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.

Magnetic force weakens significantly with every mm of gap. Keep in mind that even the smallest gap (e.g., contamination, paint, rust) significantly diminishes the holding power. Neodymiums operate most effectively at the point of direct contact; gap drastically cuts the power. Notice how flashily the parameters drop, when the product does not adhere flatly to the metal substrate. When designing the arrangement, avoid additional spacers.

When placing a holder on a upright surface (e.g., a car body), it will maintain just approx. 1/5 of its maximum pull force. Gravitational force as well as a weak degree of grip influence the fact that holders slide down easier than they detach. Designing a wall mount? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will slip down under a noticeably lighter load. Application of an anti-slip pad can effectively improve the result.

A thin sheet is incapable of take in the full magnetic flux, which weakens actual performance of the magnet. Should you mount a strong magnet to a weak sheet, the field will penetrate right through and the pull force will drop sharply. To utilize full efficiency of this magnet's potential, you need a suitably thick element of metal. The material oversaturation means that on thin elements (e.g., appliance housings), the product works worse. We advise picking the steel dimension based on the following data.

Standard neodymium magnets change their properties parameters after exceeding the maximum temperature. Watch out for overheating – heat can permanently destroy this product. With increasing heat, the magnet's power temporarily decreases. Avoid using this product close to ovens higher than its working range. Ignoring the limit will lead to irreversible degradation of magnetism.
*Technical advisory: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low permeance coefficient) risk losing magnetic properties sooner than taller cylinders. Red status in the table points to permanent field degradation for this particular item.

Two magnets attract each other from a much further distance than a neodymium and metal setup. The setup of two magnets generates a stronger field and a further horizon of operation. Planning to create a solid fastener? Apply two magnets instead of one magnet and a steel. Remember that when bringing together two magnets, the impact force is extreme. The repulsion force is slightly lower than the attraction, but still significant.
*Field value for N-N configuration drops to ~0 Gs at the geometric center of the gap (due to field cancellation).
* Calculations show sliding force of a pair of same neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Extremely neodym field poses a real danger to electronics and pacemakers. These neodymiums produce a flux that disrupts operation of sensitive medical devices. Notice: the unseen radiation passes through tissues and plastic. Special caution must be taken by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, remotes, membranes, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Magnetic elements are delicate – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a magnet released freely speeds with massive force. Kinetic force can cause material chips or dangerous crushing to skin. Hold the magnet firmly during mounting so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the neodymium. Wear eye protection when handling with powerful specimens.

1. Shear force

*Warning: On a vertical surface, the magnet retains merely a fraction of its nominal pull.

2. Steel thickness impact

*Thin steel (e.g. 0.5mm PC case) significantly reduces 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) = 0.25

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 35x7x3 / N38 features a low profile and industrial pulling force, making it an ideal solution for building separators and machines. This rectangular block with a force of 60.89 N is ready for shipment in 24h, allowing for rapid realization of your project. Furthermore, its Ni-Cu-Ni coating protects it against corrosion in standard operating conditions, giving it an aesthetic appearance.
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 35x7x3 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend care, 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.
Plate magnets MPL 35x7x3 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 6.21 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. Customers often choose this model for hanging tools 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. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Remember to roughen and wash 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: 35 mm (length), 7 mm (width), and 3 mm (thickness). It is a magnetic block with dimensions 35x7x3 mm and a self-weight of 5.51 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths and weaknesses of neodymium magnets.

Benefits

Apart from their consistent magnetism, neodymium magnets have these key benefits:
  • Their magnetic field remains stable, and after around 10 years it drops only by ~1% (according to research),
  • Magnets perfectly protect themselves against loss of magnetization caused by external fields,
  • Thanks to the metallic finish, the layer of Ni-Cu-Ni, gold, or silver gives an elegant appearance,
  • Magnets have extremely high magnetic induction on the outer side,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Possibility of custom shaping as well as optimizing to individual needs,
  • Huge importance in modern industrial fields – they are utilized in magnetic memories, electromotive mechanisms, diagnostic systems, as well as multitasking production systems.
  • Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Disadvantages

Disadvantages of NdFeB magnets:
  • To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
  • Neodymium magnets lose their strength 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
  • When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
  • Due to limitations in realizing nuts and complex forms in magnets, we recommend using casing - magnetic mechanism.
  • Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these devices can complicate diagnosis medical in case of swallowing.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

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

The load parameter shown represents the maximum value, obtained under optimal environment, namely:
  • using a plate made of high-permeability steel, acting as a magnetic yoke
  • with a cross-section of at least 10 mm
  • characterized by lack of roughness
  • without any air gap between the magnet and steel
  • for force applied at a right angle (pull-off, not shear)
  • at conditions approx. 20°C

Key elements affecting lifting force

Effective lifting capacity is influenced by working environment parameters, including (from priority):
  • Clearance – existence of any layer (rust, tape, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
  • Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
  • Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
  • Metal type – different alloys reacts the same. High carbon content worsen the attraction effect.
  • Smoothness – full contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
  • Temperature – temperature increase results in weakening of force. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.

Safety rules for work with neodymium magnets
Metal Allergy

Studies show that the nickel plating (the usual finish) is a common allergen. If you have an allergy, prevent direct skin contact and choose encased magnets.

Thermal limits

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its properties and pulling force.

Fragile material

Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Caution required

Before use, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.

Impact on smartphones

Remember: rare earth magnets produce a field that disrupts precision electronics. Keep a separation from your phone, device, and GPS.

Combustion hazard

Drilling and cutting of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Bodily injuries

Big blocks can crush fingers in a fraction of a second. Do not place your hand between two attracting surfaces.

Swallowing risk

Only for adults. Tiny parts can be swallowed, leading to serious injuries. Keep away from kids and pets.

Threat to electronics

Avoid bringing magnets near a wallet, computer, or TV. The magnetism can destroy these devices and erase data from cards.

Health Danger

Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
