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 decreases sharply per each millimeter of spacing. Remember that every additional insulation layer (e.g., dirt, varnish, veneer) significantly diminishes the holding power. Magnetic products hold strongest in perfect adhesion; gap drastically cuts the force. Analyze how rapidly the pull force fall, when the product does not touch directly to the metal substrate. When planning the assembly, discard additional spacers.

The following data calculates the estimated holding capacity required to start the slippage of the magnet down 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 placing a element on a vertical wall (e.g., a fridge), it will maintain just about 1/5 of its nominal power. Gravity and a weak degree of grip influence the fact that products move down faster than they detach. Designing a vertical fastening? Remember that the shear force is much weaker than the perpendicular breakaway force. On a smooth steel, the element will slip down under a noticeably lighter weight. Utilizing a rubberized pad can drastically raise the stability.

A thin metal plate is not enough to absorb the full magnetic flux, which weakens actual performance of the holder. If you install a neodymium to a thin surface, the magnetism will penetrate right through and the holding will be smaller. To utilize 100% of this magnet's power, you require a sufficiently solid piece of metal. The saturation phenomenon causes that on sheet metal structures (e.g., car bodies), the magnet holds weaker. We advise picking the steel cross-section based on the following data.

Standard neodymium magnets lose strength above the temperature limit. Watch out for overheating – high temperature can irreversibly demagnetize this product. With increasing heat, the neodymium's force briefly lowers. Avoid using this product near heat sources higher than its working range. Too high temperature will result in irreversible degradation of magnetic properties.
*Technical advisory: 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 than taller cylinders. Red status in the table points to permanent field degradation for this particular item.

Two magnets interact from a significantly greater distance than a magnet and steel setup. The setup of two magnets creates a more powerful interaction and a larger range of action. Designing a strong closure? Apply two magnets instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the collision energy is huge. The levitation is slightly lower than the connection force, but still impressive.
*The magnetic induction in repulsion mode drops to ~0 Gs at the geometric center between the magnets (resulting from vector opposition).
* Calculations show sliding force of a pair of matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

Magnetic elements are prone to chipping – a violent impact against metal can result in shattering. Control the attraction moment – a magnet released freely becomes dangerous. Striking energy can cause material chips or injury to fingers. Be sure to control the product during mounting so it doesn't hit with great force against the metal. A collision at high speed ends with a crack of the magnet. Use safety goggles when working with large magnets.

1. Wall mount (shear)

*Note: On a vertical wall, the magnet holds only a fraction of its max power.

2. Efficiency vs thickness

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

3. Temperature resistance

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

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

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

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.

This product is a very powerful plate magnet made of NdFeB material, which, with dimensions of 40x15x5 mm and a weight of 22.5 g, guarantees the highest quality connection. This magnetic block with a force of 111.37 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 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 40x15x5 / 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 40x15x5 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. They work great as fasteners under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.
For mounting flat magnets MPL 40x15x5 / N38, we recommend utilizing two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. 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 40x15x5 / 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. 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.
The presented product is a neodymium magnet with precisely defined parameters: 40 mm (length), 15 mm (width), and 5 mm (thickness). It is a magnetic block with dimensions 40x15x5 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

Besides their tremendous field intensity, neodymium magnets offer the following advantages:
  • They retain magnetic properties for nearly ten years – the drop is just ~1% (based on simulations),
  • They have excellent resistance to magnetism drop when exposed to external fields,
  • In other words, due to the shiny layer of silver, the element gains visual value,
  • Neodymium magnets create maximum magnetic induction on a small area, which ensures high operational effectiveness,
  • Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
  • Thanks to flexibility in shaping and the ability to modify to complex applications,
  • Versatile presence in electronics industry – they are utilized in data components, electric motors, advanced medical instruments, and technologically advanced constructions.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Characteristics of disadvantages of neodymium magnets: tips and applications.
  • To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
  • When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
  • We suggest a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated shapes.
  • Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, small components of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum magnetic pulling force – what contributes to it?

Holding force of 11.35 kg is a theoretical maximum value executed under specific, ideal conditions:
  • with the use of a sheet made of low-carbon steel, ensuring full magnetic saturation
  • possessing a thickness of minimum 10 mm to avoid saturation
  • characterized by even structure
  • under conditions of gap-free contact (surface-to-surface)
  • during pulling in a direction perpendicular to the mounting surface
  • in stable room temperature

Practical lifting capacity: influencing factors

Real force is affected by specific conditions, mainly (from most important):
  • Clearance – existence of any layer (paint, tape, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
  • Angle of force application – highest force is available only during perpendicular pulling. The shear force of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
  • Plate thickness – too thin plate causes magnetic saturation, causing part of the power to be escaped into the air.
  • Material type – the best choice is pure iron steel. Stainless steels may attract less.
  • Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
  • Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet’s surface and the plate reduces the holding force.

Safety rules for work with NdFeB magnets
Implant safety

Warning for patients: Powerful magnets affect electronics. Keep at least 30 cm distance or request help to work with the magnets.

Phone sensors

GPS units and smartphones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.

Eye protection

Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Maximum temperature

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

Nickel allergy

Studies show that nickel (the usual finish) is a potent allergen. If your skin reacts to metals, refrain from direct skin contact and opt for encased magnets.

Electronic devices

Very strong magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.

Respect the power

Handle with care. Neodymium magnets act from a distance and connect with huge force, often faster than you can react.

Product not for children

Neodymium magnets are not toys. Eating a few magnets can lead to them pinching intestinal walls, which poses a severe health hazard and necessitates urgent medical intervention.

Do not drill into magnets

Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.

Bodily injuries

Risk of injury: The attraction force is so immense that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
