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.

Grip strength weakens significantly with every mm of distance. Keep in mind that every additional insulation layer (e.g., dirt, varnish, rust) noticeably diminishes the holding power. Neodymiums hold strongest during direct contact; gap drastically cuts the force. Notice how quickly the pull force drop, when the product does not touch flatly to the metal substrate. When designing the assembly, eliminate additional spacers.

When hanging a magnet on a upright plane (e.g., a fridge), it will maintain only about 20%-30% of its nominal power. Gravitational force and a weak degree of grip mean that products move down faster than they pull off. Designing a vertical fastening? Consider that the sliding force is much weaker than the perpendicular breakaway force. On a painted metal, the magnet will slip down under a much lighter weight. Using a rubber layer can effectively raise the stability.

A thin metal plate is not enough to absorb the full magnetic flux, which squanders power of the holder. If you attach a powerful product to a thin surface, the flux will penetrate right through and the holding will be smaller. To squeeze full efficiency of this magnet's power, you require a sufficiently solid element of metal. The saturation effect means that on thin elements (e.g., thin profiles), the product holds weaker. We suggest choosing the steel thickness based on the following data.

Standard neodymium magnets change their properties parameters after exceeding the maximum temperature. Watch out for overheating – excessive heat can permanently demagnetize this product. With increasing heat, the magnet's force temporarily lowers. Refrain from using this product close to heaters higher than its operating temperature limit. Ignoring the limit will cause destruction of magnetic properties.
*Important note: Temperature resistance is determined by both grade, but also on the magnet's shape. Flat magnets (low Pc) are more susceptible to demagnetization at lower temperatures than taller cylinders. The danger warning in the table points to permanent field degradation for this particular item.

Two strong neodymiums interact from a much further distance than a neodymium and metal setup. Such a system of magnet-to-magnet produces a massive flux and a larger range of performance. Want to build a powerful holder? Use a pair of magnets instead of a neodymium and a steel. Remember that when attracting two neodymiums, the pinch force is extreme. The repulsion force is a bit weaker than the connection force, but still large.
*Flux density for N-N configuration reaches ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
* Figures refer to friction force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

Extremely neodym field is a large risk to IT equipment as well as medical implants. These neodymiums generate a field that disrupts operation of sensitive medical devices. Be aware: the unseen radiation penetrates the body and housings. Exceptional care must be exercised by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, car keys, speakers, and screens. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Neodymium magnets are prone to chipping – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely turns into a projectile. Impact energy can destroy the magnet or painful pinches to fingers. Hold the magnet firmly during mounting so it doesn't hit with great force against the metal. A collision at high speed means shattering of the magnet. Wear safety glasses when handling with large magnets.

1. Sliding resistance

*Caution: On a vertical wall, the magnet retains only a fraction of its perpendicular strength.

2. Steel thickness impact

*Thin metal sheet (e.g. computer case) drastically limits the holding force.

3. Temperature resistance

*For N38 material, the max working temp is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.35

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 Pc (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 Pc 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.

Model MPL 25x12.5x5 / N38 features a flat shape and professional pulling force, making it an ideal solution for building separators and machines. As a block magnet with high power (approx. 7.72 kg), this product is available immediately from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.
The key to success is sliding 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. To separate the MPL 25x12.5x5 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.
They constitute a key element in the production of 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. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. 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 25x12.5x5 / N38 model is magnetized axially (dimension 5 mm), which means that the N and S poles are located on its largest, flat surfaces. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. 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: 25 mm (length), 12.5 mm (width), and 5 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 7.72 kg (force ~75.74 N), which, with such a flat shape, proves the high power of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of rare earth magnets.

Strengths

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • They retain magnetic properties for around 10 years – the drop is just ~1% (according to analyses),
  • They feature excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
  • The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to look better,
  • Magnetic induction on the top side of the magnet turns out to be exceptional,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
  • Possibility of custom forming as well as optimizing to atypical conditions,
  • Significant place in electronics industry – they find application in HDD drives, electric motors, medical equipment, as well as modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in compact constructions

Disadvantages

What to avoid - cons of neodymium magnets: application proposals
  • At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and 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 force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
  • They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in producing nuts and complicated forms in magnets, we recommend using a housing - magnetic holder.
  • Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these products are able to disrupt the diagnostic process medical in case of swallowing.
  • Due to neodymium price, their price is higher than average,

Holding force characteristics

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

The declared magnet strength refers to the peak performance, recorded under optimal environment, namely:
  • with the application of a sheet made of low-carbon steel, ensuring full magnetic saturation
  • whose transverse dimension is min. 10 mm
  • with a surface free of scratches
  • under conditions of gap-free contact (metal-to-metal)
  • for force acting at a right angle (pull-off, not shear)
  • at ambient temperature approx. 20 degrees Celsius

What influences lifting capacity in practice

Holding efficiency is influenced by specific conditions, such as (from priority):
  • Air gap (between the magnet and the plate), because even a tiny clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, rust or dirt).
  • Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
  • Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
  • Metal type – different alloys attracts identically. Alloy additives weaken the attraction effect.
  • Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
  • Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Safe handling of neodymium magnets
Avoid contact if allergic

Some people experience a hypersensitivity to Ni, which is the common plating for neodymium magnets. Prolonged contact might lead to an allergic reaction. We strongly advise wear safety gloves.

Crushing force

Big blocks can break fingers instantly. Never place your hand betwixt two strong magnets.

Fire risk

Dust produced during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Precision electronics

An intense magnetic field disrupts the operation of compasses in phones and GPS navigation. Keep magnets close to a device to avoid breaking the sensors.

Immense force

Handle magnets consciously. Their powerful strength can surprise even professionals. Stay alert and do not underestimate their force.

Permanent damage

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

Safe distance

Equipment safety: Strong magnets can damage data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).

No play value

Adult use only. Tiny parts can be swallowed, leading to serious injuries. Store away from kids and pets.

Fragile material

Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Health Danger

Warning for patients: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or request help to handle the magnets.
