Pulling power drops drastically per each millimeter of spacing. Note that even the smallest gap (e.g., dirt, varnish, rust) strongly reduces the pull force. Neodymiums work strongest in perfect adhesion; gap nullifies the power. Observe how flashily the pull force fall, when the magnet does not touch tightly to the steel surface. When planning the assembly, eliminate unnecessary gaps.

The following data presents the approximate weight limit necessary to cause the sliding of the magnet down along a vertical metal surface (assuming standard friction). The holding force is a function of the gap size between the magnet and the metal.

When hanging a magnet on a vertical surface (e.g., a fridge), it will only hold barely approx. 20%-30% of nominal attraction strength. Gravitational force and a weak degree of grip influence the fact that magnets slip faster than they detach. Want to create a hanger? Note that the sliding force is much weaker than the maximum static pull force. On a painted metal, the element will slide down under a noticeably lighter load. Application of an anti-slip coating can significantly improve the result.

A thin sheet is not enough to focus the entire magnetic field, which weakens actual performance of the magnet. Should you install a neodymium to a weak sheet, the field will pass right through and the holding will be smaller. To utilize full efficiency of this neodymium's power, you require a sufficiently solid element of metal. The saturation effect means that on thin elements (e.g., thin profiles), the holder holds weaker. We suggest choosing the steel cross-section according to the table below.

Standard neodymium magnets change their properties power above the temperature limit. Avoid high temperatures – high temperature can irreversibly destroy this product. With every degree above norm, the neodymium's capacity briefly decreases. Refrain from using this magnet close to ovens higher than its safe range. Ignoring the limit will lead to irreversible degradation of magnetic properties.
*Technical advisory: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (low Pc) risk losing magnetic properties sooner compared to rod magnets. The danger warning in the table indicates a risk of irreversible loss for this particular item.

Two magnets interact from a wider radius than a magnet and sheet setup. The connection of magnet-to-magnet creates a more powerful interaction and a larger range of action. Designing a strong closure? Use a pair of magnets instead of one magnet and a steel. Remember that when attracting two neodymiums, the impact force is extreme. The levitation is slightly lower than the attraction, but still large.
*Field value between like poles reaches ~0 Gs at the midpoint of the gap (resulting from vector opposition).
Note: Results apply to sliding force of two matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni plating).

A strong magnetic field poses a real danger to electronic devices as well as pacemakers. These magnets produce a flux that disrupts operation of digital equipment. Be aware: the invisible magnetic field penetrates the body and glass. Exceptional care must be taken by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, remotes, speakers, and screens. Do not place the magnet near cards, hard drives, or precise measuring instruments.

NdFeB products are delicate – a violent impact against metal can result in shattering. Watch the impact speed – a neodymium left loose becomes dangerous. Striking energy can cause material chips or injury to fingers. Always hold the magnet during installation so it doesn't hit violently against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Wear safety glasses when working with powerful specimens.

1. Sliding resistance

*Warning: On a vertical wall, the magnet retains only approx. 20-30% of its nominal pull.

2. Efficiency vs thickness

*Thin steel (e.g. computer case) significantly limits the holding force.

3. Power loss vs temp

*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

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 30x20x5 / N38 features a low profile and industrial pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 8.86 kg), this product is available immediately from our warehouse in Poland. 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. To separate the MPL 30x20x5 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, 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 30x20x5 / 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. 8.86 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 30x20x5 / 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).
The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. In practice, this means that this magnet has the greatest attraction force on its main planes (30x20 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: 30 mm (length), 20 mm (width), and 5 mm (thickness). The key parameter here is the holding force amounting to approximately 8.86 kg (force ~86.90 N), which, with such a compact shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Advantages as well as disadvantages of Nd2Fe14B magnets.

Advantages

Apart from their notable holding force, neodymium magnets have these key benefits:
  • They retain full power for nearly ten years – the loss is just ~1% (according to analyses),
  • Magnets perfectly resist against loss of magnetization caused by ambient magnetic noise,
  • The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to present itself better,
  • They feature high magnetic induction at the operating surface, which affects their effectiveness,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
  • Possibility of exact forming and adjusting to defined conditions,
  • Versatile presence in modern technologies – they are utilized in data components, electric drive systems, precision medical tools, also modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in small systems

Weaknesses

Disadvantages of NdFeB magnets:
  • Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also increases their durability
  • Neodymium magnets decrease their power 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 durability even at temperatures up to 230°C
  • They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in realizing nuts and complex shapes in magnets, we recommend using casing - magnetic mount.
  • Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small elements of these devices can disrupt the diagnostic process medical after entering the body.
  • Due to complex production process, their price is relatively high,

Holding force characteristics

Magnetic strength at its maximum – what contributes to it?

Magnet power is the result of a measurement for the most favorable conditions, including:
  • with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
  • whose thickness reaches at least 10 mm
  • with a plane cleaned and smooth
  • under conditions of ideal adhesion (surface-to-surface)
  • for force applied at a right angle (pull-off, not shear)
  • at temperature room level

Lifting capacity in practice – influencing factors

Bear in mind that the magnet holding may be lower depending on the following factors, in order of importance:
  • Clearance – the presence of any layer (paint, tape, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
  • Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of maximum force).
  • Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
  • Steel type – mild steel attracts best. Higher carbon content reduce magnetic properties and lifting capacity.
  • Surface finish – full contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
  • Thermal environment – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet’s surface and the plate lowers the holding force.

Warnings
Handling rules

Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.

Hand protection

Pinching hazard: The attraction force is so great that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.

Medical implants

Warning for patients: Powerful magnets affect medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.

Do not drill into magnets

Powder produced during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Adults only
