Pulling power decreases significantly with every mm of spacing. Keep in mind that even the smallest gap (e.g., dirt, paint, veneer) strongly reduces the pull force. Neodymiums operate strongest during direct contact; gap kills the power. Observe how flashily the parameters drop, when the magnet does not touch tightly to the metal substrate. When calculating the arrangement, discard additional spacers.

The following data calculates the theoretical shear load required to cause the slippage of the magnet downwards on a vertical steel plate (considering typical friction). This parameter varies with the separation distance between the magnet and the surface.

When hanging a holder on a upright surface (e.g., a board), it you can count on just approx. 20%-30% of its nominal power. Gravitational force and a weak degree of grip influence the fact that holders slide down faster than they pop off the substrate. Want to create a hanger? Consider that the sliding force is noticeably lower than the maximum static pull force. On a painted metal, the holder will give way down under a much lighter cargo. Using a rubber coating can drastically raise the stability.

A thin metal plate is not enough to absorb the entire magnetic field, which weakens actual performance of the magnet. Should you attach a powerful product to a too thin substrate, the flux will penetrate right through and the holding will be smaller. To achieve full efficiency of this neodymium's power, you need a suitably thick backing of metal. The material oversaturation causes that on sheet metal structures (e.g., appliance housings), the magnet holds weaker. We suggest choosing the steel thickness according to the table below.

Ordinary NdFeB products irreversibly lose power after exceeding the maximum temperature. Protect against heat – high temperature can irreversibly demagnetize this product. With increasing heat, the magnet's capacity briefly drops. Refrain from using this product close to ovens exceeding its safe range. Ignoring the limit will cause irreversible degradation of magnetism.

*Important note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Thin magnets (low permeance coefficient) may lose charge permanently under lower heat stress compared to rod magnets. Red status in the table signals permanent field degradation for this specific geometry.

Two strong neodymiums attract each other from a wider radius than a neodymium and metal combination. The setup of two magnets creates a more powerful interaction and a wider radius of action. Want to build a strong closure? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the pinch force is huge. The levitation is marginally weaker than the attraction, but still impressive.
*The magnetic induction in repulsion mode drops to ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
Note: Calculations refer to shear force of two identical neodymium magnets (friction ~0.15 for Ni-Ni plating).

Powerful magnet radiation poses a serious hazard to IT equipment and pacemakers. These NdFeB products generate a field that destroys function of digital equipment. Be aware: the invisible magnetic field penetrates the body and plastic. Exceptional care must be exercised by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, car keys, membranes, and screens. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Magnetic elements are very brittle – a violent impact against metal can result in shattering. Control the attraction moment – a neodymium left loose speeds with massive force. Striking energy can cause material chips or injury to fingers. Be sure to control the product during bringing near metal so it doesn't hit with great force against the steel surface. A contact at a velocity of dozens of km/h means shattering of the neodymium. Use safety goggles when playing with powerful specimens.

Rust risk: Standard nickel requires drying after every contact with moisture; lack of maintenance will lead to rust spots.

In water, the magnet feels stronger thanks to Archimedes' principle. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Wall mount (shear)

*Warning: On a vertical surface, the magnet holds merely a fraction of its perpendicular strength.

2. Steel saturation

*Thin steel (e.g. 0.5mm PC case) drastically reduces the holding force.

3. Temperature resistance

*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) = 0.38

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 magnet in the shape of a plate made of NdFeB material, which, with dimensions of 100x40x20 mm and a weight of 600 g, guarantees premium class connection. This magnetic block with a force of 1177.33 N is ready for shipment in 24h, allowing for rapid realization of your project. Additionally, its Ni-Cu-Ni coating protects 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. Watch your fingers! Magnets with a force of 120.01 kg can pinch very hard and cause hematomas. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

Plate magnets MPL 100x40x20 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. Thanks to the flat surface and high force (approx. 120.01 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. 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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 100x40x20 / N38 model is magnetized axially (dimension 20 mm), which means that the N and S poles are located on its largest, flat surfaces. In practice, this means that this magnet has the greatest attraction force on its main planes (100x40 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: 100 mm (length), 40 mm (width), and 20 mm (thickness). The key parameter here is the lifting capacity amounting to approximately 120.01 kg (force ~1177.33 N), which, with such a compact shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages and disadvantages of rare earth magnets.

Advantages

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

They have stable power, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
They have excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
By covering with a reflective layer of nickel, the element presents an modern look,
Neodymium magnets ensure maximum magnetic induction on a contact point, which increases force concentration,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to flexibility in forming and the capacity to modify to client solutions,
Key role in electronics industry – they find application in magnetic memories, brushless drives, medical equipment, and other advanced devices.
Thanks to their power density, small magnets offer high operating force, in miniature format,

Limitations

Characteristics of disadvantages of neodymium magnets: weaknesses and usage proposals

Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also increases their durability
When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as 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 start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
We suggest casing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated shapes.
Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these devices can be problematic in diagnostics medical after entering the body.
With budget limitations the cost of neodymium magnets is a challenge,

Pull force analysis

Highest magnetic holding force – what affects it?

The force parameter is a result of laboratory testing conducted under the following configuration:

with the application of a yoke made of special test steel, ensuring full magnetic saturation
possessing a massiveness of min. 10 mm to avoid saturation
with a plane cleaned and smooth
with direct contact (no impurities)
under perpendicular application of breakaway force (90-degree angle)
at temperature room level

Determinants of practical lifting force of a magnet

Effective lifting capacity is influenced by specific conditions, such as (from most important):

Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
Load vector – highest force is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Steel grade – ideal substrate is high-permeability steel. Cast iron may attract less.
Smoothness – ideal contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
Temperature – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.

Precautions when working with NdFeB magnets

Demagnetization risk

Control the heat. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.

Crushing force

Danger of trauma: The attraction force is so great that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.

ICD Warning

Individuals with a ICD should keep an absolute distance from magnets. The magnetism can disrupt the functioning of the implant.

Danger to the youngest

Strictly store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are life-threatening.

Allergic reactions

Medical facts indicate that the nickel plating (the usual finish) is a common allergen. If you have an allergy, avoid direct skin contact or select encased magnets.

Risk of cracking

Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.

Protect data

Do not bring magnets close to a purse, laptop, or screen. The magnetic field can permanently damage these devices and wipe information from cards.

Safe operation

Exercise caution. Neodymium magnets attract from a distance and snap with huge force, often quicker than you can move away.

Dust explosion hazard

Drilling and cutting of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Magnetic interference

Navigation devices and smartphones are highly sensitive to magnetism. Close proximity with a strong magnet can permanently damage the internal compass in your phone.
