Magnetic force decreases significantly with every mm of gap. Remember that even a very thin break (e.g., contamination, paint, rust) noticeably reduces the pull force. Neodymiums hold strongest at the point of direct contact; distance kills the power. Notice how flashily the load capacity drop, when the product does not touch directly to the metal substrate. When designing the mounting, avoid additional spacers.

The following data indicates the estimated force necessary to initiate the sliding of the magnet downwards on a vertical steel wall (considering typical friction coefficient). The holding force is relative to the separation distance between the magnet and the surface.

When hanging a holder on a upright plane (e.g., a car body), it you can count on barely approx. 1/5 of its maximum pull force. Gravitational force as well as a weak degree of grip cause that holders move down faster than they detach. Designing a hanger? Remember that the shear force is much weaker than the perpendicular breakaway force. On a slippery surface, the holder will slip down under a much lighter load. Application of an anti-slip coating can significantly raise the stability.

A thin sheet cannot absorb the full magnetic flux, which squanders power of the magnet. If you install a neodymium to a weak sheet, the flux will pass right through and the attraction force will be weaker. To utilize the maximum of this neodymium's potential, you require a sufficiently solid backing of metal. The material oversaturation means that on thin elements (e.g., car bodies), the holder shows lower pull force. We recommend selecting the steel thickness from these parameters.

Ordinary NdFeB products lose power after exceeding the maximum temperature. Watch out for overheating – heat can irreversibly destroy this product. As the temperature rises, the neodymium's power briefly lowers. Refrain from using this magnet close to ovens exceeding its safe range. Exceeding the critical threshold will cause irreversible degradation of magnetism.

*Engineering note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Thin magnets (low Pc) risk losing magnetic properties under lower heat stress than taller cylinders. Warning indicator in the table points to a risk of irreversible loss for this particular item.

Two magnetic products attract each other from a wider radius than a magnet and steel combination. The setup of two magnets produces a massive flux and a larger range of operation. Want to build a powerful holder? Apply two magnets instead of one magnet and a striker plate. Exercise caution that when attracting two neodymiums, the collision energy is massive. The repulsion force is a bit weaker than the connection force, but still impressive.
*Field value for N-N configuration reaches ~0 Gs at the geometric center between the magnets (caused by magnetic field nullification).
Attention: Calculations show shear force of dual identical magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field is a real danger to electronic devices and medical implants. These magnets produce a flux that prevents correct functioning of sensitive medical devices. Notice: the unseen radiation penetrates the body and glass. Special caution must be exercised by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, 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 causes immediate chipping. Control the attraction moment – a neodymium left loose speeds with massive force. Impact energy can trigger coating fragments or painful pinches to fingers. Always hold the magnet during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed means shattering of the neodymium. Wear eye protection when playing with large magnets.

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

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Shear force

*Note: On a vertical wall, the magnet retains just approx. 20-30% of its nominal pull.

2. Steel thickness impact

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

3. Heat tolerance

*For N38 grade, the critical limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.40

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 an extremely strong magnet in the shape of a plate made of NdFeB material, which, with dimensions of 50x25x12 mm and a weight of 112.5 g, guarantees the highest quality connection. As a magnetic bar with high power (approx. 37.12 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 block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 50x25x12 / 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.

Plate magnets MPL 50x25x12 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. 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. 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).

Standardly, the MPL 50x25x12 / N38 model is magnetized axially (dimension 12 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 (50x25 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: 50 mm (length), 25 mm (width), and 12 mm (thickness). The key parameter here is the holding force amounting to approximately 37.12 kg (force ~364.18 N), which, with such a compact shape, proves the high grade of the material. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Pros

Besides their remarkable strength, neodymium magnets offer the following advantages:

They retain full power for around 10 years – the drop is just ~1% (based on simulations),
Neodymium magnets are exceptionally resistant to demagnetization caused by magnetic disturbances,
The use of an refined finish of noble metals (nickel, gold, silver) causes the element to present itself better,
Magnetic induction on the working layer of the magnet is strong,
Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
Considering the ability of accurate molding and adaptation to custom requirements, NdFeB magnets can be modeled in a variety of shapes and sizes, which makes them more universal,
Huge importance in innovative solutions – they are commonly used in mass storage devices, drive modules, medical equipment, also multitasking production systems.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also raises their durability
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 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 and corrosion.
We recommend a housing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complicated shapes.
Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these devices can be problematic in diagnostics medical when they are in the body.
Due to neodymium price, their price exceeds standard values,

Lifting parameters

Maximum lifting capacity of the magnet – what it depends on?

The specified lifting capacity concerns the maximum value, obtained under laboratory conditions, specifically:

using a base made of mild steel, acting as a magnetic yoke
possessing a massiveness of min. 10 mm to avoid saturation
with a surface free of scratches
with zero gap (without paint)
under vertical application of breakaway force (90-degree angle)
in neutral thermal conditions

What influences lifting capacity in practice

Holding efficiency impacted by specific conditions, mainly (from most important):

Air gap (between the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
Direction of force – maximum parameter is available only during perpendicular pulling. The force required to slide of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
Material type – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate lowers the load capacity.

Precautions when working with NdFeB magnets

Power loss in heat

Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.

Nickel allergy

A percentage of the population experience a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Prolonged contact might lead to dermatitis. We suggest use safety gloves.

Crushing force

Mind your fingers. Two powerful magnets will snap together instantly with a force of massive weight, crushing anything in their path. Be careful!

Machining danger

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

Pacemakers

Warning for patients: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.

Safe operation

Use magnets consciously. Their huge power can surprise even experienced users. Plan your moves and do not underestimate their force.

Keep away from computers

Equipment safety: Neodymium magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).

Keep away from children

These products are not toys. Swallowing multiple magnets may result in them pinching intestinal walls, which poses a critical condition and requires immediate surgery.

Material brittleness

Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.

Impact on smartphones

Navigation devices and smartphones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
