Pulling power weakens significantly per each millimeter of distance. Keep in mind that every additional insulation layer (e.g., dirt, paint, veneer) significantly reduces the pull force. Magnets hold optimally during direct contact; air break nullifies the force. Observe how flashily the pull force fall, when the magnet does not adhere tightly to the metal substrate. When calculating the mounting, avoid unnecessary gaps.

The table below calculates the estimated holding capacity needed to start the slippage of the magnet vertically against a vertical metal surface (considering standard friction). This parameter depends on the separation distance between the magnet and the surface.

Table 3: Vertical assembly (shearing) - vertical pull

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	10.12 kg / 22.31 lbs 10119.0 g / 99.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	6.75 kg / 14.87 lbs 6746.0 g / 66.2 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	3.37 kg / 7.44 lbs 3373.0 g / 33.1 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	16.87 kg / 37.18 lbs 16865.0 g / 165.4 N

When hanging a holder on a vertical wall (e.g., a board), it will only hold just approx. 20%-30% of its maximum pull force. Gravitational force as well as a low friction coefficient cause that products move down easier than they pop off the substrate. Want to create a vertical fastening? Remember that the shear force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the magnet will slip down under a much lighter cargo. Application of an anti-slip coating can significantly increase the grip.

A thin sheet is unable to conduct the entire magnetic field, which wastes potential of the holder. Should you install a neodymium to a weak sheet, the magnetism will pass right through and the holding will be smaller. To achieve full efficiency of this magnet's power, you need a suitably thick piece of metal. The saturation phenomenon means that on delicate walls (e.g., car bodies), the holder shows lower pull force. We advise picking the steel thickness based on the following data.

Classic neodymiums change their properties power above the temperature limit. Avoid high temperatures – heat can permanently damage this product. With every degree above norm, the magnet's force temporarily drops. Do not use this magnet near heat sources exceeding its operating temperature limit. Too high temperature will result in destruction of magnetism.

*Engineering note: Thermal stability depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) are more susceptible to demagnetization sooner compared to rod magnets. The danger warning in the table points to permanent field degradation for this particular item.

Two magnetic products attract each other from a wider radius than a neodymium and metal combination. The setup of magnet-to-magnet produces a massive flux and a wider radius of performance. Planning to create a strong closure? Use a pair of magnets instead of one magnet and a striker plate. Exercise caution that when bringing together two magnets, the collision energy is massive. The repulsion force is slightly lower than the attraction, but still impressive.
*Flux density between like poles reaches ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
* Calculations refer to friction force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

A strong magnetic field is a serious hazard to electronic devices and medical implants. These NdFeB products produce a field that destroys function of digital equipment. Be aware: the invisible magnetic field passes through tissues and housings. Increased vigilance must be exercised by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, car keys, membranes, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Neodymium magnets are very brittle – a collision with steel risks their cracking. Control the attraction moment – a neodymium left loose turns into a projectile. Impact energy can trigger coating fragments or painful pinches to skin. Hold the magnet firmly during bringing near metal 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.

In water, the magnet feels stronger thanks to Archimedes' principle. Buoyancy helps in lifting finds.

1. Vertical hold

*Warning: On a vertical wall, the magnet holds merely ~20% of its perpendicular strength.

2. Steel saturation

*Thin steel (e.g. computer case) severely 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) = 0.26

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 an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 50x50x10 mm and a weight of 187.5 g, guarantees premium class connection. As a magnetic bar with high power (approx. 33.73 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.

The key to success is sliding 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 50x50x10 / 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 50x50x10 / N38, we recommend utilizing two-component adhesives (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. 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. 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.

The presented product is a neodymium magnet with precisely defined parameters: 50 mm (length), 50 mm (width), and 10 mm (thickness). It is a magnetic block with dimensions 50x50x10 mm and a self-weight of 187.5 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Strengths

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

Their magnetic field is maintained, and after approximately 10 years it drops only by ~1% (theoretically),
They have excellent resistance to weakening of magnetic properties due to external fields,
By applying a decorative layer of nickel, the element has an nice look,
Neodymium magnets achieve maximum magnetic induction on a small surface, which increases force concentration,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to flexibility in forming and the ability to customize to client solutions,
Wide application in innovative solutions – they find application in data components, drive modules, precision medical tools, also technologically advanced constructions.
Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Limitations

Disadvantages of neodymium magnets:

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
We warn that neodymium magnets can reduce their power 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 recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
Due to limitations in creating threads and complex forms in magnets, we recommend using casing - magnetic mount.
Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Furthermore, tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
Due to neodymium price, their price is relatively high,

Pull force analysis

Optimal lifting capacity of a neodymium magnet – what it depends on?

The lifting capacity listed is a theoretical maximum value executed under standard conditions:

on a block made of mild steel, effectively closing the magnetic flux
with a cross-section minimum 10 mm
with a surface cleaned and smooth
with direct contact (no coatings)
during detachment in a direction perpendicular to the plane
at standard ambient temperature

Impact of factors on magnetic holding capacity in practice

During everyday use, the actual lifting capacity is determined by several key aspects, ranked from the most important:

Air gap (betwixt the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to paint, rust or debris).
Direction of force – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
Material type – the best choice is pure iron steel. Hardened steels may have worse magnetic properties.
Smoothness – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
Thermal factor – hot environment reduces magnetic field. Too high temperature can permanently damage the magnet.

Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the holding force is lower. In addition, even a slight gap between the magnet and the plate lowers the load capacity.

Precautions when working with neodymium magnets

Danger to the youngest

Adult use only. Small elements pose a choking risk, leading to severe trauma. Store out of reach of kids and pets.

Serious injuries

Watch your fingers. Two large magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!

Machining danger

Combustion risk: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.

Data carriers

Intense magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.

Heat sensitivity

Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.

Magnet fragility

Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Powerful field

Use magnets consciously. Their huge power can surprise even professionals. Be vigilant and do not underestimate their power.

Health Danger

Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.

Skin irritation risks

Nickel alert: The Ni-Cu-Ni coating contains nickel. If redness occurs, immediately stop handling magnets and use protective gear.

GPS and phone interference

A powerful magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Keep magnets near a device to prevent breaking the sensors.
