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.

Pulling power weakens significantly with every subsequent millimeter of distance. Remember that even a very thin break (e.g., contamination, varnish, rust) strongly reduces the pull force. Magnets operate optimally during direct contact; gap nullifies the power. Notice how flashily the load capacity fall, when the magnet does not touch directly to the metal substrate. When planning the assembly, discard unnecessary gaps.

The table below defines the approximate holding capacity sufficient to cause the sliding of the magnet vertically against a vertical steel plate (considering typical friction). The holding force is relative to the gap size between the magnet and the surface.

When mounting a element on a vertical wall (e.g., a board), it will only hold barely about 1/5 of its nominal power. Gravitational force and a weak degree of grip mean that holders slide down faster than they pop off the substrate. Want to create a hanger? Remember that the sliding force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the holder will slip down under a much lighter cargo. Utilizing a rubberized coating can drastically increase the grip.

A too thin steel is incapable of focus the full magnetic flux, which squanders power of the magnet. If you install a neodymium to a weak sheet, the field will penetrate right through and the pull force will drop sharply. To achieve full efficiency of this magnet's potential, you require a sufficiently solid element of steel. The saturation effect causes that on thin elements (e.g., thin profiles), the product works worse. We recommend selecting the steel cross-section according to the table below.

Ordinary NdFeB products lose strength past the thermal threshold. Avoid high temperatures – heat can permanently damage this magnet. With every degree above norm, the magnet's force temporarily drops. Do not use this magnet in hot environments exceeding its safe range. Exceeding the critical threshold will cause destruction of magnetism.
*Engineering note: Heat tolerance is determined by both grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) risk losing magnetic properties at lower temperatures compared to rod magnets. Red status in the table indicates permanent field degradation for this specific geometry.

Two strong neodymiums attract each other from a significantly greater distance than a neodymium and metal setup. Such a system of magnet-to-magnet creates a more powerful interaction and a further horizon of operation. Want to build a strong closure? Utilize two neodymiums instead of one magnet and a striker plate. Remember that when connecting a pair of magnets, the pinch force is huge. The repulsion force is slightly lower than the attraction, but still significant.
*Flux density between like poles drops to ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Note: Estimates demonstrate sliding force of two matching magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a real danger to IT equipment as well as pacemakers. These magnets produce a flux that destroys function of digital equipment. Remember: the unseen radiation penetrates the body and housings. Exceptional care must be taken by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

NdFeB products are prone to chipping – a strong collision with metal causes immediate chipping. Watch the impact speed – a neodymium left loose speeds with massive force. Striking energy can trigger coating fragments or injury to fingers. Hold the magnet firmly during installation so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h means shattering of the magnet. Use safety goggles when playing with powerful specimens.

Corrosion warning: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.
The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

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

2. Steel saturation

*Thin metal sheet (e.g. computer case) severely 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 Pc (Permeance Coefficient) = 0.49

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 13x10x5 / N35H features a flat shape and industrial pulling force, making it an ideal solution for building separators and machines. This magnetic block with a force of 39.54 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 4.03 kg can pinch very hard and cause hematomas. 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. Customers often choose this model for workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.
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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).
Standardly, the MPL 13x10x5 / N35H model is magnetized through the thickness (dimension 5 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 (13x10 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.
This model is characterized by dimensions 13x10x5 mm, which, at a weight of 4.88 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 13x10x5 mm and a self-weight of 4.88 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of rare earth magnets.

Benefits

Apart from their notable holding force, neodymium magnets have these key benefits:
  • They have stable power, and over around ten years their performance decreases symbolically – ~1% (according to theory),
  • Neodymium magnets remain exceptionally resistant to loss of magnetic properties caused by external interference,
  • A magnet with a metallic nickel surface has an effective appearance,
  • They feature high magnetic induction at the operating surface, which affects their effectiveness,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
  • Thanks to freedom in designing and the capacity to adapt to complex applications,
  • Key role in modern technologies – they are commonly used in magnetic memories, electric motors, precision medical tools, and other advanced devices.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Limitations

Disadvantages of neodymium magnets:
  • To avoid cracks under impact, we suggest using special steel holders. Such a solution protects 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 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
  • Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
  • Due to limitations in realizing threads and complex shapes in magnets, we recommend using cover - magnetic holder.
  • Health risk to health – tiny shards of magnets are risky, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that tiny parts of these products can complicate diagnosis medical in case of swallowing.
  • With mass production the cost of neodymium magnets is economically unviable,

Holding force characteristics

Maximum magnetic pulling force – what it depends on?

Information about lifting capacity is the result of a measurement for ideal contact conditions, including:
  • on a plate made of mild steel, effectively closing the magnetic field
  • possessing a massiveness of minimum 10 mm to ensure full flux closure
  • with an polished touching surface
  • under conditions of no distance (metal-to-metal)
  • under perpendicular force direction (90-degree angle)
  • at ambient temperature approx. 20 degrees Celsius

Lifting capacity in practice – influencing factors

Bear in mind that the application force will differ subject to the following factors, in order of importance:
  • Clearance – the presence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
  • Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
  • Plate thickness – insufficiently thick steel does not accept the full field, causing part of the flux to be escaped to the other side.
  • Chemical composition of the base – low-carbon steel attracts best. Higher carbon content decrease magnetic properties and holding force.
  • Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
  • Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, however under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet’s surface and the plate lowers the holding force.

Safety rules for work with neodymium magnets
Keep away from children

Adult use only. Tiny parts pose a choking risk, leading to severe trauma. Store away from kids and pets.

Health Danger

For implant holders: Powerful magnets affect medical devices. Keep at least 30 cm distance or request help to work with the magnets.

Flammability

Powder created during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Bodily injuries

Danger of trauma: The pulling power is so great that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.

Keep away from computers

Avoid bringing magnets close to a wallet, computer, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.

Respect the power

Use magnets consciously. Their powerful strength can surprise even professionals. Plan your moves and respect their power.

Demagnetization risk

Monitor thermal conditions. Exposing the magnet to high heat will destroy its properties and pulling force.

Warning for allergy sufferers

Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, immediately stop working with magnets and use protective gear.

Keep away from electronics

Note: rare earth magnets produce a field that confuses precision electronics. Keep a separation from your mobile, device, and GPS.

Protective goggles

Beware of splinters. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Wear goggles.
