Pulling power weakens significantly per each millimeter of spacing. Remember that even a microscopic distance (e.g., dirt, varnish, dust) strongly reduces the pull force. Magnetic products operate strongest during direct contact; distance weakens the force. Analyze how quickly the pull force fall, when the magnet does not adhere directly to the steel surface. When planning the arrangement, avoid unnecessary gaps.

This section indicates the theoretical shear load needed to initiate the shifting of the magnet vertically on a upright steel plate (considering typical friction coefficient). This value varies with the air gap between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 50x30x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.27 kg / 5.01 lbs 2271.0 g / 22.3 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.51 kg / 3.34 lbs 1514.0 g / 14.9 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.76 kg / 1.67 lbs 757.0 g / 7.4 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.79 kg / 8.34 lbs 3785.0 g / 37.1 N

When placing a element on a upright plane (e.g., a fridge), it will maintain barely about 20%-30% of its nominal power. Gravitational force as well as a weak degree of grip cause that magnets slip easier than they detach. Planning a hanger? Remember that the sliding force is significantly lower than the maximum static pull force. On a slippery surface, the element will slip down under a noticeably lighter weight. Application of an anti-slip coating can drastically increase the grip.

A thin sheet is not enough to take in the full magnetic flux, which squanders power of the magnet. If you attach a powerful product to a weak sheet, the flux will penetrate right through and the pull force will drop sharply. To utilize full efficiency of this magnet's power, you require a sufficiently solid piece of metal. The saturation effect causes that on thin elements (e.g., thin profiles), the magnet works worse. We suggest choosing the steel cross-section based on the following data.

Standard neodymium magnets change their properties strength past the thermal threshold. Watch out for overheating – heat can irreversibly destroy this magnet. With every degree above norm, the magnet's power briefly decreases. Avoid using this product in hot environments higher than its working range. Too high temperature will result in destruction of magnetic properties.

*Engineering note: Heat tolerance is determined by both grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) are more susceptible to demagnetization at lower temperatures than long magnets. Warning indicator in the table indicates a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a significantly greater distance than a magnet and steel setup. The setup of two magnets creates a more powerful interaction and a further horizon of operation. Want to build a strong closure? Utilize two neodymiums instead of one magnet and a steel. Exercise caution that when connecting a pair of magnets, the impact force is huge. The repulsion force is marginally weaker than the attraction, but still significant.
*Flux density for N-N configuration is approximately ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
* Estimates apply to shear force of a pair of same neodymium magnets (friction coefficient ~0.15 for Ni-Ni coating).

Table 7: Protective zones (electronics) - warnings

A strong magnetic field poses a large risk to electronic devices and pacemakers. These magnets produce a flux that prevents correct functioning of sensitive medical devices. Remember: the unseen radiation penetrates the body and housings. Exceptional care must be exercised by people with cochlear implants and insulin pumps. The risk also applies to: automatic timepieces, car keys, membranes, and displays. Do not bring the product near payment cards, hard drives, or precise measuring instruments.

Table 8: Dynamics (kinetic energy) - collision effects
MPL 50x30x4 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	15.99 km/h (4.44 m/s)	0.44 J
30 mm	23.02 km/h (6.39 m/s)	0.92 J
50 mm	29.30 km/h (8.14 m/s)	1.49 J
100 mm	41.37 km/h (11.49 m/s)	2.97 J

NdFeB products are delicate – a collision with steel causes immediate chipping. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Striking energy can destroy the magnet or injury to fingers. Always hold the magnet during bringing near metal so it doesn't slam with momentum against the metal. A collision at high speed ends with a crack of the magnet. Wear safety glasses when working with powerful specimens.

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

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Note: On a vertical wall, the magnet holds only ~20% of its max power.

2. Steel thickness impact

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

3. Heat tolerance

*For standard magnets, 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) = 0.14

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 an extremely strong plate magnet made of NdFeB material, which, with dimensions of 50x30x4 mm and a weight of 45 g, guarantees premium class connection. As a magnetic bar with high power (approx. 7.57 kg), this product is available immediately from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

Separating strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. Watch your fingers! Magnets with a force of 7.57 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 50x30x4 / 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. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 50x30x4 / N38, we recommend utilizing 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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 50x30x4 / N38 model is magnetized through the thickness (dimension 4 mm), which means that the N and S poles are located on its largest, flat surfaces. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 50x30x4 mm, which, at a weight of 45 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 50x30x4 mm and a self-weight of 45 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Advantages and disadvantages of rare earth magnets.

Advantages

Besides their high retention, neodymium magnets are valued for these benefits:

They retain attractive force for around 10 years – the loss is just ~1% (based on simulations),
Magnets very well protect themselves against demagnetization caused by external fields,
In other words, due to the smooth layer of gold, the element is aesthetically pleasing,
They are known for high magnetic induction at the operating surface, making them more effective,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Possibility of custom machining as well as optimizing to concrete conditions,
Wide application in electronics industry – they serve a role in data components, electric motors, diagnostic systems, also technologically advanced constructions.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

What to avoid - cons of neodymium magnets and ways of using them

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as 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 start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
We suggest a housing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated forms.
Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the context of child safety. Additionally, small components of these magnets 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 increases costs of application in large quantities

Pull force analysis

Breakaway strength of the magnet in ideal conditions – what it depends on?

The lifting capacity listed is a measurement result executed under specific, ideal conditions:

on a block made of mild steel, optimally conducting the magnetic flux
whose transverse dimension is min. 10 mm
with a surface perfectly flat
with zero gap (without paint)
for force acting at a right angle (in the magnet axis)
at standard ambient temperature

Determinants of practical lifting force of a magnet

It is worth knowing that the magnet holding will differ subject to the following factors, in order of importance:

Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
Direction of force – maximum parameter is available only during perpendicular pulling. The force required to slide of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
Base massiveness – too thin plate does not close the flux, causing part of the power to be wasted into the air.
Material composition – not every steel reacts the same. Alloy additives worsen the attraction effect.
Surface finish – full contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
Thermal factor – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate reduces the load capacity.

H&S for magnets

Do not give to children

Adult use only. Small elements pose a choking risk, causing intestinal necrosis. Store out of reach of kids and pets.

Nickel allergy

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation occurs, immediately stop working with magnets and wear gloves.

Bodily injuries

Protect your hands. Two large magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!

Medical interference

Warning for patients: Powerful magnets disrupt medical devices. Maintain at least 30 cm distance or request help to work with the magnets.

Safe distance

Equipment safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, medical aids, timepieces).

Machining danger

Powder produced during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Magnets are brittle

Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. Wear goggles.

Immense force

Use magnets with awareness. Their powerful strength can surprise even experienced users. Stay alert and respect their force.

Keep away from electronics

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

Permanent damage

Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.
