Magnetic force drops drastically with every mm of spacing. Remember that every additional insulation layer (e.g., contamination, varnish, veneer) strongly diminishes the holding power. Magnetic products work most effectively during direct contact; air break nullifies the force. Observe how rapidly the parameters plummet, when the product does not adhere flatly to the steel surface. When designing the mounting, avoid additional spacers.

The table below presents the approximate holding capacity necessary to start the sliding of the magnet downwards against a vertical steel wall (assuming typical friction). The holding force varies with the air gap between the magnet and the surface.

Table 3: Vertical assembly (sliding) - behavior on slippery surfaces
MPL 3x3x1 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.07 kg / 0.15 lbs 69.0 g / 0.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.05 kg / 0.10 lbs 46.0 g / 0.5 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.02 kg / 0.05 lbs 23.0 g / 0.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.12 kg / 0.25 lbs 115.0 g / 1.1 N

When hanging a magnet on a vertical plane (e.g., a board), it will only hold barely about 1/5 of its maximum pull force. Gravity as well as a low friction coefficient mean that holders slip easier than they pull off. Designing a hanger? Consider that the sliding force is noticeably lower than the perpendicular breakaway force. On a painted metal, the holder will slip down under a significantly smaller weight. Application of an anti-slip pad can effectively increase the grip.

Table 4: Steel thickness (saturation) - sheet metal selection
MPL 3x3x1 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.02 kg / 0.05 lbs 23.0 g / 0.2 N
1 mm	25%	0.06 kg / 0.13 lbs 57.5 g / 0.6 N
2 mm	50%	0.12 kg / 0.25 lbs 115.0 g / 1.1 N
3 mm	75%	0.17 kg / 0.38 lbs 172.5 g / 1.7 N
5 mm	100%	0.23 kg / 0.51 lbs 230.0 g / 2.3 N
10 mm	100%	0.23 kg / 0.51 lbs 230.0 g / 2.3 N
11 mm	100%	0.23 kg / 0.51 lbs 230.0 g / 2.3 N
12 mm	100%	0.23 kg / 0.51 lbs 230.0 g / 2.3 N

A too thin steel is unable to take in the entire magnetic field, which wastes potential of the holder. Should you attach a powerful product to a too thin substrate, the flux will penetrate right through and the pull force will drop sharply. To squeeze the maximum of this magnet's potential, you require a sufficiently solid backing of metal. The material oversaturation causes that on thin elements (e.g., thin profiles), the product works worse. We recommend selecting the steel thickness based on the following data.

100 °C	-28.8%	0.16 kg / 0.36 lbs 163.8 g / 1.6 N

Standard neodymium magnets irreversibly lose strength after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly demagnetize this magnet. With every degree above norm, the neodymium's force briefly lowers. Avoid using this product close to heaters higher than its operating temperature limit. Exceeding the critical threshold will result in irreversible degradation of magnetism.

*Technical advisory: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) may lose charge permanently sooner than taller cylinders. Red status in the table signals a risk of irreversible loss for this particular item.

Two strong neodymiums interact from a wider radius than a neodymium and metal setup. The connection of two magnets produces a massive flux and a wider radius of action. Designing a powerful holder? Apply two magnets instead of a neodymium and a striker plate. Exercise caution that when connecting a pair of magnets, the impact force is massive. The repulsion force is slightly lower than the attraction, but still large.
*The magnetic induction between like poles reaches ~0 Gs at the midpoint between the magnets (due to field cancellation).
Attention: Results apply to friction force of two same magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field poses a large risk to electronics and medical implants. These magnets produce a flux that disrupts operation of sensitive medical devices. Notice: the invisible magnetic field penetrates the body and plastic. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. Influence will be felt by: automatic timepieces, remotes, membranes, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Collisions (kinetic energy) - collision effects
MPL 3x3x1 / N38

Start from (mm)	Speed (km/h)	Energy (J)

Magnetic elements are prone to chipping – a strong collision with metal can result in shattering. Watch the impact speed – a magnet released freely becomes dangerous. Impact energy can destroy the magnet or dangerous crushing to skin. Be sure to control the product during bringing near metal so it doesn't slam with momentum against the steel surface. A collision at high speed means shattering of the neodymium. Wear eye protection when working with powerful specimens.

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

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

2. Steel saturation

*Thin steel (e.g. 0.5mm PC case) drastically limits 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) = 0.40

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.

This product is a very powerful plate magnet made of NdFeB material, which, with dimensions of 3x3x1 mm and a weight of 0.07 g, guarantees the highest quality connection. This magnetic block with a force of 2.29 N is ready for shipment in 24h, allowing for rapid realization of your project. Additionally, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.

Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. Watch your fingers! Magnets with a force of 0.23 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

They constitute a key element in the production of wind generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 3x3x1 / N38, it is best to use strong epoxy glues (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Remember to roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 3x3x1 / N38 model is magnetized axially (dimension 1 mm), which means that the N and S poles are located on its largest, flat surfaces. In practice, this means that this magnet has the greatest attraction force on its main planes (3x3 mm), which is ideal for flat mounting. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

The presented product is a neodymium magnet with precisely defined parameters: 3 mm (length), 3 mm (width), and 1 mm (thickness). It is a magnetic block with dimensions 3x3x1 mm and a self-weight of 0.07 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of neodymium magnets.

Advantages

Besides their stability, neodymium magnets are valued for these benefits:

They retain magnetic properties for nearly ten years – the drop is just ~1% (in theory),
They possess excellent resistance to magnetism drop when exposed to external magnetic sources,
The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
Magnets possess huge magnetic induction on the working surface,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
Thanks to versatility in shaping and the ability to adapt to unusual requirements,
Versatile presence in high-tech industry – they are used in HDD drives, motor assemblies, advanced medical instruments, also technologically advanced constructions.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Weaknesses

Problematic aspects of neodymium magnets: application proposals

They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields 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 power 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. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
We recommend a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex shapes.
Potential hazard resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the context of child safety. Additionally, small elements of these products are able to complicate diagnosis medical in case of swallowing.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

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

The lifting capacity listed is a theoretical maximum value performed under the following configuration:

with the application of a yoke made of low-carbon steel, ensuring maximum field concentration
whose transverse dimension reaches at least 10 mm
characterized by smoothness
with zero gap (no paint)
under axial application of breakaway force (90-degree angle)
in stable room temperature

Determinants of practical lifting force of a magnet

It is worth knowing that the magnet holding may be lower depending on the following factors, starting with the most relevant:

Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
Steel grade – ideal substrate is pure iron steel. Stainless steels may attract less.
Surface structure – the smoother and more polished the surface, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Warnings

Nickel allergy

Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation appears, immediately stop handling magnets and use protective gear.

Medical interference

Patients with a pacemaker have to maintain an large gap from magnets. The magnetism can interfere with the functioning of the life-saving device.

Hand protection

Danger of trauma: The attraction force is so great that it can result in hematomas, crushing, and even bone fractures. Use thick gloves.

Caution required

Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.

Combustion hazard

Powder generated during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Fragile material

Neodymium magnets are ceramic materials, which means they are fragile like glass. Clashing of two magnets leads to them cracking into small pieces.

Heat warning

Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. This process is irreversible.

GPS Danger

An intense magnetic field negatively affects the operation of compasses in phones and navigation systems. Maintain magnets close to a smartphone to avoid breaking the sensors.

Safe distance

Very strong magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.

Swallowing risk

Always store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are fatal.
