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 mm of spacing. Remember that even a microscopic distance (e.g., dirt, paint, rust) noticeably reduces the pull force. Magnetic products work most effectively during direct contact; gap kills the force. Observe how rapidly the load capacity plummet, when the magnet does not touch tightly to the metal substrate. When planning the assembly, avoid redundant distances.

This section calculates the theoretical holding capacity required to cause the sliding of the magnet vertically on a vertical steel wall (assuming typical friction coefficient). The holding force is a function of the separation distance between the magnet and the surface.

When hanging a magnet on a vertical surface (e.g., a car body), it you can count on only about 1/5 of nominal attraction strength. Gravity as well as a weak degree of grip mean that magnets slide down faster than they detach. Designing a vertical fastening? Consider that the sliding force is significantly lower than the maximum static pull force. On a smooth steel, the holder will slip down under a much lighter weight. Utilizing a rubberized coating can effectively raise the stability.

A thin sheet cannot focus the full magnetic flux, which squanders power of the holder. If you install a neodymium to a weak sheet, the flux will pass right through and the pull force will drop sharply. To achieve 100% of this magnet's power, you require a sufficiently solid backing of steel. The saturation effect causes that on thin elements (e.g., car bodies), the holder works worse. We advise picking the steel cross-section from these parameters.

Standard neodymium magnets change their properties parameters above the temperature limit. Watch out for overheating – excessive heat can permanently destroy this magnet. As the temperature rises, the neodymium's capacity temporarily drops. Do not use this magnet close to ovens exceeding its safe range. Exceeding the critical threshold will result in destruction of magnetic properties.
*Engineering note: Heat tolerance is determined by both grade, but also on the magnet's shape. Flat magnets (pancake types) risk losing magnetic properties at lower temperatures compared to rod magnets. Warning indicator in the table signals a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a wider radius than a magnet and sheet combination. The connection of two magnets creates a more powerful interaction and a further horizon of operation. Designing a strong closure? Apply two magnets instead of a neodymium and a steel. Be careful that when attracting two neodymiums, the collision energy is huge. The levitation is a bit weaker than the attraction, but still impressive.
*The magnetic induction for N-N configuration is approximately ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
* Estimates show sliding force of a pair of same neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field is a real danger to electronics as well as medical implants. These NdFeB products generate a field that destroys function of sensitive medical devices. Notice: the invisible magnetic field acts through matter and glass. Exceptional care must be taken by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, car keys, membranes, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Neodymium magnets are delicate – a collision with steel risks their cracking. Pay attention to connection velocity – a magnet released freely speeds with massive force. Impact energy can cause material chips or dangerous crushing to fingers. Always hold the magnet during installation so it doesn't hit violently against the metal. A collision at high speed means shattering of the neodymium. Wear eye protection when working with large magnets.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!
Water displaces steel, making heavy objects slightly lighter. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Shear force

*Note: On a vertical wall, the magnet holds merely ~20% of its nominal pull.

2. Steel thickness impact

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.38

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 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.

Component MPL 25x10x5 / N38 features a flat shape and professional pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 7.49 kg), this product is available immediately from our warehouse in Poland. Additionally, 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 7.49 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.
Plate magnets MPL 25x10x5 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. 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.
For mounting flat magnets MPL 25x10x5 / N38, it is best to use two-component adhesives (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 clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.
Standardly, the MPL 25x10x5 / N38 model is magnetized axially (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 (25x10 mm), which is ideal for flat mounting. 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: 25 mm (length), 10 mm (width), and 5 mm (thickness). It is a magnetic block with dimensions 25x10x5 mm and a self-weight of 9.38 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Pros and cons of neodymium magnets.

Pros

In addition to their long-term stability, neodymium magnets provide the following advantages:
  • They have constant strength, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
  • They possess excellent resistance to weakening of magnetic properties as a result of opposing magnetic fields,
  • A magnet with a smooth gold surface looks better,
  • Magnets are distinguished by exceptionally strong magnetic induction on the active area,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • Possibility of individual machining and optimizing to specific applications,
  • Fundamental importance in electronics industry – they are utilized in computer drives, drive modules, medical equipment, and modern systems.
  • Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Cons

Drawbacks and weaknesses of neodymium magnets and ways of using them
  • They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
  • Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
  • We suggest a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated shapes.
  • Potential hazard to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child health protection. Furthermore, small elements of these devices are able to complicate diagnosis medical when they are in the body.
  • With budget limitations the cost of neodymium magnets can be a barrier,

Lifting parameters

Highest magnetic holding force – what contributes to it?

The load parameter shown concerns the peak performance, measured under ideal test conditions, namely:
  • on a base made of structural steel, optimally conducting the magnetic field
  • with a thickness no less than 10 mm
  • characterized by smoothness
  • with zero gap (no impurities)
  • during detachment in a direction vertical to the plane
  • at temperature approx. 20 degrees Celsius

Magnet lifting force in use – key factors

Effective lifting capacity is influenced by working environment parameters, such as (from most important):
  • Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
  • Direction of force – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
  • Metal type – different alloys reacts the same. High carbon content weaken the attraction effect.
  • Surface condition – ground elements ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
  • Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.

H&S for magnets
Keep away from computers

Device Safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).

Heat warning

Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its properties and strength.

Keep away from electronics

An intense magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Maintain magnets close to a device to avoid breaking the sensors.

Bodily injuries

Large magnets can break fingers instantly. Do not place your hand betwixt two attracting surfaces.

Do not underestimate power

Be careful. Rare earth magnets act from a distance and snap with huge force, often quicker than you can react.

Life threat

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

Swallowing risk

Strictly store magnets away from children. Ingestion danger is high, and the consequences of magnets clamping inside the body are fatal.

Do not drill into magnets

Fire hazard: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.

Magnets are brittle

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Skin irritation risks

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, cease handling magnets and wear gloves.
