Magnetic force weakens drastically per each millimeter of spacing. Remember that even a microscopic distance (e.g., contamination, varnish, rust) noticeably reduces the pull force. Neodymiums work most effectively in perfect adhesion; air break nullifies the power. Observe how flashily the parameters fall, when the magnet does not adhere directly to the steel surface. When calculating the arrangement, eliminate unnecessary gaps.

This section calculates the approximate shear load necessary to initiate the slippage of the magnet down against a upright steel plate (assuming typical friction). This parameter is relative to the gap size between the magnet and the surface.

When placing a holder on a upright surface (e.g., a board), it you can count on only about 1/5 of its maximum pull force. Gravitational force and a weak degree of grip cause that products slip faster than they pop off the substrate. Want to create a vertical fastening? Note that the shear force is significantly lower than the perpendicular breakaway force. On a painted metal, the holder will give way down under a much lighter cargo. Application of an anti-slip pad can significantly improve the result.

A too thin steel cannot take in the entire magnetic field, which wastes potential of the magnet. Should you mount a strong magnet to a weak sheet, the field will pass right through and the pull force will drop sharply. To achieve the maximum of this magnet's potential, you need a suitably thick piece of metal. The saturation effect means that on thin elements (e.g., thin profiles), the magnet shows lower pull force. We recommend selecting the steel thickness based on the following data.

Standard neodymium magnets change their properties strength past the thermal threshold. Protect against heat – high temperature can irreversibly demagnetize this product. With every degree above norm, the neodymium's capacity briefly decreases. Refrain from using this magnet close to ovens exceeding its working range. Too high temperature will lead to permanent loss of magnetism.

*Important note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) may lose charge permanently at lower temperatures compared to rod magnets. The danger warning in the table points to permanent field degradation for this specific geometry.

Two magnetic products attract each other from a wider radius than a neodymium and metal setup. The connection of magnet-to-magnet produces a massive flux and a further horizon of performance. Want to build a powerful holder? Use a pair of magnets instead of one magnet and a striker plate. Remember that when bringing together two magnets, the pinch force is extreme. The levitation is slightly lower than the connection force, but still significant.
*The magnetic induction for N-N configuration reaches ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Attention: Estimates demonstrate friction force of dual matching neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a real danger to electronic devices and medical implants. These NdFeB products produce a flux that disrupts operation of digital equipment. Notice: the unseen radiation acts through matter and housings. Exceptional care must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, remotes, membranes, and screens. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Magnetic elements are very brittle – a strong collision with metal can result in shattering. Pay attention to connection velocity – a neodymium left loose becomes dangerous. Kinetic force can cause material chips or painful pinches to fingers. Be sure to control the product during bringing near metal so it doesn't hit violently against the metal. A collision at high speed almost guarantees destruction of the neodymium. Wear eye protection when handling with large magnets.

1. Vertical hold

*Caution: On a vertical surface, the magnet holds only a fraction of its max power.

2. Steel saturation

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

3. Power loss vs temp

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.36

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.

This product is a very powerful plate magnet made of NdFeB material, which, with dimensions of 45x25x10 mm and a weight of 84.38 g, guarantees premium class connection. As a block magnet with high power (approx. 28.48 kg), this product is available immediately from our warehouse in Poland. Additionally, its Ni-Cu-Ni coating protects 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. Watch your fingers! Magnets with a force of 28.48 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 45x25x10 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. Thanks to the flat surface and high force (approx. 28.48 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 45x25x10 / 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 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 (45x25 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 45x25x10 mm, which, at a weight of 84.38 g, makes it an element with high energy density. It is a magnetic block with dimensions 45x25x10 mm and a self-weight of 84.38 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of rare earth magnets.

Pros

Apart from their consistent power, neodymium magnets have these key benefits:

They have unchanged lifting capacity, and over more than 10 years their performance decreases symbolically – ~1% (according to theory),
They retain their magnetic properties even under close interference source,
By applying a shiny coating of silver, the element presents an proper look,
Magnetic induction on the working part of the magnet turns out to be extremely intense,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
Possibility of individual forming as well as optimizing to atypical needs,
Wide application in high-tech industry – they are used in HDD drives, electric drive systems, advanced medical instruments, as well as other advanced devices.
Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Problematic aspects of neodymium magnets: application proposals

At very strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
Limited possibility of making nuts in the magnet and complex forms - preferred is cover - mounting mechanism.
Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Optimal lifting capacity of a neodymium magnet – what contributes to it?

Holding force of 28.48 kg is a theoretical maximum value conducted under standard conditions:

using a plate made of high-permeability steel, functioning as a magnetic yoke
whose transverse dimension is min. 10 mm
with a surface cleaned and smooth
without any air gap between the magnet and steel
for force applied at a right angle (pull-off, not shear)
at temperature approx. 20 degrees Celsius

Magnet lifting force in use – key factors

Real force is influenced by working environment parameters, mainly (from most important):

Clearance – the presence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
Direction of force – maximum parameter is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Material type – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

Warnings

Shattering risk

Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.

Danger to pacemakers

For implant holders: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or request help to handle the magnets.

Skin irritation risks

Studies show that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, prevent direct skin contact or select versions in plastic housing.

Caution required

Before starting, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.

Machining danger

Combustion risk: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.

Electronic hazard

Do not bring magnets close to a purse, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.

Magnetic interference

A strong magnetic field interferes with the operation of magnetometers in smartphones and navigation systems. Do not bring magnets close to a device to avoid breaking the sensors.

Maximum temperature

Keep cool. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).

Bodily injuries

Pinching hazard: The pulling power is so great that it can result in hematomas, pinching, and even bone fractures. Protective gloves are recommended.

Choking Hazard

Product intended for adults. Small elements can be swallowed, leading to serious injuries. Keep away from children and animals.
