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 drops sharply with every mm of spacing. Remember that even a very thin break (e.g., contamination, varnish, dust) strongly reduces the pull force. Magnetic products operate most effectively in perfect adhesion; distance kills the force. Analyze how quickly the pull force fall, when the product does not touch directly to the steel surface. When planning the arrangement, eliminate additional spacers.

This section presents the estimated weight limit necessary to start the sliding of the magnet vertically along a upright steel plate (assuming standard friction coefficient). The holding force is a function of the separation distance between the magnet and the surface.

When placing a magnet on a upright plane (e.g., a fridge), it will maintain only about 1/5 of its maximum pull force. Gravity and a low friction coefficient influence the fact that holders slip faster than they pop off the substrate. Planning a vertical fastening? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will slide down under a much lighter cargo. Using a rubber layer can significantly improve the result.

A too thin steel is incapable of absorb the entire magnetic field, which wastes potential of the holder. If you attach a powerful product to a too thin substrate, the flux will pass right through and the attraction force will be weaker. To squeeze full efficiency of this magnet's potential, you require a sufficiently solid piece of metal. The saturation effect means that on sheet metal structures (e.g., appliance housings), the holder works worse. We advise picking the steel cross-section according to the table below.

Classic neodymiums lose strength above the temperature limit. Protect against heat – heat can permanently damage this product. With increasing heat, the neodymium's capacity briefly decreases. Avoid using this product close to ovens higher than its safe range. Exceeding the critical threshold will result in destruction of magnetism.
*Technical advisory: Thermal stability is determined by both grade, but also on the magnet's shape. Flat magnets (low Pc) may lose charge permanently sooner than long magnets. Red status in the table points to permanent field degradation for this specific geometry.

Two magnets interact from a significantly greater distance than a neodymium and metal combination. Such a system of two magnets produces a massive flux and a larger range of performance. Designing a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the pinch force is extreme. The levitation is a bit weaker than the connection force, but still impressive.
*The magnetic induction in repulsion mode reaches ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Note: Estimates show sliding force of dual identical neodymium magnets (friction ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a large risk to electronics and medical implants. These magnets generate a field that prevents correct functioning of digital equipment. Remember: the invisible magnetic field passes through tissues and glass. Special caution must be taken by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, car keys, speakers, and screens. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Magnetic elements are delicate – a strong collision with metal risks their cracking. Watch the impact speed – a magnet released freely turns into a projectile. Striking energy can trigger coating fragments or injury to skin. Be sure to control the product during mounting so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the magnet. Wear safety glasses when handling with powerful specimens.

Warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.
In water, the magnet feels stronger thanks to Archimedes' principle. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Sliding resistance

*Note: On a vertical wall, the magnet holds merely approx. 20-30% of its nominal pull.

2. Efficiency vs thickness

*Thin steel (e.g. 0.5mm PC case) significantly limits the holding force.

3. Power loss vs temp

*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) = 0.43

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 40x40x15 / N38 features a flat shape and professional pulling force, making it a perfect solution for building separators and machines. This rectangular block with a force of 460.51 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 46.94 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. Thanks to the flat surface and high force (approx. 46.94 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.
For mounting flat magnets MPL 40x40x15 / 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.
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. 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: 40 mm (length), 40 mm (width), and 15 mm (thickness). It is a magnetic block with dimensions 40x40x15 mm and a self-weight of 180 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Advantages and disadvantages of rare earth magnets.

Benefits

Besides their high retention, neodymium magnets are valued for these benefits:
  • They do not lose power, even over around ten years – the reduction in power is only ~1% (according to tests),
  • Neodymium magnets are characterized by extremely resistant to loss of magnetic properties caused by external magnetic fields,
  • The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
  • Neodymium magnets create maximum magnetic induction on a small surface, which increases force concentration,
  • 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 custom creating as well as modifying to atypical applications,
  • Huge importance in modern technologies – they are commonly used in computer drives, electric motors, diagnostic systems, also multitasking production systems.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
  • We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
  • Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
  • We suggest cover - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated forms.
  • Health risk to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Furthermore, small components of these magnets can be problematic in diagnostics medical in case of swallowing.
  • Due to expensive raw materials, their price is relatively high,

Holding force characteristics

Magnetic strength at its maximum – what contributes to it?

The lifting capacity listed is a theoretical maximum value executed under the following configuration:
  • on a block made of structural steel, effectively closing the magnetic field
  • whose transverse dimension reaches at least 10 mm
  • with a plane cleaned and smooth
  • without the slightest air gap between the magnet and steel
  • under vertical force vector (90-degree angle)
  • at standard ambient temperature

Determinants of lifting force in real conditions

During everyday use, the real power results from a number of factors, ranked from the most important:
  • Air gap (betwixt the magnet and the plate), because even a microscopic distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
  • Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
  • Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
  • Metal type – different alloys reacts the same. Alloy additives weaken the attraction effect.
  • Surface condition – ground elements ensure maximum contact, which improves force. Uneven metal reduce efficiency.
  • Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet and the plate decreases the load capacity.

Precautions when working with neodymium magnets
Mechanical processing

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

Magnet fragility

Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.

Skin irritation risks

Medical facts indicate that nickel (the usual finish) is a potent allergen. For allergy sufferers, prevent direct skin contact or opt for coated magnets.

Choking Hazard

Only for adults. Tiny parts can be swallowed, causing severe trauma. Keep away from kids and pets.

Pinching danger

Pinching hazard: The attraction force is so immense that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.

Warning for heart patients

For implant holders: Powerful magnets affect electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.

Thermal limits

Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. Damage is permanent.

Keep away from computers

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

Handling rules

Use magnets with awareness. Their powerful strength can shock even professionals. Stay alert and do not underestimate their force.

Precision electronics

Remember: neodymium magnets produce a field that disrupts precision electronics. Keep a separation from your mobile, device, and navigation systems.
