Frequently asked questions

How much will a block magnet really hold?

The catalogue force is measured in full contact with smooth steel at least 10 mm thick, pulled perpendicular, at about 20 °C. On 1 mm sheet about 50% of that value remains, on 0.5 mm about 25%. Mounted on a vertical wall the realistic figure is 20–30%, because the load is then in shear rather than in tension.

What is the maximum working temperature?

Standard N-series grades up to 80 °C, and N50, N52 and N54 up to 60 °C. Above the maximum working temperature the loss stops being reversible. The Curie temperature, at which magnetic properties are lost completely, is about 310 °C.

What safety factor should I allow?

At least twice the mass of the item, and three to five times for vertical mounting. The margin covers sheet thickness, surface condition, any layer of paint or rust, and vibration.

Magnetic force decreases sharply per each millimeter of gap. Remember that even a very thin break (e.g., dirt, paint, veneer) strongly reduces the pull force. Neodymiums operate most effectively during direct contact; air break nullifies the force. Analyze how flashily the pull force plummet, when the magnet does not touch directly to the metal substrate. When planning the mounting, discard unnecessary gaps.

This section defines the estimated force needed to start the sliding of the magnet down against a vertical metal surface (considering typical friction). This value depends on the air gap between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull
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 surface (e.g., a car body), it will only hold barely about 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip influence the fact that magnets slip faster than they detach. Designing a wall mount? Note that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the magnet will give way down under a noticeably lighter weight. Using a rubber layer can drastically improve the result.

Table 4: Material efficiency (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

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

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 thin sheet is incapable of focus the full magnetic flux, which weakens actual performance of the magnet. If you mount a strong magnet to a weak sheet, the flux will penetrate right through and the attraction force will be weaker. To utilize the maximum of this magnet's power, you need a suitably thick element of steel. The saturation phenomenon causes that on sheet metal structures (e.g., thin profiles), the product works worse. We recommend selecting the steel dimension from these parameters.

Standard neodymium magnets irreversibly lose power after exceeding the maximum temperature. Protect against heat – high temperature can permanently damage this magnet. With increasing heat, the neodymium's capacity momentarily lowers. Refrain from using this magnet in hot environments higher than its working range. Too high temperature will result in permanent loss of magnetism.

*Important note: Temperature resistance is determined by both grade, but also on the magnet's shape. Thin magnets (low Pc) are more susceptible to demagnetization sooner compared to rod magnets. The danger warning in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a much further distance than a neodymium and metal setup. The connection of magnet-to-magnet generates a stronger field and a larger range of performance. Designing a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the pinch force is massive. The levitation is slightly lower than the connection force, but still large.
*Flux density for N-N configuration drops to ~0 Gs at the midpoint of the gap (caused by magnetic field nullification).
Attention: Estimates refer to sliding force of a pair of same magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field poses a real danger to electronics as well as medical implants. These neodymiums generate a field that disrupts operation of sensitive medical devices. Remember: the unseen radiation penetrates the body and housings. Increased vigilance must be exercised by people with hearing aids and insulin pumps. The risk also applies to: mechanical watches, car keys, membranes, and screens. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a violent impact against metal causes immediate chipping. Watch the impact speed – a neodymium left loose speeds with massive force. Impact energy can trigger coating fragments or injury to fingers. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear safety glasses when playing 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. However, remember the water resistance when pulling the rope quickly.

1. Sliding resistance

*Caution: On a vertical wall, the magnet holds only a fraction of its max power.

2. Efficiency vs thickness

*Thin metal sheet (e.g. computer case) severely weakens the holding force.

3. Power loss vs temp

*For N38 grade, the max working temp 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.

MPL 40x18x10 / N38 - lamellar magnet

30.75 zł brutto / pcs

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 premium class connection. This magnetic block with a force of 2.29 N is ready for shipment in 24h, allowing for rapid realization of your project. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

The key to success is shifting the magnets along their largest connection plane (using e.g., the edge of a table), which is easier than trying to tear them apart directly. 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 fasteners 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, we recommend utilizing 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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. This is the most popular configuration for block magnets used in separators and holders.

The presented product is a neodymium magnet with precisely defined parameters: 3 mm (length), 3 mm (width), and 1 mm (thickness). The key parameter here is the holding force amounting to approximately 0.23 kg (force ~2.29 N), which, with such a compact shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of neodymium magnets.

Benefits

Besides their remarkable magnetic power, neodymium magnets offer the following advantages:

They virtually do not lose strength, because even after ten years the performance loss is only ~1% (based on calculations),
Neodymium magnets remain extremely resistant to magnetic field loss caused by magnetic disturbances,
The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to present itself better,
Neodymium magnets create maximum magnetic induction on a contact point, which ensures high operational effectiveness,
Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
Possibility of custom modeling and adapting to precise applications,
Huge importance in future technologies – they are commonly used in data components, brushless drives, precision medical tools, and complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in small systems

Limitations

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in realizing threads and complicated shapes in magnets, we propose using casing - magnetic mechanism.
Health risk resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

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

The force parameter is a result of laboratory testing executed under specific, ideal conditions:

with the application of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
with a thickness no less than 10 mm
with an ground contact surface
with total lack of distance (no impurities)
for force acting at a right angle (pull-off, not shear)
at conditions approx. 20°C

Lifting capacity in practice – influencing factors

Effective lifting capacity impacted by specific conditions, such as (from most important):

Distance – the presence of foreign body (paint, tape, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
Material type – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity was assessed by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.

Warnings

Warning for heart patients

Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.

Handling guide

Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.

Sensitization to coating

A percentage of the population suffer from a hypersensitivity to nickel, which is the standard coating for neodymium magnets. Prolonged contact can result in skin redness. It is best to wear safety gloves.

Fire risk

Fire warning: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.

Fragile material

Watch out for shards. Magnets can fracture upon violent connection, launching sharp fragments into the air. Wear goggles.

Physical harm

Pinching hazard: The attraction force is so great that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.

Thermal limits

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

Precision electronics

A powerful magnetic field disrupts the functioning of compasses in phones and GPS navigation. Do not bring magnets near a device to prevent breaking the sensors.

Keep away from children

Absolutely store magnets away from children. Choking hazard is high, and the effects of magnets clamping inside the body are fatal.

Electronic devices

Powerful magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.
