Magnetic force decreases significantly per each millimeter of spacing. Note that even a microscopic distance (e.g., dirt, varnish, veneer) significantly diminishes the holding power. Magnets operate most effectively in perfect adhesion; distance kills the power. Analyze how flashily the pull force drop, when the magnet does not adhere flatly to the steel surface. When calculating the assembly, avoid unnecessary gaps.

The table below shows the theoretical holding capacity sufficient to start the slippage of the magnet down on a vertical steel plate (considering typical friction coefficient). This parameter is relative to the gap size between the magnet and the metal.

When placing a holder on a upright plane (e.g., a board), it will only hold only approx. 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip cause that magnets move down faster than they pop off the substrate. Designing a hanger? Consider that the shear force is much weaker than the perpendicular breakaway force. On a smooth steel, the magnet will slide down under a significantly smaller load. Using a rubber layer can significantly raise the stability.

A thin sheet cannot absorb the full magnetic flux, which squanders power of the holder. Should you install a neodymium to a thin surface, the magnetism will penetrate right through and the holding will be smaller. To achieve full efficiency of this magnet's potential, you require a sufficiently solid element of steel. The saturation effect causes that on delicate walls (e.g., car bodies), the product holds weaker. We recommend selecting the steel dimension according to the table below.

Standard neodymium magnets change their properties power after exceeding the maximum temperature. Watch out for overheating – high temperature can permanently demagnetize this product. With every degree above norm, the magnet's force briefly decreases. Avoid using this product near heat sources exceeding its working range. Exceeding the critical threshold will cause destruction of magnetism.

*Important note: Thermal stability depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) may lose charge permanently sooner than taller cylinders. The danger warning in the table indicates a risk of irreversible loss for this particular item.

Two strong neodymiums 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 larger range of operation. Want to build a solid fastener? Apply two magnets instead of one magnet and a striker plate. Be careful that when connecting a pair of magnets, the collision energy is massive. The repulsion force is marginally weaker than the connection force, but still significant.
*The magnetic induction for N-N configuration drops to ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Important: Results show sliding force of a pair of matching neodymium magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field poses a large risk to electronics and pacemakers. These NdFeB products generate a flux that prevents correct functioning of digital equipment. Remember: the invisible magnetic field acts through matter and housings. Exceptional care must be taken by people with cochlear implants and insulin pumps. Also at risk are: mechanical watches, car keys, membranes, and displays. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a collision with steel can result in shattering. Control the attraction moment – a neodymium left loose speeds with massive force. Kinetic force can destroy the magnet or dangerous crushing to fingers. 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. Use safety goggles when working with powerful specimens.

Corrosion 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. Vertical hold

*Note: On a vertical surface, the magnet holds merely ~20% of its nominal pull.

2. Plate thickness effect

*Thin steel (e.g. computer case) significantly 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) = 0.63

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 50x20x20 mm and a weight of 150 g, guarantees the highest quality connection. This magnetic block with a force of 413.81 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 strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 50x20x20 / 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.

They constitute a key element in the production of wind generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

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. In practice, this means that this magnet has the greatest attraction force on its main planes (50x20 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 50x20x20 mm, which, at a weight of 150 g, makes it an element with high energy density. The key parameter here is the lifting capacity amounting to approximately 42.18 kg (force ~413.81 N), which, with such a flat shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Strengths

Besides their durability, neodymium magnets are valued for these benefits:

They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (according to literature),
They are extremely resistant to demagnetization induced by external magnetic fields,
Thanks to the reflective finish, the layer of nickel, gold, or silver gives an elegant appearance,
The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
Possibility of precise machining as well as adapting to individual conditions,
Huge importance in advanced technology sectors – they are used in magnetic memories, electric drive systems, medical equipment, and other advanced devices.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
Due to limitations in producing threads and complicated forms in magnets, we recommend using a housing - magnetic holder.
Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Additionally, small elements of these products can disrupt the diagnostic process medical in case of swallowing.
With mass production the cost of neodymium magnets is economically unviable,

Holding force characteristics

Maximum lifting capacity of the magnet – what contributes to it?

The lifting capacity listed is a result of laboratory testing conducted under the following configuration:

with the use of a sheet made of special test steel, ensuring full magnetic saturation
whose transverse dimension reaches at least 10 mm
with a surface free of scratches
with total lack of distance (without paint)
for force acting at a right angle (in the magnet axis)
at room temperature

Impact of factors on magnetic holding capacity in practice

In real-world applications, the real power is determined by many variables, listed from crucial:

Clearance – the presence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
Steel type – low-carbon steel gives the best results. Higher carbon content decrease magnetic permeability and holding force.
Surface structure – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
Thermal factor – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.

H&S for magnets

Bone fractures

Big blocks can break fingers in a fraction of a second. Do not put your hand betwixt two attracting surfaces.

Risk of cracking

Neodymium magnets are sintered ceramics, which means they are fragile like glass. Collision of two magnets leads to them breaking into small pieces.

No play value

Absolutely store magnets away from children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are fatal.

Safe distance

Data protection: Strong magnets can ruin payment cards and sensitive devices (pacemakers, medical aids, timepieces).

Allergy Warning

It is widely known that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and choose encased magnets.

GPS and phone interference

A strong magnetic field disrupts the functioning of compasses in phones and GPS navigation. Do not bring magnets close to a smartphone to prevent breaking the sensors.

ICD Warning

Warning for patients: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.

Handling rules

Exercise caution. Neodymium magnets act from a distance and connect with massive power, often faster than you can move away.

Heat warning

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.

Dust is flammable

Powder created during cutting of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Warning! Learn more about hazards in the article: Magnet Safety Guide.
