Magnetic force weakens drastically with every subsequent millimeter of gap. Remember that even a microscopic distance (e.g., dirt, paint, rust) strongly weakens the grip. Neodymiums hold optimally in perfect adhesion; distance nullifies the power. Notice how rapidly the load capacity plummet, when the magnet does not touch directly to the metal substrate. When planning the arrangement, discard unnecessary gaps.

When mounting a holder on a upright surface (e.g., a fridge), it will only hold just about 20%-30% of nominal attraction strength. Gravity as well as a low friction coefficient influence the fact that magnets move down faster than they detach. Planning a wall mount? Remember that the sliding force is significantly lower than the perpendicular breakaway force. On a slippery surface, the holder will slide down under a much lighter cargo. Using a rubber pad can effectively increase the grip.

A thin sheet is unable to focus the full magnetic flux, which squanders power of the magnet. If you mount a strong magnet to a weak sheet, the field will pass right through and the pull force will drop sharply. To squeeze 100% of this neodymium's power, you need a suitably thick backing of steel. The material oversaturation causes that on thin elements (e.g., car bodies), the holder holds weaker. We recommend selecting the steel dimension based on the following data.

Standard neodymium magnets change their properties parameters above the temperature limit. Protect against heat – heat can permanently destroy this product. With increasing heat, the magnet's force briefly lowers. Do not use this magnet close to heaters exceeding its operating temperature limit. Too high temperature will result in irreversible degradation of magnetism.
*Important note: Heat tolerance depends not only on the material grade, and the Permeance Coefficient Pc. Low-profile magnets (low permeance coefficient) may lose charge permanently under lower heat stress compared to rod magnets. Red status in the table points to a risk of irreversible loss for this specific geometry.

Two magnets attract each other from a much further distance than a neodymium and metal setup. The connection of two magnets produces a massive flux and a further horizon of performance. Want to build a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Exercise caution that when attracting two neodymiums, the collision energy is extreme. The levitation is marginally weaker than the connection force, but still large.
*Field value in repulsion mode reaches ~0 Gs at the midpoint between the magnets (due to field cancellation).
* Estimates apply to friction force of a pair of matching magnets (friction ~0.15 for Ni-Ni layer).

Extremely neodym field is a serious hazard to electronics as well as medical implants. These neodymiums generate a field that disrupts operation of digital equipment. Remember: the invisible magnetic field passes through tissues and glass. Increased vigilance must be taken by people with cochlear implants and insulin pumps. Also at risk are: automatic timepieces, remotes, membranes, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Neodymium magnets are prone to chipping – a strong collision with metal can result in shattering. Control the attraction moment – a neodymium left loose speeds with massive force. Striking energy can trigger coating fragments or dangerous crushing to skin. Be sure to control the product during installation so it doesn't hit with great force against the steel surface. A collision at high speed means shattering of the magnet. Wear safety glasses when handling with powerful specimens.

Corrosion 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. 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 retains just ~20% of its perpendicular strength.

2. Steel saturation

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

3. Thermal stability

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

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

chart generated for the permeance coefficient Pc (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 Pc (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 Pc 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 40x18x10 mm and a weight of 54 g, guarantees the highest quality connection. As a block magnet with high power (approx. 23.81 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. Watch your fingers! Magnets with a force of 23.81 kg can pinch very hard and cause hematomas. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.
Plate magnets MPL 40x18x10 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. They work great as invisible mounts under tiles, wood, or glass. 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. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. 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. In practice, this means that this magnet has the greatest attraction force on its main planes (40x18 mm), which is ideal for flat mounting. 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: 40 mm (length), 18 mm (width), and 10 mm (thickness). The key parameter here is the holding force amounting to approximately 23.81 kg (force ~233.58 N), which, with such a flat shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Strengths and weaknesses of rare earth magnets.

Pros

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:
  • Their strength is durable, and after approximately ten years it decreases only by ~1% (theoretically),
  • They maintain their magnetic properties even under external field action,
  • The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
  • Magnets possess impressive magnetic induction on the working surface,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • In view of the option of precise forming and customization to custom requirements, NdFeB magnets can be modeled in a wide range of shapes and sizes, which expands the range of possible applications,
  • Huge importance in future technologies – they are utilized in hard drives, motor assemblies, medical equipment, and technologically advanced constructions.
  • Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Weaknesses

Characteristics of disadvantages of neodymium magnets and proposals for their use:
  • At very strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
  • When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength 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
  • They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in creating threads and complex forms in magnets, we recommend using casing - magnetic mount.
  • Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Furthermore, tiny parts of these products can be problematic in diagnostics medical in case of swallowing.
  • With large orders the cost of neodymium magnets can be a barrier,

Lifting parameters

Highest magnetic holding force – what affects it?

The declared magnet strength concerns the maximum value, measured under laboratory conditions, namely:
  • on a block made of mild steel, effectively closing the magnetic flux
  • whose transverse dimension reaches at least 10 mm
  • with a plane perfectly flat
  • under conditions of ideal adhesion (metal-to-metal)
  • during pulling in a direction vertical to the plane
  • in temp. approx. 20°C

What influences lifting capacity in practice

In practice, the real power depends on several key aspects, ranked from most significant:
  • Gap between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
  • Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
  • Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
  • Plate material – low-carbon steel attracts best. Alloy admixtures decrease magnetic properties and holding force.
  • Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal weaken the grip.
  • Thermal environment – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate decreases the lifting capacity.

An intense magnetic field disrupts the functioning of compasses in phones and GPS navigation. Maintain magnets close to a smartphone to prevent damaging the sensors.

Material brittleness

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

Do not give to children

Only for adults. Small elements can be swallowed, leading to intestinal necrosis. Keep out of reach of children and animals.

Heat warning

Regular neodymium magnets (N-type) lose power when the temperature goes above 80°C. Damage is permanent.

Life threat

Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.

Nickel allergy

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness happens, cease handling magnets and use protective gear.

Threat to electronics

Very strong magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.

Powerful field

Use magnets with awareness. Their powerful strength can surprise even experienced users. Plan your moves and respect their force.

Fire warning

Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.

Bone fractures
