Magnetic force decreases drastically with every mm of gap. Remember that every additional insulation layer (e.g., contamination, paint, dust) noticeably reduces the pull force. Magnetic products hold most effectively at the point of direct contact; air break nullifies the power. Notice how rapidly the load capacity drop, when the magnet does not touch directly to the metal substrate. When designing the assembly, eliminate unnecessary gaps.

The table below shows the theoretical shear load needed to initiate the slippage of the magnet down against a vertical metal surface (considering standard friction). This value varies with the gap size between the magnet and the surface.

When hanging a magnet on a upright plane (e.g., a car body), it you can count on barely approx. 20%-30% of its nominal power. Gravitational force as well as a low friction coefficient cause that magnets slip easier than they detach. Designing a hanger? Note that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the element will slip down under a much lighter load. Application of an anti-slip layer can drastically increase the grip.

A thin sheet is not enough to conduct the full magnetic flux, which wastes potential of the magnet. Should you mount a strong magnet to a too thin substrate, the flux will pass right through and the pull force will drop sharply. To achieve full efficiency of this neodymium's potential, you need a suitably thick piece of steel. The saturation phenomenon means that on thin elements (e.g., car bodies), the product holds weaker. We suggest choosing the steel dimension from these parameters.

Standard neodymium magnets change their properties parameters after exceeding the maximum temperature. Avoid high temperatures – high temperature can irreversibly demagnetize this magnet. As the temperature rises, the magnet's capacity temporarily drops. Do not use this magnet close to heaters higher than its operating temperature limit. Exceeding the critical threshold will result in irreversible degradation of magnetism.

*Engineering note: Temperature resistance 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 permanent field degradation for this particular item.

Two magnetic products interact from a much further distance than a neodymium and metal setup. The connection of magnet-to-magnet creates a more powerful interaction and a larger range of performance. Planning to create a powerful holder? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when attracting two neodymiums, the collision energy is huge. The levitation is marginally weaker than the attraction, but still significant.
*The magnetic induction between like poles reaches ~0 Gs at the geometric center of the gap (resulting from vector opposition).
Important: Results show sliding force of dual matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field poses a real danger to IT equipment as well as pacemakers. These magnets produce a field that prevents correct functioning of digital equipment. Be aware: the unseen radiation acts through matter and glass. Exceptional care must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, car keys, speakers, and screens. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Neodymium magnets are delicate – a strong collision with metal risks their cracking. Pay attention to connection velocity – a magnet released freely turns into a projectile. Striking energy can destroy the magnet or painful pinches to skin. Hold the magnet firmly during mounting so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h means shattering of the magnet. Wear safety glasses when playing with powerful specimens.

Rust risk: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

Water displaces steel, making heavy objects slightly lighter. Buoyancy helps in lifting finds.

1. Sliding resistance

*Warning: On a vertical surface, the magnet retains only a fraction of its perpendicular strength.

2. Steel saturation

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

3. Power loss vs temp

*For standard magnets, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.54

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 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.

Model MPL 50x50x25 / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. As a block magnet with high power (approx. 90.53 kg), this product is available off-the-shelf 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 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. Watch your fingers! Magnets with a force of 90.53 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 wind generators and material handling systems. 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 50x50x25 / N38, we recommend utilizing strong epoxy glues (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 50x50x25 / N38 model is magnetized axially (dimension 25 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 (50x50 mm), which is ideal for flat mounting. 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: 50 mm (length), 50 mm (width), and 25 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 90.53 kg (force ~888.15 N), which, with such a flat shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Pros as well as cons of neodymium magnets.

Strengths

In addition to their pulling strength, neodymium magnets provide the following advantages:

They retain attractive force for around 10 years – the drop is just ~1% (according to analyses),
They are extremely resistant to demagnetization induced by external disturbances,
A magnet with a smooth nickel surface looks better,
They feature high magnetic induction at the operating surface, which improves attraction properties,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures reaching 230°C and above...
Possibility of custom forming as well as adapting to individual conditions,
Versatile presence in modern technologies – they find application in magnetic memories, drive modules, precision medical tools, as well as industrial machines.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in small systems

Weaknesses

Disadvantages of NdFeB magnets:

At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets lose their force 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
Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
We suggest casing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated shapes.
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. It is also worth noting that small components of these devices are able to complicate diagnosis medical after entering the body.
With budget limitations the cost of neodymium magnets is a challenge,

Lifting parameters

Maximum magnetic pulling force – what contributes to it?

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

with the contact of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
possessing a massiveness of at least 10 mm to avoid saturation
with an ideally smooth touching surface
under conditions of ideal adhesion (metal-to-metal)
during detachment in a direction vertical to the mounting surface
at temperature room level

Lifting capacity in practice – influencing factors

Bear in mind that the magnet holding will differ subject to the following factors, in order of importance:

Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Material type – the best choice is pure iron steel. Hardened steels may attract less.
Surface finish – ideal contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
Temperature – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity was assessed by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the load capacity.

Warnings

Crushing risk

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

Pacemakers

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

Impact on smartphones

A strong magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets near a device to prevent damaging the sensors.

Dust is flammable

Mechanical processing of neodymium magnets carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Safe distance

Powerful magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.

Heat sensitivity

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.

Material brittleness

NdFeB magnets are ceramic materials, which means they are very brittle. Collision of two magnets leads to them cracking into small pieces.

Handling rules

Before starting, check safety instructions. Sudden snapping can break the magnet or injure your hand. Think ahead.

Warning for allergy sufferers

Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, cease working with magnets and use protective gear.

Keep away from children

Product intended for adults. Small elements pose a choking risk, causing severe trauma. Store out of reach of children and animals.
