Grip strength decreases sharply with every subsequent millimeter of gap. Note that even the smallest gap (e.g., dirt, paint, veneer) noticeably reduces the pull force. Neodymiums hold strongest during direct contact; air break drastically cuts the force. Notice how quickly the pull force fall, when the magnet does not touch tightly to the steel surface. When designing the mounting, avoid unnecessary gaps.

The following data presents the estimated shear load required to start the downward movement of the magnet downwards on a upright steel plate (considering standard friction). This value is relative to the air gap between the magnet and the surface.

When mounting a holder on a vertical surface (e.g., a car body), it you can count on only about 20%-30% of its nominal power. Gravity and a low friction coefficient influence the fact that products move down faster than they pop off the substrate. Planning a hanger? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a smooth steel, the holder will give way down under a noticeably lighter weight. Application of an anti-slip layer can effectively increase the grip.

A thin metal plate is incapable of absorb the entire magnetic field, which weakens actual performance of the magnet. If you attach a powerful product to a too thin substrate, the magnetism will penetrate right through and the attraction force will be weaker. To utilize the maximum of this neodymium's potential, you require a sufficiently solid element of metal. The material oversaturation means that on delicate walls (e.g., appliance housings), the magnet works worse. We suggest choosing the steel dimension from these parameters.

Ordinary NdFeB products change their properties strength after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly destroy this product. With every degree above norm, the magnet's power momentarily drops. Refrain from using this magnet near heat sources exceeding its safe range. Too high temperature will result in destruction of magnetic properties.

*Important note: Thermal stability is determined by both grade, and the Permeance Coefficient Pc. Flat magnets (low Pc) may lose charge permanently sooner compared to rod magnets. Red status in the table signals permanent field degradation for this particular item.

Two strong neodymiums attract each other from a wider radius than a neodymium and metal setup. Such a system of magnet-to-magnet produces a massive flux and a larger range of operation. Designing a solid fastener? Apply two magnets instead of one magnet and a steel. Remember that when bringing together two magnets, the pinch force is extreme. The repulsion force is marginally weaker than the attraction, but still impressive.
*Field value in repulsion mode reaches ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Note: Figures demonstrate sliding force of two identical magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field poses a serious hazard to IT equipment and medical implants. These NdFeB products produce a flux that prevents correct functioning of digital equipment. Remember: the invisible magnetic field passes through tissues and housings. Exceptional care must be taken by people with hearing aids and drug dispensers. Influence will be felt by: mechanical watches, car keys, speakers, and displays. Do not bring the product near payment cards, HDD media, or precise measuring instruments.

Table 8: Dynamics (kinetic energy) - warning

50 mm	86.01 km/h (23.89 m/s)	0.31 J
100 mm	121.63 km/h (33.79 m/s)	0.63 J

NdFeB products are very brittle – a collision with steel risks their cracking. Control the attraction moment – a neodymium left loose turns into a projectile. Kinetic force can destroy the magnet or dangerous crushing to skin. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear eye protection when handling with powerful specimens.

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

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

*Warning: On a vertical wall, the magnet retains just approx. 20-30% of its max power.

2. Steel thickness impact

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

3. Temperature resistance

*For N38 material, the max working temp is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.48

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 7x7x3 / N38 features a low profile and industrial pulling force, making it an ideal solution for building separators and machines. As a magnetic bar with high power (approx. 1.60 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 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 1.60 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

They constitute a key element in the production of wind generators and material handling systems. Thanks to the flat surface and high force (approx. 1.60 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

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. 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. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. This is the most popular configuration for block magnets used in separators and holders.

The presented product is a neodymium magnet with precisely defined parameters: 7 mm (length), 7 mm (width), and 3 mm (thickness). It is a magnetic block with dimensions 7x7x3 mm and a self-weight of 1.1 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

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

They retain attractive force for around ten years – the drop is just ~1% (in theory),
They are noted for resistance to demagnetization induced by presence of other magnetic fields,
Thanks to the reflective finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an visually attractive appearance,
Neodymium magnets create maximum magnetic induction on a small area, which ensures high operational effectiveness,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of individual shaping and optimizing to complex conditions,
Key role in innovative solutions – they find application in hard drives, electromotive mechanisms, medical devices, and modern systems.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Weaknesses

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

At very strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets lose their power 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. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
Limited possibility of creating threads in the magnet and complex shapes - preferred is casing - mounting mechanism.
Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets are able to be problematic in diagnostics medical in case of swallowing.
Due to complex production process, their price exceeds standard values,

Holding force characteristics

Detachment force of the magnet in optimal conditions – what affects it?

Holding force of 1.60 kg is a result of laboratory testing executed under the following configuration:

on a block made of mild steel, effectively closing the magnetic field
whose transverse dimension reaches at least 10 mm
with an ideally smooth contact surface
under conditions of ideal adhesion (surface-to-surface)
for force acting at a right angle (pull-off, not shear)
at temperature room level

Practical aspects of lifting capacity – factors

In practice, the actual holding force results from many variables, listed from most significant:

Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Direction of force – maximum parameter is available only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
Base massiveness – insufficiently thick plate does not close the flux, causing part of the power to be lost to the other side.
Metal type – different alloys attracts identically. Alloy additives weaken the attraction effect.
Surface structure – the more even the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity was determined with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet and the plate decreases the holding force.

H&S for magnets

Dust explosion hazard

Mechanical processing of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.

Caution required

Be careful. Neodymium magnets act from a long distance and snap with massive power, often quicker than you can react.

This is not a toy

These products are not toys. Swallowing multiple magnets can lead to them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.

Data carriers

Do not bring magnets close to a wallet, computer, or screen. The magnetism can destroy these devices and wipe information from cards.

Material brittleness

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Nickel allergy

It is widely known that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, refrain from direct skin contact or opt for versions in plastic housing.

Finger safety

Mind your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!

Heat sensitivity

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.

Warning for heart patients

Medical warning: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.

Compass and GPS

An intense magnetic field negatively affects the operation of compasses in phones and GPS navigation. Do not bring magnets close to a device to prevent damaging the sensors.
