Pulling power decreases significantly per each millimeter of spacing. Keep in mind that even a microscopic distance (e.g., dirt, varnish, rust) strongly diminishes the holding power. Magnetic products operate optimally in perfect adhesion; distance drastically cuts the power. Analyze how flashily the pull force drop, when the magnet does not adhere directly to the metal substrate. When planning the arrangement, discard additional spacers.

The following data indicates the theoretical holding capacity necessary to start the slippage of the magnet downwards against a upright steel plate (considering typical friction). This parameter is relative to the distance between the magnet and the metal.

Raw steel	µ = 0.3 30% Nominalnej Siły	9.00 kg / 19.83 lbs 8997.0 g / 88.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	6.00 kg / 13.22 lbs 5998.0 g / 58.8 N

When hanging a magnet on a vertical surface (e.g., a car body), it will only hold only approx. 20%-30% of its nominal power. Gravity and a weak degree of grip cause that holders slip faster than they pull off. Planning a vertical fastening? Remember that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the holder will slide down under a much lighter load. Application of an anti-slip coating can drastically improve the result.

A thin sheet is not enough to take in the full magnetic flux, which squanders power of the holder. If you install a neodymium to a weak sheet, the magnetism will penetrate right through and the holding will be smaller. To achieve the maximum of this neodymium's potential, you need a suitably thick piece of metal. The saturation phenomenon means that on delicate walls (e.g., appliance housings), the magnet works worse. We suggest choosing the steel dimension based on the following data.

Ordinary NdFeB products change their properties strength after exceeding the maximum temperature. Avoid high temperatures – high temperature can irreversibly destroy this product. With every degree above norm, the magnet's power momentarily decreases. Avoid using this magnet close to heaters higher than its safe range. Too high temperature will result in irreversible degradation of magnetism.

*Important note: Temperature resistance depends not only on the material grade, as well as the dimension ratios. Low-profile magnets (low permeance coefficient) are more susceptible to demagnetization sooner than long magnets. Red status in the table points to a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a significantly greater distance than a magnet and sheet setup. The connection of magnet-to-magnet generates a stronger field and a further horizon of performance. Want to build a powerful holder? Use a pair of magnets instead of a neodymium and a striker plate. Be careful that when bringing together two magnets, the collision energy is huge. The levitation is slightly lower than the attraction, but still large.
*Field value in repulsion mode is approximately ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
* Results refer to shear force of dual identical neodymium magnets (friction ~0.15 for Ni-Ni layer).

Powerful magnet radiation is a serious hazard to electronic devices as well as pacemakers. These magnets produce a flux that disrupts operation of sensitive medical devices. Be aware: the unseen radiation passes through tissues and housings. Increased vigilance must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, remotes, speakers, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

NdFeB products are prone to chipping – a violent impact against metal can result in shattering. Control the attraction moment – a neodymium left loose speeds with massive force. Kinetic force can cause material chips or painful pinches to fingers. Be sure to control the product during mounting so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the neodymium. Wear safety glasses when playing with large magnets.

Contrary to myths, water does not block the magnetic field. 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 just ~20% of its perpendicular strength.

2. Efficiency vs thickness

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

3. Temperature resistance

*For N38 material, 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.

This product is an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 50x20x10 mm and a weight of 75 g, guarantees premium class connection. As a block magnet with high power (approx. 29.99 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 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 50x20x10 / 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. 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. Thanks to the flat surface and high force (approx. 29.99 kg), they are ideal as closers in furniture making and mounting elements in automation. 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. 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. In practice, this means that this magnet has the greatest attraction force on its main planes (50x20 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.

This model is characterized by dimensions 50x20x10 mm, which, at a weight of 75 g, makes it an element with high energy density. The key parameter here is the holding force amounting to approximately 29.99 kg (force ~294.15 N), which, with such a compact shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Advantages as well as disadvantages of rare earth magnets.

Advantages

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

They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
Magnets effectively protect themselves against demagnetization caused by foreign field sources,
A magnet with a metallic silver surface has an effective appearance,
They feature high magnetic induction at the operating surface, which improves attraction properties,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Due to the possibility of precise shaping and customization to unique needs, NdFeB magnets can be created in a broad palette of shapes and sizes, which expands the range of possible applications,
Significant place in modern technologies – they serve a role in hard drives, electric drive systems, precision medical tools, also modern systems.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

Characteristics of disadvantages of neodymium magnets and proposals for their use:

At very strong impacts they can crack, therefore we recommend placing them in special holders. 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
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 prevent oxidation as well as corrosion.
We recommend cover - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated shapes.
Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these products are able to complicate diagnosis medical after entering the body.
With mass production the cost of neodymium magnets is a challenge,

Lifting parameters

Maximum lifting force for a neodymium magnet – what affects it?

Holding force of 29.99 kg is a result of laboratory testing executed under standard conditions:

on a block made of mild steel, perfectly concentrating the magnetic flux
with a thickness minimum 10 mm
with an polished contact surface
without the slightest air gap between the magnet and steel
for force acting at a right angle (in the magnet axis)
in stable room temperature

Lifting capacity in practice – influencing factors

It is worth knowing that the working load will differ depending on the following factors, in order of importance:

Gap between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
Metal type – not every steel attracts identically. Alloy additives weaken the attraction effect.
Surface structure – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
Temperature – temperature increase results in weakening of force. Check 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 detachment force, in contrast under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet and the plate decreases the load capacity.

Safe handling of neodymium magnets

Precision electronics

GPS units and smartphones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.

Magnetic media

Data protection: Strong magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).

Powerful field

Be careful. Neodymium magnets attract from a distance and connect with huge force, often faster than you can react.

Magnets are brittle

NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets will cause them cracking into shards.

Physical harm

Pinching hazard: The attraction force is so immense that it can result in blood blisters, pinching, and broken bones. Use thick gloves.

Power loss in heat

Control the heat. Exposing the magnet to high heat will destroy its properties and strength.

Do not give to children

NdFeB magnets are not suitable for play. Swallowing multiple magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and necessitates urgent medical intervention.

Nickel allergy

Medical facts indicate that nickel (standard magnet coating) is a strong allergen. If you have an allergy, refrain from touching magnets with bare hands or select encased magnets.

Machining danger

Machining of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Medical interference

Individuals with a heart stimulator have to keep an safe separation from magnets. The magnetism can disrupt the functioning of the implant.
