Pulling power weakens drastically per each millimeter of distance. Keep in mind that even a very thin break (e.g., dirt, paint, dust) significantly reduces the pull force. Magnetic products work most effectively at the point of direct contact; gap weakens the force. Observe how quickly the load capacity fall, when the magnet does not touch flatly to the steel surface. When designing the arrangement, discard redundant distances.

The table below presents the estimated holding capacity sufficient to initiate the slippage of the magnet vertically on a upright metal surface (considering standard friction coefficient). This parameter depends on the air gap between the magnet and the metal.

Table 3: Vertical assembly (shearing) - behavior on slippery surfaces
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 magnet on a vertical surface (e.g., a fridge), it will only hold just approx. 20%-30% of nominal attraction strength. Gravity as well as a weak degree of grip influence the fact that magnets slide down easier than they detach. Want to create a vertical fastening? Note that the sliding force is much weaker than the maximum static pull force. On a slippery surface, the element will slide down under a much lighter weight. Utilizing a rubberized layer can significantly increase the grip.

A thin sheet is unable to conduct the entire magnetic field, which squanders power of the holder. Should you attach a powerful product to a thin surface, the magnetism will pass right through and the pull force will drop sharply. To utilize full efficiency of this neodymium's potential, you need a suitably thick backing of steel. The material oversaturation causes that on sheet metal structures (e.g., car bodies), the holder shows lower pull force. We suggest choosing the steel cross-section based on the following data.

Standard neodymium magnets irreversibly lose power past the thermal threshold. Protect against heat – heat can irreversibly damage this magnet. With every degree above norm, the magnet's power briefly lowers. Avoid using this magnet in hot environments exceeding its safe range. Too high temperature will lead to irreversible degradation of magnetism.

*Engineering 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 at lower temperatures than taller cylinders. The danger warning in the table signals a risk of irreversible loss for this particular item.

Two magnetic products interact from a significantly greater distance than a neodymium and metal setup. The connection of magnet-to-magnet produces a massive flux and a further horizon of operation. Want to build a powerful holder? Use a pair of magnets instead of a neodymium and a steel. Exercise caution that when bringing together two magnets, the impact force is extreme. The repulsion force is slightly lower than the connection force, but still large.
*The magnetic induction between like poles drops to ~0 Gs in the exact middle between the magnets (due to field cancellation).
Important: Calculations refer to shear force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field poses a large risk to electronic devices as well as medical implants. These magnets produce a field that destroys function of sensitive medical devices. Be aware: the unseen radiation passes through tissues and plastic. Increased vigilance must be exercised by people with hearing aids and insulin pumps. Influence will be felt by: mechanical watches, car keys, membranes, and displays. Avoid contact with magnetic cards, HDD media, or precise measuring instruments.

Magnetic elements are very brittle – a strong collision with metal can result in shattering. Pay attention to connection velocity – a magnet released freely turns into a projectile. Kinetic force can cause material chips or dangerous crushing to fingers. Be sure to control the product during mounting so it doesn't hit violently against the steel surface. A contact at a velocity of dozens of km/h ends with a crack of the neodymium. Wear safety glasses when playing with powerful specimens.

Rust risk: Remember to wipe the magnet thoroughly after removing it from water and apply a protective layer (e.g., oil) to avoid corrosion.

Water displaces steel, making heavy objects slightly lighter. However, remember the water resistance when pulling the rope quickly.

1. Wall mount (shear)

*Note: On a vertical wall, the magnet holds just ~20% of its nominal pull.

2. Steel thickness impact

*Thin steel (e.g. computer case) severely weakens the holding force.

3. Temperature resistance

*For standard magnets, the safety limit 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.

602.70 ZŁ brutto / pcs

Model MPL 50x30x4 / N38 features a flat shape and professional pulling force, making it a perfect solution for building separators and machines. This magnetic block with a force of 74.26 N is ready for shipment in 24h, allowing for rapid realization of your project. 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. 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.

They constitute a key element in the production of generators and material handling systems. 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.

For mounting flat magnets MPL 50x30x4 / N38, it is best to use two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Remember to roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

The magnetic axis runs through the shortest dimension, which is typical for gripper magnets. 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. The key parameter here is the holding force amounting to approximately 7.57 kg (force ~74.26 N), which, with such a flat shape, proves the high grade of the material. The product meets the standards for N38 grade magnets.

Advantages as well as disadvantages of rare earth magnets.

Benefits

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

They have stable power, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
Magnets very well protect themselves against loss of magnetization caused by external fields,
A magnet with a shiny nickel surface has better aesthetics,
Magnetic induction on the working layer of the magnet is extremely intense,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures approaching 230°C and above...
Possibility of custom creating as well as modifying to individual requirements,
Wide application in electronics industry – they are utilized in mass storage devices, drive modules, diagnostic systems, also modern systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in small systems

Limitations

Drawbacks and weaknesses of neodymium magnets and ways of using them

At 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.
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
We suggest cover - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex shapes.
Health risk resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small elements of these products are able to be problematic in diagnostics medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Pull force analysis

Maximum lifting capacity of the magnet – what affects it?

The load parameter shown refers to the peak performance, obtained under laboratory conditions, meaning:

with the use of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
possessing a thickness of minimum 10 mm to ensure full flux closure
with an ground touching surface
under conditions of no distance (metal-to-metal)
for force applied at a right angle (pull-off, not shear)
at room temperature

Key elements affecting lifting force

In real-world applications, the real power depends on a number of factors, presented from most significant:

Distance – the presence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
Direction of force – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
Material composition – different alloys attracts identically. High carbon content weaken the attraction effect.
Surface finish – full contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
Temperature influence – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.

Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, however under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.

Safe handling of NdFeB magnets

Medical interference

Life threat: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.

Magnet fragility

NdFeB magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets will cause them breaking into small pieces.

Magnetic media

Avoid bringing magnets close to a purse, computer, or TV. The magnetism can destroy these devices and erase data from cards.

Choking Hazard

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

Pinching danger

Big blocks can break fingers in a fraction of a second. Under no circumstances place your hand between two strong magnets.

Combustion hazard

Powder generated during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.

Avoid contact if allergic

Some people suffer from a sensitization to nickel, which is the typical protective layer for neodymium magnets. Extended handling may cause skin redness. It is best to use safety gloves.

Do not overheat magnets

Watch the temperature. Heating the magnet to high heat will ruin its magnetic structure and pulling force.

Impact on smartphones

Navigation devices and smartphones are highly sensitive to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.

Do not underestimate power

Handle magnets consciously. Their huge power can surprise even professionals. Stay alert and do not underestimate their power.
