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 gap. Remember that even a very thin break (e.g., dirt, paint, dust) strongly reduces the pull force. Magnets operate most effectively during direct contact; gap weakens the force. Analyze how quickly the parameters drop, when the magnet does not touch tightly to the metal substrate. When calculating the arrangement, avoid unnecessary gaps.

The following data defines the theoretical weight limit needed to initiate the shifting of the magnet down along a vertical steel wall (assuming typical friction). This parameter varies with the air gap between the magnet and the surface.

When hanging a element on a vertical surface (e.g., a fridge), it you can count on only about 20%-30% of its nominal power. Gravity as well as a weak degree of grip influence the fact that holders slip faster than they pop off the substrate. Planning a vertical fastening? Consider that the sliding force is significantly lower than the perpendicular breakaway force. On a smooth steel, the element will slide down under a much lighter load. Utilizing a rubberized coating can drastically raise the stability.

A thin sheet is unable to absorb the full magnetic flux, which wastes potential of the holder. If you install a neodymium to a thin surface, the flux will penetrate right through and the attraction force will be weaker. To squeeze 100% of this neodymium's power, you need a suitably thick backing of steel. The material oversaturation causes that on sheet metal structures (e.g., car bodies), the magnet works worse. We suggest choosing the steel thickness according to the table below.

Classic neodymiums irreversibly lose strength after exceeding the maximum temperature. Protect against heat – heat can permanently destroy this magnet. As the temperature rises, the neodymium's power temporarily decreases. Refrain from using this magnet near heat sources higher than its safe range. Exceeding the critical threshold will cause permanent loss of magnetism.
*Engineering note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (pancake types) are more susceptible to demagnetization under lower heat stress compared to rod magnets. Warning indicator 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. The setup of magnet-to-magnet produces a massive flux and a further horizon of performance. Want to build a strong closure? Apply two magnets instead of a neodymium and a steel. Remember that when connecting a pair of magnets, the impact force is extreme. The levitation is slightly lower than the connection force, but still significant.
*Field value for N-N configuration is approximately ~0 Gs in the exact middle of the gap (resulting from vector opposition).
Note: Calculations refer to friction force of a pair of identical magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field poses a serious hazard to electronics and medical implants. These neodymiums generate a flux that destroys function of sensitive medical devices. Notice: the invisible magnetic field passes through tissues and plastic. Special caution must be exercised by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, car keys, membranes, and screens. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Neodymium magnets are very brittle – a violent impact against metal risks their cracking. Control the attraction moment – a neodymium left loose becomes dangerous. Striking energy can cause material chips or injury to skin. Always hold the magnet during mounting so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when working with powerful specimens.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!
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. Wall mount (shear)

*Note: On a vertical wall, the magnet holds just approx. 20-30% of its perpendicular strength.

2. Plate thickness effect

*Thin steel (e.g. 0.5mm PC case) drastically weakens the holding force.

3. Thermal stability

*For N38 material, the safety limit is 80°C.

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.40

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.

This product is a very powerful plate magnet made of NdFeB material, which, with dimensions of 15x15x5 mm and a weight of 8.44 g, guarantees premium class connection. This rectangular block with a force of 57.62 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.
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 5.87 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 fasteners 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 15x15x5 / 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. This is the most popular configuration for block magnets used in separators and holders.
This model is characterized by dimensions 15x15x5 mm, which, at a weight of 8.44 g, makes it an element with high energy density. It is a magnetic block with dimensions 15x15x5 mm and a self-weight of 8.44 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Advantages and disadvantages of Nd2Fe14B magnets.

Strengths

Besides their durability, neodymium magnets are valued for these benefits:
  • They retain attractive force for around 10 years – the loss is just ~1% (according to analyses),
  • They retain their magnetic properties even under strong external field,
  • The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • Neodymium magnets create maximum magnetic induction on a small area, which increases force concentration,
  • Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
  • Thanks to versatility in constructing and the ability to adapt to complex applications,
  • Versatile presence in electronics industry – they serve a role in magnetic memories, drive modules, precision medical tools, and multitasking production systems.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Problematic aspects 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 improves its resistance to damage
  • We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
  • They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Limited ability of producing threads in the magnet and complicated shapes - preferred is a housing - mounting mechanism.
  • Health risk to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child health protection. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical when they are in the body.
  • With budget limitations the cost of neodymium magnets is economically unviable,

Lifting parameters

Maximum lifting force for a neodymium magnet – what affects it?

The specified lifting capacity refers to the limit force, measured under laboratory conditions, specifically:
  • using a base made of mild steel, functioning as a ideal flux conductor
  • whose thickness reaches at least 10 mm
  • characterized by smoothness
  • under conditions of no distance (metal-to-metal)
  • for force applied at a right angle (pull-off, not shear)
  • at conditions approx. 20°C

Practical lifting capacity: influencing factors

It is worth knowing that the application force may be lower influenced by the following factors, in order of importance:
  • Distance – the presence of foreign body (paint, dirt, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
  • Base massiveness – too thin steel causes magnetic saturation, causing part of the power to be wasted into the air.
  • Material composition – different alloys attracts identically. Alloy additives worsen the attraction effect.
  • Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
  • Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.

Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.

Precautions when working with NdFeB magnets
Serious injuries

Risk of injury: The attraction force is so immense that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.

ICD Warning

People with a ICD must keep an safe separation from magnets. The magnetism can stop the operation of the implant.

Cards and drives

Intense magnetic fields can destroy records on credit cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.

Shattering risk

Beware of splinters. Magnets can explode upon violent connection, launching sharp fragments into the air. We recommend safety glasses.

Safe operation

Use magnets with awareness. Their powerful strength can surprise even experienced users. Plan your moves and do not underestimate their power.

Operating temperature

Avoid heat. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).

Mechanical processing

Powder generated during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.

Compass and GPS

Note: rare earth magnets generate a field that confuses precision electronics. Maintain a safe distance from your phone, tablet, and navigation systems.

Nickel allergy

A percentage of the population experience a contact allergy to Ni, which is the common plating for neodymium magnets. Prolonged contact can result in dermatitis. We suggest use safety gloves.

No play value

These products are not suitable for play. Eating several magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and necessitates urgent medical intervention.
