Pulling power weakens drastically with every subsequent millimeter of distance. Note that even the smallest gap (e.g., dirt, varnish, rust) noticeably reduces the pull force. Magnetic products operate most effectively in perfect adhesion; gap kills the power. Observe how quickly the parameters fall, when the product does not adhere tightly to the metal substrate. When calculating the arrangement, avoid unnecessary gaps.

This section indicates the theoretical force sufficient to initiate the downward movement of the magnet downwards along a upright steel wall (assuming standard friction coefficient). This value varies with the distance between the magnet and the surface.

When hanging a magnet on a vertical surface (e.g., a fridge), it will only hold just approx. 20%-30% of its nominal power. Gravitational force and a low friction coefficient cause that magnets slip faster than they detach. Want to create a vertical fastening? Note that the sliding force is noticeably lower than the maximum static pull force. On a smooth steel, the element will give way down under a significantly smaller cargo. Application of an anti-slip coating can significantly improve the result.

A thin sheet is incapable of take in the full magnetic flux, which squanders power of the holder. Should you attach a powerful product to a thin surface, the flux will pass right through and the pull force will drop sharply. To utilize full efficiency of this magnet's power, you need a suitably thick piece of steel. The material oversaturation means that on thin elements (e.g., appliance housings), the holder holds weaker. We recommend selecting the steel dimension from these parameters.

Classic neodymiums irreversibly lose power after exceeding the maximum temperature. Avoid high temperatures – high temperature can permanently destroy this magnet. With increasing heat, the neodymium's force temporarily drops. Refrain from using this product near heat sources higher than its safe range. Too high temperature will result in irreversible degradation of magnetic properties.

*Engineering note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Flat magnets (pancake types) may lose charge permanently under lower heat stress compared to rod magnets. Warning indicator in the table points to a risk of irreversible loss for this specific geometry.

Two magnetic products attract each other from a wider radius than a magnet and sheet setup. Such a system of two magnets produces a massive flux and a wider radius of operation. Planning to create a strong closure? Utilize two neodymiums instead of a neodymium and a striker plate. Remember that when attracting two neodymiums, the pinch force is massive. The repulsion force is slightly lower than the connection force, but still significant.
*The magnetic induction between like poles reaches ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
Important: Calculations apply to shear force of two matching magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field poses a large risk to electronics as well as medical implants. These NdFeB products generate a flux that disrupts operation of digital equipment. Be aware: the unseen radiation acts through matter and glass. Increased vigilance must be exercised by people with hearing aids and drug dispensers. Also at risk are: mechanical watches, car keys, membranes, and screens. Avoid contact with magnetic cards, HDD media, or sensitive navigation tools.

Table 8: Dynamics (cracking risk) - collision effects

50 mm	32.20 km/h (8.94 m/s)	23.99 J
100 mm	45.13 km/h (12.54 m/s)	47.14 J

NdFeB products are delicate – a strong collision with metal risks their cracking. Control the attraction moment – a magnet released freely speeds with massive force. Striking energy can destroy the magnet or injury to skin. Hold the magnet firmly during mounting so it doesn't hit with great force against the steel surface. A collision at high speed almost guarantees destruction of the neodymium. Use safety goggles when working 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!

In water, the magnet feels stronger thanks to Archimedes' principle. However, remember the water resistance when pulling the rope quickly.

1. Shear force

*Caution: On a vertical surface, the magnet holds merely approx. 20-30% of its max power.

2. Steel saturation

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

3. Temperature resistance

*For N38 material, the max working temp 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.

Component MPL 100x40x20 / N38 features a low profile and professional pulling force, making it an ideal solution for building separators and machines. As a block magnet with high power (approx. 120.01 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 100x40x20 / 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. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

Plate magnets MPL 100x40x20 / N38 are the foundation for many industrial devices, such as magnetic separators and linear motors. They work great as fasteners 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.

For mounting flat magnets MPL 100x40x20 / N38, it is best to use strong epoxy glues (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Remember to roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 100x40x20 / N38 model is magnetized through the thickness (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.

This model is characterized by dimensions 100x40x20 mm, which, at a weight of 600 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 100x40x20 mm and a self-weight of 600 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Advantages as well as disadvantages of Nd₂Fe₁₄B magnets.

Advantages

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

Their power is durable, and after approximately 10 years it drops only by ~1% (according to research),
They possess excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to look better,
Magnets are distinguished by extremely high magnetic induction on the outer side,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Possibility of custom modeling as well as modifying to concrete applications,
Key role in electronics industry – they are commonly used in hard drives, electric motors, advanced medical instruments, also other advanced devices.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Disadvantages of NdFeB magnets:

Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
We suggest cover - magnetic holder, due to difficulties in creating threads inside the magnet and complicated forms.
Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Furthermore, small components of these magnets can be problematic in diagnostics medical in case of swallowing.
With budget limitations the cost of neodymium magnets is economically unviable,

Pull force analysis

Best holding force of the magnet in ideal parameters – what it depends on?

Holding force of 120.01 kg is a result of laboratory testing executed under the following configuration:

on a block made of mild steel, perfectly concentrating the magnetic field
possessing a thickness of minimum 10 mm to avoid saturation
with an ideally smooth contact surface
with direct contact (no paint)
for force applied at a right angle (pull-off, not shear)
at standard ambient temperature

Key elements affecting lifting force

Holding efficiency is affected by working environment parameters, such as (from priority):

Air gap (between the magnet and the metal), as even a microscopic clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
Steel thickness – too thin steel causes magnetic saturation, causing part of the flux to be wasted into the air.
Material composition – different alloys reacts the same. Alloy additives worsen the attraction effect.
Plate texture – ground elements ensure maximum contact, which increases force. Uneven metal reduce efficiency.
Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet and the plate decreases the holding force.

H&S for magnets

Immense force

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

Thermal limits

Do not overheat. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, look for HT versions (H, SH, UH).

Beware of splinters

Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Fire risk

Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Safe distance

Powerful magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.

Magnetic interference

GPS units and mobile phones are highly susceptible to magnetism. Direct contact with a strong magnet can ruin the sensors in your phone.

Pacemakers

Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.

Finger safety

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

Skin irritation risks

Studies show that the nickel plating (the usual finish) is a common allergen. If your skin reacts to metals, prevent touching magnets with bare hands and opt for encased magnets.

This is not a toy

NdFeB magnets are not toys. Eating several magnets may result in them attracting across intestines, which poses a critical condition and requires urgent medical intervention.
