Grip strength drops drastically per each millimeter of distance. Remember that even a microscopic distance (e.g., dirt, varnish, veneer) significantly diminishes the holding power. Magnetic products operate strongest during direct contact; gap weakens the power. Notice how rapidly the load capacity drop, when the product does not adhere directly to the metal substrate. When calculating the mounting, eliminate additional spacers.

This section indicates the approximate shear load required to initiate the slippage of the magnet downwards along a vertical metal surface (assuming typical friction). This value varies with the distance between the magnet and the surface.

When mounting a holder on a vertical wall (e.g., a board), it will only hold barely about 1/5 of its maximum pull force. Gravity as well as a weak degree of grip influence the fact that magnets move down easier than they pull off. Want to create a hanger? Note that the shear force is significantly lower than the perpendicular breakaway force. On a painted metal, the element will give way down under a much lighter weight. Application of an anti-slip layer can significantly increase the grip.

A thin sheet cannot absorb the full magnetic flux, which wastes potential of the magnet. If you install a neodymium to a weak sheet, the magnetism will pass right through and the attraction force will be weaker. To squeeze the maximum of this neodymium's potential, you need a suitably thick element of metal. The saturation effect means that on sheet metal structures (e.g., car bodies), the product works worse. We recommend selecting the steel thickness according to the table below.

Classic neodymiums lose parameters above the temperature limit. Protect against heat – excessive heat can irreversibly demagnetize this magnet. With increasing heat, the magnet's capacity briefly lowers. Do not use this magnet in hot environments higher than its working range. Ignoring the limit will cause permanent loss of magnetic properties.

*Technical advisory: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (pancake types) may lose charge permanently under lower heat stress than long magnets. The danger warning in the table signals a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a much further distance than a magnet and sheet setup. The connection of two magnets creates a more powerful interaction and a larger range of performance. Planning to create a powerful holder? Apply two magnets instead of one magnet and a steel. Be careful that when attracting two neodymiums, the impact force is extreme. The repulsion force is slightly lower than the connection force, but still impressive.
*Flux density for N-N configuration drops to ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Attention: Estimates refer to shear force of a pair of identical neodymium magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field poses a real danger to electronics as well as medical implants. These NdFeB products produce a field that prevents correct functioning of digital equipment. Be aware: the invisible magnetic field acts through matter and plastic. Increased vigilance must be taken by people with cochlear implants and drug dispensers. The risk also applies to: mechanical watches, car keys, speakers, and displays. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Magnetic elements are delicate – a strong collision with metal causes immediate chipping. Watch the impact speed – a neodymium left loose turns into a projectile. Kinetic force can trigger coating fragments or injury to fingers. Hold the magnet firmly during installation so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear safety glasses when working with powerful specimens.

Rust risk: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

The magnetic field penetrates through water without any losses. However, remember the water resistance when pulling the rope quickly.

1. Vertical hold

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

2. Plate thickness effect

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

3. Power loss vs temp

*For N38 grade, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (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 P_c (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 P_c 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 40x10x4 mm and a weight of 12 g, guarantees the highest quality connection. This rectangular block with a force of 91.33 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.

Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. Watch your fingers! Magnets with a force of 9.31 kg can pinch very hard and cause hematomas. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

They constitute a key element in the production of generators and material handling systems. Thanks to the flat surface and high force (approx. 9.31 kg), they are ideal as closers 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.

For mounting flat magnets MPL 40x10x4 / N38, it is best to use two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. 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. 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: 40 mm (length), 10 mm (width), and 4 mm (thickness). It is a magnetic block with dimensions 40x10x4 mm and a self-weight of 12 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of rare earth magnets.

Pros

Besides their remarkable strength, neodymium magnets offer the following advantages:

They have constant strength, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
Magnets very well defend themselves against loss of magnetization caused by external fields,
By covering with a shiny layer of silver, the element presents an professional look,
Magnets are distinguished by extremely high magnetic induction on the active area,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures reaching 230°C and above...
Thanks to flexibility in forming and the capacity to adapt to unusual requirements,
Universal use in advanced technology sectors – they are utilized in HDD drives, electromotive mechanisms, precision medical tools, also modern systems.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Disadvantages

Problematic aspects of neodymium magnets: application proposals

Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their durability
When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
We suggest a housing - magnetic holder, due to difficulties in creating nuts inside the magnet and complex shapes.
Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these devices can be problematic in diagnostics medical in case of swallowing.
With budget limitations the cost of neodymium magnets is economically unviable,

Lifting parameters

Maximum magnetic pulling force – what contributes to it?

The declared magnet strength refers to the limit force, measured under optimal environment, namely:

using a plate made of low-carbon steel, acting as a magnetic yoke
whose thickness reaches at least 10 mm
characterized by smoothness
under conditions of ideal adhesion (surface-to-surface)
for force applied at a right angle (in the magnet axis)
at temperature approx. 20 degrees Celsius

Magnet lifting force in use – key factors

Please note that the magnet holding will differ subject to elements below, in order of importance:

Clearance – existence of foreign body (rust, dirt, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
Load vector – highest force is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Plate material – low-carbon steel gives the best results. Higher carbon content lower magnetic properties and lifting capacity.
Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
Thermal environment – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

Precautions when working with neodymium magnets

Flammability

Fire hazard: Neodymium dust is explosive. Avoid machining magnets without safety gear as this risks ignition.

Nickel coating and allergies

It is widely known that nickel (the usual finish) is a common allergen. For allergy sufferers, avoid direct skin contact or opt for coated magnets.

Keep away from electronics

Be aware: rare earth magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your phone, tablet, and GPS.

Product not for children

NdFeB magnets are not toys. Swallowing several magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and necessitates urgent medical intervention.

Respect the power

Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

ICD Warning

Life threat: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.

Data carriers

Data protection: Strong magnets can damage payment cards and delicate electronics (pacemakers, medical aids, timepieces).

Bodily injuries

Danger of trauma: The pulling power is so immense that it can cause hematomas, pinching, and even bone fractures. Use thick gloves.

Do not overheat magnets

Regular neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.

Magnet fragility

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
