Pulling power weakens sharply with every mm of spacing. Remember that every additional insulation layer (e.g., dirt, varnish, veneer) noticeably diminishes the holding power. Neodymiums work most effectively during direct contact; distance kills the power. Notice how rapidly the pull force plummet, when the product does not touch directly to the metal substrate. When planning the mounting, eliminate additional spacers.

The table below defines the estimated holding capacity needed to initiate the shifting of the magnet downwards along a vertical steel wall (assuming typical friction). This parameter is relative to the air gap between the magnet and the surface.

When hanging a holder on a upright surface (e.g., a fridge), it will only hold only approx. 1/5 of nominal attraction strength. Gravitational force and a low friction coefficient influence the fact that magnets move down faster than they pop off the substrate. Designing a hanger? Consider that the sliding force is noticeably lower than the perpendicular breakaway force. On a painted metal, the magnet will slide down under a significantly smaller weight. Application of an anti-slip pad can effectively raise the stability.

A too thin steel is unable to focus the full magnetic flux, which wastes potential of the magnet. If you install a neodymium to a weak sheet, the field will pass right through and the holding will be smaller. To achieve 100% of this magnet's potential, you require a sufficiently solid backing of steel. The saturation phenomenon causes that on delicate walls (e.g., appliance housings), the holder shows lower pull force. We suggest choosing the steel cross-section according to the table below.

Classic neodymiums change their properties strength above the temperature limit. Avoid high temperatures – heat can permanently destroy this product. With every degree above norm, the magnet's capacity momentarily lowers. Avoid using this product close to ovens exceeding its operating temperature limit. Too high temperature will lead to destruction of magnetism.

*Technical advisory: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) are more susceptible to demagnetization at lower temperatures than long magnets. Warning indicator in the table points to permanent field degradation for this particular item.

Two strong neodymiums interact from a significantly greater distance than a magnet and steel combination. The connection of magnet-to-magnet produces a massive flux and a wider radius of action. Designing a strong closure? Apply two magnets instead of one magnet and a striker plate. Be careful that when attracting two neodymiums, the collision energy is massive. The levitation is marginally weaker than the connection force, but still large.
*Flux density for N-N configuration drops to ~0 Gs in the exact middle between the magnets (due to field cancellation).
Attention: Estimates refer to sliding force of a pair of matching magnets (friction coefficient ~0.15 for Ni-Ni plating).

Extremely neodym field is a real danger to electronics and medical implants. These magnets produce a field that prevents correct functioning of digital equipment. Remember: the unseen radiation penetrates the body and glass. Special caution must be taken by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

Table 8: Dynamics (kinetic energy) - collision effects
MPL 20x20x20 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	17.10 km/h (4.75 m/s)	0.68 J

Magnetic elements are very brittle – a strong collision with metal risks their cracking. Watch the impact speed – a neodymium left loose turns into a projectile. Kinetic force can cause material chips or dangerous crushing to fingers. Always hold the magnet during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear eye protection when playing with large magnets.

Rust risk: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

The magnetic field penetrates through water without any losses. Buoyancy helps in lifting finds.

1. Sliding resistance

*Caution: On a vertical wall, the magnet holds only ~20% of its perpendicular strength.

2. Plate thickness effect

*Thin steel (e.g. computer case) significantly limits 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) = 0.84

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.

This product is an extremely strong plate magnet made of NdFeB material, which, with dimensions of 20x20x20 mm and a weight of 60 g, guarantees the highest quality connection. This magnetic block with a force of 151.12 N is ready for shipment in 24h, allowing for rapid realization of your project. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

Separating strong flat 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 15.40 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.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. 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 clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 20x20x20 / N38 model is magnetized through the thickness (dimension 20 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 (20x20 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: 20 mm (length), 20 mm (width), and 20 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 15.40 kg (force ~151.12 N), which, with such a flat shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Pros

Apart from their notable magnetism, neodymium magnets have these key benefits:

Their strength is durable, and after around ten years it decreases only by ~1% (according to research),
They are noted for resistance to demagnetization induced by external magnetic fields,
A magnet with a smooth nickel surface has an effective appearance,
They are known for high magnetic induction at the operating surface, which affects their effectiveness,
Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures reaching 230°C and above...
Thanks to flexibility in shaping and the ability to modify to specific needs,
Versatile presence in innovative solutions – they serve a role in magnetic memories, drive modules, medical devices, as well as technologically advanced constructions.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Weaknesses

Problematic aspects of neodymium magnets: application proposals

To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
Limited ability of creating threads in the magnet and complicated forms - recommended is a housing - mounting mechanism.
Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these devices are able to be problematic in diagnostics 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

Maximum lifting force for a neodymium magnet – what it depends on?

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

with the application of a sheet made of special test steel, ensuring maximum field concentration
whose thickness is min. 10 mm
with an ideally smooth touching surface
without the slightest clearance between the magnet and steel
for force acting at a right angle (pull-off, not shear)
in stable room temperature

Impact of factors on magnetic holding capacity in practice

Holding efficiency is influenced by working environment parameters, such as (from most important):

Distance (between the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, rust or dirt).
Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of nominal force).
Base massiveness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be escaped into the air.
Steel type – low-carbon steel attracts best. Alloy steels lower magnetic properties and lifting capacity.
Smoothness – full contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
Thermal environment – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.

Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Warnings

Bone fractures

Pinching hazard: The pulling power is so great that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.

Fragile material

Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Data carriers

Avoid bringing magnets close to a purse, laptop, or TV. The magnetic field can permanently damage these devices and erase data from cards.

Power loss in heat

Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.

Fire risk

Powder created during grinding of magnets is combustible. Do not drill into magnets unless you are an expert.

Life threat

Individuals with a ICD have to keep an safe separation from magnets. The magnetism can interfere with the operation of the life-saving device.

GPS Danger

A powerful magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Do not bring magnets close to a device to avoid breaking the sensors.

Conscious usage

Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Think ahead.

Nickel coating and allergies

A percentage of the population suffer from a sensitization to Ni, which is the standard coating for NdFeB magnets. Frequent touching might lead to dermatitis. It is best to wear protective gloves.

Choking Hazard

Always keep magnets away from children. Choking hazard is significant, and the effects of magnets clamping inside the body are very dangerous.
