Magnetic force decreases significantly with every mm of spacing. Remember that even the smallest gap (e.g., contamination, varnish, veneer) noticeably weakens the grip. Neodymiums hold strongest in perfect adhesion; gap nullifies the power. Notice how rapidly the pull force plummet, when the product does not touch flatly to the metal substrate. When planning the arrangement, discard redundant distances.

This section defines the approximate holding capacity needed to start the shifting of the magnet vertically on a upright steel plate (assuming standard friction). This value varies with the separation distance between the magnet and the surface.

When mounting a holder on a vertical wall (e.g., a fridge), it you can count on only about 20%-30% of its maximum pull force. Gravitational force as well as a weak degree of grip influence the fact that holders move down faster than they pop off the substrate. Want to create a wall mount? Consider that the shear force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the magnet will slide down under a significantly smaller weight. Utilizing a rubberized pad can significantly increase the grip.

A thin metal plate cannot conduct the entire magnetic field, which weakens actual performance of the magnet. If you mount a strong magnet to a weak sheet, the field will pass right through and the holding will be smaller. To achieve the maximum of this magnet's potential, you require a sufficiently solid element of steel. The saturation phenomenon causes that on delicate walls (e.g., car bodies), the holder holds weaker. We advise picking the steel dimension from these parameters.

Classic neodymiums irreversibly lose strength past the thermal threshold. Watch out for overheating – excessive heat can permanently demagnetize this product. With increasing heat, the magnet's force briefly drops. Do not use this magnet in hot environments exceeding its working range. Exceeding the critical threshold will result in destruction of magnetic properties.

*Technical advisory: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) are more susceptible to demagnetization at lower temperatures than long magnets. The danger warning in the table indicates permanent field degradation for this specific geometry.

Two strong neodymiums interact from a much further distance than a magnet and steel combination. The setup of two magnets produces a massive flux and a wider radius of action. Want to build a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when connecting a pair of magnets, the collision energy is extreme. The repulsion force is marginally weaker than the attraction, but still impressive.
*The magnetic induction in repulsion mode reaches ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Important: Results demonstrate friction force of two identical magnets (friction ~0.15 for Ni-Ni plating).

A strong magnetic field is a real danger to electronic devices and medical implants. These NdFeB products generate a flux that prevents correct functioning of sensitive medical devices. Be aware: the invisible magnetic field penetrates the body and housings. Increased vigilance must be exercised by people with hearing aids and drug dispensers. Also at risk are: automatic timepieces, car keys, membranes, and screens. Avoid contact with magnetic cards, hard drives, or sensitive navigation tools.

Neodymium magnets are prone to chipping – a violent impact against metal can result in shattering. Control the attraction moment – a magnet released freely speeds with massive force. Striking energy can trigger coating fragments or dangerous crushing to fingers. Hold the magnet firmly during installation so it doesn't slam with momentum against the metal. A collision at high speed ends with a crack of the neodymium. Use safety goggles when working with large magnets.

Corrosion warning: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

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

1. Vertical hold

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

2. Steel thickness impact

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.38

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.

Model MPL 100x40x20 / N38 features a flat shape and industrial pulling force, making it an ideal solution for building separators and machines. As a block magnet with high power (approx. 120.01 kg), this product is available off-the-shelf from our warehouse in Poland. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

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 100x40x20 / 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 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 100x40x20 / N38, it is best to use strong epoxy glues (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. Remember to clean and degrease 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 (100x40 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: 100 mm (length), 40 mm (width), and 20 mm (thickness). It is a magnetic block with dimensions 100x40x20 mm and a self-weight of 600 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Pros

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

Their strength remains stable, and after approximately ten years it decreases only by ~1% (according to research),
They retain their magnetic properties even under strong external field,
A magnet with a metallic silver surface has an effective appearance,
Magnetic induction on the surface of the magnet is extremely intense,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Considering the potential of flexible molding and adaptation to individualized projects, neodymium magnets can be modeled in a variety of forms and dimensions, which increases their versatility,
Versatile presence in modern industrial fields – they find application in HDD drives, motor assemblies, diagnostic systems, and other advanced devices.
Thanks to concentrated force, small magnets offer high operating force, in miniature format,

Cons

Drawbacks and weaknesses of neodymium magnets and ways of using them

They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
Due to limitations in realizing nuts and complicated shapes in magnets, we propose using a housing - magnetic holder.
Potential hazard resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these products can disrupt the diagnostic process medical when they are in the body.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Magnetic strength at its maximum – what it depends on?

The load parameter shown refers to the limit force, measured under ideal test conditions, meaning:

using a plate made of mild steel, serving as a ideal flux conductor
with a cross-section no less than 10 mm
characterized by smoothness
with total lack of distance (without impurities)
during pulling in a direction vertical to the plane
in stable room temperature

Practical lifting capacity: influencing factors

In practice, the real power depends on a number of factors, listed from crucial:

Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
Steel grade – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
Smoothness – full contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
Temperature – temperature increase results in weakening of force. Check the thermal limit for a given model.

Lifting capacity was assessed by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.

Safe handling of NdFeB magnets

Choking Hazard

Absolutely keep magnets away from children. Choking hazard is high, and the effects of magnets clamping inside the body are life-threatening.

Magnet fragility

Neodymium magnets are sintered ceramics, which means they are very brittle. Impact of two magnets leads to them breaking into small pieces.

Keep away from electronics

Navigation devices and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can permanently damage the internal compass in your phone.

Allergy Warning

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness appears, cease handling magnets and use protective gear.

Heat warning

Watch the temperature. Exposing the magnet to high heat will destroy its properties and pulling force.

Combustion hazard

Powder generated during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.

Physical harm

Risk of injury: The attraction force is so great that it can cause hematomas, crushing, and broken bones. Use thick gloves.

Keep away from computers

Equipment safety: Strong magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, timepieces).

Handling guide

Exercise caution. Rare earth magnets attract from a long distance and connect with massive power, often faster than you can react.

Life threat

Warning for patients: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or request help to work with the magnets.
