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 drops sharply with every subsequent millimeter of spacing. Note that every additional insulation layer (e.g., contamination, paint, rust) noticeably weakens the grip. Magnetic products hold strongest in perfect adhesion; gap drastically cuts the power. Observe how quickly the pull force drop, when the magnet does not touch directly to the metal substrate. When planning the assembly, eliminate unnecessary gaps.

The following data calculates the approximate force sufficient to cause the slippage of the magnet downwards along a vertical steel wall (assuming typical friction). The holding force is a function of the distance between the magnet and the surface.

When placing a holder on a vertical plane (e.g., a car body), it will only hold just 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. Planning a vertical fastening? Remember that the shear force is much weaker than the maximum static pull force. On a painted metal, the holder will give way down under a noticeably lighter cargo. Utilizing a rubberized coating can effectively raise the stability.

A too thin steel cannot conduct the full magnetic flux, which squanders power of the holder. If you install a neodymium to a weak sheet, the field will penetrate right through and the attraction force will be weaker. To achieve the maximum of this neodymium's potential, you require a sufficiently solid backing of steel. The saturation effect causes that on delicate walls (e.g., appliance housings), the holder holds weaker. We recommend selecting the steel thickness according to the table below.

Classic neodymiums change their properties power after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly demagnetize this magnet. As the temperature rises, the neodymium's force momentarily lowers. Avoid using this magnet in hot environments exceeding its working range. Too high temperature will result in irreversible degradation of magnetic properties.
*Technical advisory: Thermal stability depends not only on the material grade, but also on the magnet's shape. Flat magnets (pancake types) risk losing magnetic properties under lower heat stress compared to rod magnets. Warning indicator in the table points to a risk of irreversible loss for this particular item.

Two magnets attract each other from a significantly greater distance than a magnet and steel setup. The connection of magnet-to-magnet creates a more powerful interaction and a further horizon of action. Want to build a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Remember that when bringing together two magnets, the pinch force is huge. The levitation is marginally weaker than the attraction, but still significant.
*Flux density between like poles is approximately ~0 Gs at the midpoint of the gap (due to field cancellation).
Important: Figures apply to sliding force of two same magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field poses a serious hazard to IT equipment and medical implants. These magnets produce a field that prevents correct functioning of digital equipment. Notice: the unseen radiation acts through matter and glass. Exceptional care must be taken by people with hearing aids and drug dispensers. Influence will be felt by: mechanical watches, remotes, membranes, and displays. Avoid contact with magnetic cards, hard drives, or precise measuring instruments.

Neodymium magnets are prone to chipping – a strong collision with metal risks their cracking. Control the attraction moment – a magnet released freely speeds with massive force. Striking energy can cause material chips or dangerous crushing to skin. Hold the magnet firmly during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h almost guarantees destruction of the neodymium. Wear eye protection when working with large magnets.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!
In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

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

2. Efficiency vs thickness

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient Pc (Permeance Coefficient) = 0.26

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 60x10x5 mm and a weight of 22.5 g, guarantees the highest quality connection. This rectangular block with a force of 178.10 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 60x10x5 / 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. Using a screwdriver risks destroying the coating and permanently cracking the magnet.
Plate magnets MPL 60x10x5 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 18.16 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. 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. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).
Standardly, the MPL 60x10x5 / N38 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 (60x10 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: 60 mm (length), 10 mm (width), and 5 mm (thickness). It is a magnetic block with dimensions 60x10x5 mm and a self-weight of 22.5 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths as well as weaknesses of Nd2Fe14B magnets.

Pros

In addition to their long-term stability, neodymium magnets provide the following advantages:
  • They have stable power, and over around ten years their performance decreases symbolically – ~1% (according to theory),
  • They are noted for resistance to demagnetization induced by external disturbances,
  • By using a reflective coating of silver, the element has an modern look,
  • Magnetic induction on the working part of the magnet turns out to be strong,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Thanks to flexibility in designing and the ability to adapt to client solutions,
  • Wide application in modern technologies – they are used in data components, drive modules, precision medical tools, as well as modern systems.
  • Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Disadvantages

Disadvantages of neodymium magnets:
  • To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
  • When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
  • We suggest casing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated shapes.
  • Health risk resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these products can complicate diagnosis medical after entering the body.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum lifting capacity of the magnet – what it depends on?

The specified lifting capacity concerns the peak performance, recorded under laboratory conditions, specifically:
  • on a base made of structural steel, effectively closing the magnetic flux
  • possessing a thickness of at least 10 mm to avoid saturation
  • with a plane cleaned and smooth
  • with zero gap (no coatings)
  • during detachment in a direction perpendicular to the mounting surface
  • in temp. approx. 20°C

Lifting capacity in practice – influencing factors

In real-world applications, the actual holding force results from several key aspects, listed from the most important:
  • Clearance – the presence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
  • Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
  • Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
  • Material type – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
  • Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
  • Thermal environment – heating the magnet results in weakening of force. Check the thermal limit for a given model.

Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.

Safety rules for work with NdFeB magnets
Do not drill into magnets

Fire hazard: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.

Health Danger

Patients with a heart stimulator should keep an safe separation from magnets. The magnetism can interfere with the operation of the implant.

Adults only

Always keep magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are fatal.

Cards and drives

Do not bring magnets near a purse, computer, or screen. The magnetic field can permanently damage these devices and wipe information from cards.

Compass and GPS

A strong magnetic field interferes with the functioning of compasses in phones and navigation systems. Keep magnets near a smartphone to prevent damaging the sensors.

Heat sensitivity

Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. This process is irreversible.

Powerful field

Use magnets with awareness. Their immense force can shock even experienced users. Be vigilant and do not underestimate their force.

Bodily injuries

Protect your hands. Two large magnets will join immediately with a force of massive weight, destroying everything in their path. Exercise extreme caution!

Beware of splinters

Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.

Avoid contact if allergic

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness occurs, cease working with magnets and use protective gear.
