Pulling power decreases sharply with every subsequent millimeter of spacing. Keep in mind that even a microscopic distance (e.g., dirt, varnish, veneer) significantly diminishes the holding power. Neodymiums operate optimally at the point of direct contact; distance kills the power. See how flashily the parameters drop, when the magnet does not touch tightly to the metal substrate. When planning the arrangement, avoid unnecessary gaps.

This section calculates the estimated weight limit needed to start the slippage of the magnet vertically against a upright steel wall (considering standard friction coefficient). This value depends on the air gap between the magnet and the metal.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 3x3x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.10 kg / 0.22 LBS 102.0 g / 1.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.07 kg / 0.15 LBS 68.0 g / 0.7 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.03 kg / 0.07 LBS 34.0 g / 0.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	0.17 kg / 0.37 LBS 170.0 g / 1.7 N

When placing a magnet on a vertical wall (e.g., a fridge), it will maintain barely about 20%-30% of its nominal power. Gravity and a weak degree of grip cause that products move down easier than they detach. Planning a vertical fastening? Note that the sliding force is significantly lower than the perpendicular breakaway force. On a smooth steel, the element will slide down under a significantly smaller weight. Using a rubber layer can significantly raise the stability.

12 mm	100%	0.34 kg / 0.75 LBS 340.0 g / 3.3 N

A thin sheet cannot take in the entire magnetic field, which weakens actual performance of the magnet. Should you mount a strong magnet to a thin surface, the flux will pass right through and the holding will be smaller. To achieve the maximum of this neodymium's potential, you need a suitably thick element of metal. The material oversaturation causes that on delicate walls (e.g., appliance housings), the magnet shows lower pull force. We recommend selecting the steel thickness according to the table below.

Table 5: Thermal stability (material behavior) - thermal limit

Classic neodymiums lose power past the thermal threshold. Protect against heat – heat can permanently demagnetize this magnet. With every degree above norm, the neodymium's capacity momentarily drops. Do not use this product in hot environments higher than its operating temperature limit. Too high temperature will cause destruction of magnetism.

*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Flat magnets (low Pc) may lose charge permanently sooner than long magnets. The danger warning in the table points to a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a wider radius than a neodymium and metal setup. The setup of magnet-to-magnet creates a more powerful interaction and a larger range of operation. Planning to create a strong closure? Use a pair of magnets instead of a neodymium and a striker plate. Remember that when bringing together two magnets, the impact force is extreme. The repulsion force is a bit weaker than the connection force, but still impressive.
*Field value in repulsion mode is approximately ~0 Gs at the geometric center of the gap (resulting from vector opposition).
* Calculations refer to friction force of a pair of same magnets (friction ~0.15 for Ni-Ni coating).

A strong magnetic field poses a large risk to IT equipment as well as medical implants. These magnets produce a flux that destroys function of digital equipment. Be aware: the unseen radiation passes through tissues and glass. Special caution must be taken by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, remotes, membranes, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

NdFeB products are prone to chipping – a collision with steel causes immediate chipping. Watch the impact speed – a magnet released freely becomes dangerous. Striking energy can cause material chips or painful pinches to skin. Always hold the magnet during bringing near metal so it doesn't hit with great force against the metal. A collision at high speed almost guarantees destruction of the neodymium. Wear safety glasses when working with large magnets.

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

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

1. Wall mount (shear)

*Caution: On a vertical wall, the magnet holds only ~20% of its nominal pull.

2. Steel thickness impact

*Thin metal sheet (e.g. computer case) severely weakens the holding force.

3. Temperature resistance

*For N38 grade, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.84

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.

Component MPL 3x3x3 / N38 features a low profile and professional pulling force, making it an ideal solution for building separators and machines. As a magnetic bar with high power (approx. 0.34 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.

Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 3x3x3 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, 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. 0.34 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.

For mounting flat magnets MPL 3x3x3 / N38, we recommend utilizing two-component adhesives (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. Remember to roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 3x3x3 / N38 model is magnetized through the thickness (dimension 3 mm), which means that the N and S poles are located on its largest, flat surfaces. 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.

This model is characterized by dimensions 3x3x3 mm, which, at a weight of 0.2 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 3x3x3 mm and a self-weight of 0.2 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths as well as weaknesses of rare earth magnets.

Pros

Besides their exceptional magnetic power, neodymium magnets offer the following advantages:

They do not lose power, even after approximately ten years – the reduction in power is only ~1% (based on measurements),
They are noted for resistance to demagnetization induced by external disturbances,
The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
Magnetic induction on the top side of the magnet turns out to be very high,
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...
Possibility of individual shaping as well as modifying to precise requirements,
Significant place in modern technologies – they find application in hard drives, electromotive mechanisms, medical equipment, also complex engineering applications.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Disadvantages

Disadvantages of NdFeB magnets:

At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
Limited possibility of making threads in the magnet and complicated shapes - preferred is cover - mounting mechanism.
Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Additionally, small components of these magnets can be problematic in diagnostics medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum lifting force for a neodymium magnet – what contributes to it?

Magnet power is the result of a measurement for the most favorable conditions, including:

on a base made of structural steel, perfectly concentrating the magnetic field
possessing a massiveness of min. 10 mm to avoid saturation
characterized by smoothness
without the slightest insulating layer 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

In practice, the actual holding force results from a number of factors, listed from the most important:

Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of nominal force).
Plate thickness – too thin steel does not accept the full field, causing part of the flux to be wasted into the air.
Material type – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
Smoothness – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate lowers the load capacity.

H&S for magnets

Serious injuries

Large magnets can break fingers in a fraction of a second. Under no circumstances put your hand between two attracting surfaces.

Medical interference

Patients with a heart stimulator should maintain an absolute distance from magnets. The magnetic field can disrupt the operation of the life-saving device.

Protective goggles

Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets will cause them cracking into small pieces.

Adults only

Product intended for adults. Small elements pose a choking risk, leading to serious injuries. Keep away from children and animals.

Conscious usage

Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.

Sensitization to coating

Studies show that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, prevent touching magnets with bare hands and select coated magnets.

Do not overheat magnets

Standard neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. The loss of strength is permanent.

Threat to navigation

A strong magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Keep magnets near a device to prevent breaking the sensors.

Electronic hazard

Powerful magnetic fields can erase data on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.

Do not drill into magnets

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

Danger! Details about risks in the article: Safety of working with magnets.
