.8 N
1 mm	25%	0.19 kg / 0.42 pounds 192.5 g / 1.9 N
2 mm	50%	0.39 kg / 0.85 pounds 385.0 g / 3.8 N
3 mm	75%	0.58 kg / 1.27 pounds 577.5 g / 5.7 N
5 mm	100%	0.77 kg / 1.70 pounds 770.0 g / 7.6 N
10 mm	100%	0.77 kg / 1.70 pounds 770.0 g / 7.6 N
11 mm	100%	0.77 kg / 1.70 pounds 770.0 g / 7.6 N
12 mm	100%	0.77 kg / 1.70 pounds 770.0 g / 7.6 N

A thin metal plate cannot focus the full magnetic flux, which wastes potential of the holder. If you mount a strong magnet to a too thin substrate, the field will pass right through and the pull force will drop sharply. To utilize full efficiency of this magnet's power, you require a sufficiently solid element of steel. The saturation effect causes that on sheet metal structures (e.g., thin profiles), the holder holds weaker. We suggest choosing the steel thickness based on the following data.

Table 5: Thermal stability (material behavior) - thermal limit
MP 5x1.5x3 / N38

40 °C	-2.2%	0.75 kg / 1.66 pounds 753.1 g / 7.4 N	OK

Ordinary NdFeB products irreversibly lose power after exceeding the maximum temperature. Avoid high temperatures – excessive heat can irreversibly destroy this product. With increasing heat, the neodymium's power temporarily drops. Avoid using this magnet close to ovens exceeding its operating temperature limit. Too high temperature will result in irreversible degradation of magnetic properties.

*Engineering note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) may lose charge permanently sooner compared to rod magnets. Warning indicator in the table points to permanent field degradation for this particular item.

Two magnetic products attract each other from a wider radius than a magnet and sheet combination. The connection of magnet-to-magnet produces a massive flux and a wider radius of operation. Planning to create a strong closure? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when attracting two neodymiums, the impact force is massive. The repulsion force is a bit weaker than the connection force, but still significant.
*Flux density in repulsion mode reaches ~0 Gs at the geometric center between the magnets (due to field cancellation).
Note: Results apply to friction force of dual matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field poses a serious hazard to IT equipment as well as medical implants. These magnets generate a field that disrupts operation of digital equipment. Remember: the invisible magnetic field penetrates the body and plastic. Special caution must be exercised by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, car keys, membranes, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a collision with steel causes immediate chipping. Pay attention to connection velocity – a magnet released freely speeds with massive force. Impact energy can destroy the magnet or injury to skin. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the metal. A collision at high speed means shattering of the neodymium. Wear safety glasses when playing with large magnets.

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. 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 surface, the magnet retains just approx. 20-30% of its max power.

2. Plate thickness effect

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

3. Power loss vs temp

*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) = 1.66

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. 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 0.77 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 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. 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 magnets in hermetic housing or additional protection with varnish.

A screw or bolt with a thread diameter smaller than 1.5 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.

It is a magnetic ring with a diameter of 5 mm and thickness 3 mm. The pulling force of this model is an impressive 0.77 kg, which translates to 7.50 N in newtons. The mounting hole diameter is precisely 1.5 mm.

The poles are located on the planes with holes, not on the sides of the ring. 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.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Strengths

Besides their high retention, neodymium magnets are valued for these benefits:

They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (based on calculations),
Magnets very well protect themselves against demagnetization caused by external fields,
By using a shiny layer of gold, the element has an nice look,
Neodymium magnets create maximum magnetic induction on a small surface, which ensures high operational effectiveness,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures reaching 230°C and above...
Possibility of exact machining as well as modifying to individual requirements,
Key role in high-tech industry – they are utilized in hard drives, electric motors, diagnostic systems, and technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which allows their use in small systems

Disadvantages

Disadvantages of NdFeB magnets:

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. 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 strength. 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
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
Limited possibility of producing threads in the magnet and complicated shapes - preferred is cover - magnet mounting.
Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small elements of these devices can disrupt the diagnostic process medical when they are in the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Maximum lifting capacity of the magnet – what contributes to it?

The specified lifting capacity represents the limit force, measured under laboratory conditions, namely:

with the application of a yoke made of low-carbon steel, ensuring maximum field concentration
with a cross-section of at least 10 mm
with a plane free of scratches
with direct contact (without impurities)
for force acting at a right angle (pull-off, not shear)
at standard ambient temperature

Lifting capacity in real conditions – factors

Please note that the magnet holding may be lower depending on the following factors, starting with the most relevant:

Clearance – existence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of nominal force).
Base massiveness – insufficiently thick sheet does not close the flux, causing part of the flux to be escaped to the other side.
Metal type – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
Surface condition – ground elements ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.

Safety rules for work with NdFeB magnets

Skin irritation risks

Certain individuals experience a sensitization to Ni, which is the common plating for neodymium magnets. Frequent touching can result in skin redness. We suggest wear protective gloves.

Respect the power

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

Power loss in heat

Do not overheat. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).

Precision electronics

An intense magnetic field interferes with the operation of magnetometers in phones and navigation systems. Do not bring magnets near a device to prevent damaging the sensors.

Product not for children

NdFeB magnets are not toys. Swallowing several magnets may result in them attracting across intestines, which constitutes a critical condition and necessitates urgent medical intervention.

Health Danger

Individuals with a heart stimulator should maintain an large gap from magnets. The magnetism can interfere with the operation of the life-saving device.

Risk of cracking

Neodymium magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets will cause them breaking into small pieces.

Finger safety

Big blocks can break fingers instantly. Do not place your hand between two strong magnets.

Data carriers

Powerful magnetic fields can destroy records on credit cards, HDDs, and storage devices. Keep a distance of min. 10 cm.

Fire warning

Fire warning: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.
