Pulling power weakens sharply with every subsequent millimeter of distance. Remember that every additional insulation layer (e.g., contamination, varnish, dust) strongly reduces the pull force. Neodymiums operate strongest at the point of direct contact; distance nullifies the power. Notice how rapidly the load capacity plummet, when the product does not adhere flatly to the steel surface. When designing the mounting, eliminate unnecessary gaps.

The table below defines the approximate holding capacity needed to cause the downward movement of the magnet down against a vertical steel wall (considering typical friction). This parameter is a function of the gap size between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
MPL 12x10x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	1.04 kg / 2.28 lbs 1035.0 g / 10.2 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.69 kg / 1.52 lbs 690.0 g / 6.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.35 kg / 0.76 lbs 345.0 g / 3.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.73 kg / 3.80 lbs 1725.0 g / 16.9 N

When mounting a element on a upright plane (e.g., a fridge), it you can count on just approx. 20%-30% of its nominal power. Gravitational force as well as a low friction coefficient mean that products slide down easier than they pop off the substrate. Designing a wall mount? Note that the sliding force is noticeably lower than the perpendicular breakaway force. On a slippery surface, the magnet will slide down under a noticeably lighter weight. Using a rubber pad can significantly improve the result.

A too thin steel is unable to absorb the entire magnetic field, which weakens actual performance of the magnet. If you mount a strong magnet to a thin surface, the magnetism will penetrate right through and the attraction force will be weaker. To squeeze full efficiency of this neodymium's potential, you need a suitably thick element of steel. The saturation effect causes that on thin elements (e.g., thin profiles), the magnet shows lower pull force. We recommend selecting the steel thickness from these parameters.

Classic neodymiums lose power after exceeding the maximum temperature. Protect against heat – heat can irreversibly damage this product. With increasing heat, the magnet's force briefly decreases. Avoid using this magnet close to ovens exceeding its safe range. Too high temperature will result in destruction of magnetic properties.

*Engineering note: Heat tolerance is determined by both grade, as well as the dimension ratios. Thin magnets (low permeance coefficient) are more susceptible to demagnetization at lower temperatures compared to rod magnets. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two magnets interact from a significantly greater distance than a magnet and steel setup. The connection of two magnets produces a massive flux and a wider radius of operation. Want to build a strong closure? Utilize two neodymiums instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the collision energy is extreme. The repulsion force is marginally weaker than the connection force, but still large.
*Field value between like poles is approximately ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
* Results demonstrate friction force of a pair of matching magnets (friction ~0.15 for Ni-Ni coating).

Extremely neodym field poses a serious hazard to IT equipment as well as pacemakers. These neodymiums produce a flux that disrupts operation of sensitive medical devices. Notice: the unseen radiation penetrates the body and housings. Exceptional care must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: automatic timepieces, car keys, membranes, and displays. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

NdFeB products are very brittle – a collision with steel causes immediate chipping. Control the attraction moment – a magnet released freely turns into a projectile. Impact energy can cause material chips or painful pinches to fingers. Hold the magnet firmly during bringing near metal so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear eye protection when playing with large magnets.

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

In water, the magnet feels stronger thanks to Archimedes' principle. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Vertical hold

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

2. Efficiency vs thickness

*Thin metal sheet (e.g. 0.5mm PC case) significantly weakens the holding force.

3. Thermal stability

*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) = 0.43

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 a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 12x10x4 mm and a weight of 3.6 g, guarantees premium class connection. As a magnetic bar with high power (approx. 3.45 kg), this product is available immediately from our warehouse in Poland. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

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 12x10x4 / 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 generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. 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. Remember to roughen and wash 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 (12x10 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.

The presented product is a neodymium magnet with precisely defined parameters: 12 mm (length), 10 mm (width), and 4 mm (thickness). It is a magnetic block with dimensions 12x10x4 mm and a self-weight of 3.6 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths and weaknesses of Nd₂Fe₁₄B magnets.

Strengths

Besides their remarkable field intensity, neodymium magnets offer the following advantages:

They do not lose magnetism, even during approximately ten years – the reduction in strength is only ~1% (theoretically),
Magnets perfectly defend themselves against demagnetization caused by external fields,
A magnet with a metallic nickel surface is more attractive,
Neodymium magnets generate maximum magnetic induction on a contact point, which ensures high operational effectiveness,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures reaching 230°C and above...
In view of the option of precise molding and adaptation to individualized projects, NdFeB magnets can be produced in a broad palette of forms and dimensions, which expands the range of possible applications,
Fundamental importance in high-tech industry – they serve a role in computer drives, electric motors, precision medical tools, as well as technologically advanced constructions.
Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,

Disadvantages

Drawbacks and weaknesses of neodymium magnets and ways of using them

To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its 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
They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
Due to limitations in realizing threads and complicated shapes in magnets, we recommend using cover - magnetic mount.
Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small components of these products are able to be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

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

Holding force of 3.45 kg is a result of laboratory testing conducted under the following configuration:

with the application of a sheet made of special test steel, guaranteeing full magnetic saturation
with a thickness of at least 10 mm
characterized by lack of roughness
with zero gap (without coatings)
during detachment in a direction vertical to the mounting surface
at temperature room level

Magnet lifting force in use – key factors

Bear in mind that the working load may be lower depending on elements below, in order of importance:

Clearance – existence of any layer (rust, dirt, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).

Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet and the plate decreases the load capacity.

H&S for magnets

Maximum temperature

Keep cool. NdFeB magnets are susceptible to heat. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Combustion hazard

Powder created during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.

Beware of splinters

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

Do not give to children

Adult use only. Tiny parts pose a choking risk, leading to serious injuries. Keep out of reach of kids and pets.

Life threat

Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.

Physical harm

Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!

Handling rules

Be careful. Rare earth magnets act from a long distance and snap with huge force, often quicker than you can react.

Safe distance

Equipment safety: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, timepieces).

Impact on smartphones

A powerful magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets near a smartphone to avoid breaking the sensors.

Skin irritation risks
