Grip strength weakens significantly with every subsequent millimeter of spacing. Keep in mind that every additional insulation layer (e.g., dirt, varnish, rust) noticeably weakens the grip. Magnetic products work optimally at the point of direct contact; distance kills the force. See how rapidly the parameters plummet, when the magnet does not adhere flatly to the steel surface. When calculating the assembly, eliminate additional spacers.

This section calculates the estimated shear load required to initiate the downward movement of the magnet vertically on a vertical metal surface (assuming standard friction coefficient). This value is relative to the separation distance between the magnet and the metal.

Table 3: Wall mounting (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 hanging a magnet on a vertical plane (e.g., a board), it will maintain barely about 1/5 of its nominal power. Gravitational force and a weak degree of grip cause that holders move down easier than they detach. Want to create a vertical fastening? Remember that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the magnet will slide down under a much lighter weight. Application of an anti-slip coating can significantly increase the grip.

A thin sheet is not enough to take in the entire magnetic field, which weakens actual performance of the magnet. If you install a neodymium to a weak sheet, the magnetism will penetrate right through and the holding will be smaller. To achieve the maximum of this magnet's power, you need a suitably thick element of steel. The saturation phenomenon means that on delicate walls (e.g., car bodies), the holder works worse. We suggest choosing the steel thickness from these parameters.

Ordinary NdFeB products irreversibly lose strength above the temperature limit. Avoid high temperatures – heat can irreversibly demagnetize this product. With increasing heat, the magnet's force temporarily decreases. Do not use this product close to ovens exceeding its safe range. Too high temperature will result in destruction of magnetic properties.

*Important note: Temperature resistance is determined by both grade, and the Permeance Coefficient Pc. Thin magnets (pancake types) are more susceptible to demagnetization under lower heat stress than taller cylinders. Red status in the table signals a risk of irreversible loss for this specific geometry.

Two magnetic products interact from a significantly greater distance than a neodymium and metal combination. The connection of two magnets produces a massive flux and a wider radius of action. Want to build a powerful holder? Apply two magnets instead of one magnet and a steel. Be careful that when bringing together two magnets, the impact force is huge. The repulsion force is marginally weaker than the attraction, but still significant.
*The magnetic induction in repulsion mode is approximately ~0 Gs in the exact middle of the gap (caused by magnetic field nullification).
* Figures apply to friction force of a pair of matching neodymium magnets (friction ~0.15 for Ni-Ni coating).

Table 7: Hazards (electronics) - precautionary measures

Powerful magnet radiation is a large risk to IT equipment and pacemakers. These NdFeB products generate a flux that destroys function of sensitive medical devices. Remember: the invisible magnetic field passes through tissues and housings. Exceptional care must be exercised by people with hearing aids and drug dispensers. The risk also applies to: automatic timepieces, remotes, speakers, and displays. Do not place the magnet near cards, hard drives, or precise measuring instruments.

Table 8: Impact energy (cracking risk) - warning
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

Magnetic elements are very brittle – a violent impact against metal risks their cracking. Watch the impact speed – a neodymium left loose becomes dangerous. Kinetic force can destroy the magnet or painful pinches to skin. Hold the magnet firmly during mounting so it doesn't hit violently against the metal. A collision at high speed ends with a crack of the magnet. Use safety goggles when handling with powerful specimens.

Corrosion warning: 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. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

*Caution: On a vertical surface, the magnet retains just a fraction of its perpendicular strength.

2. Efficiency vs thickness

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

3. Power loss vs temp

*For N38 material, 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.

This product is a very powerful magnet in the shape of a plate made of NdFeB material, which, with dimensions of 50x30x4 mm and a weight of 45 g, guarantees premium class connection. This rectangular block with a force of 74.26 N is ready for shipment in 24h, allowing for rapid realization of your project. 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 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. Thanks to the flat surface and high force (approx. 7.57 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. Customers often choose this model for workshop organization 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. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Remember to clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

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. In practice, this means that this magnet has the greatest attraction force on its main planes (50x30 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 50x30x4 mm, which, at a weight of 45 g, makes it an element with high 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 protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of neodymium magnets.

Advantages

Besides their exceptional magnetic power, neodymium magnets offer the following advantages:

They retain full power for nearly ten years – the drop is just ~1% (according to analyses),
Neodymium magnets remain exceptionally resistant to demagnetization caused by external interference,
The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to look better,
Magnets have maximum magnetic induction on the active area,
Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
Thanks to flexibility in designing and the capacity to adapt to unusual requirements,
Key role in future technologies – they are commonly used in computer drives, drive modules, precision medical tools, and complex engineering applications.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Limitations

Disadvantages of neodymium magnets:

They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power 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
When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
Due to limitations in creating nuts and complicated shapes in magnets, we recommend using a housing - magnetic mechanism.
Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small components of these magnets can complicate diagnosis medical when they are in the body.
Due to neodymium price, their price is higher than average,

Pull force analysis

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

The specified lifting capacity refers to the limit force, obtained under laboratory conditions, specifically:

with the use of a sheet made of special test steel, guaranteeing full magnetic saturation
possessing a massiveness of at least 10 mm to avoid saturation
with a plane perfectly flat
without the slightest air gap between the magnet and steel
for force acting at a right angle (in the magnet axis)
at room temperature

Magnet lifting force in use – key factors

Real force impacted by specific conditions, including (from priority):

Gap (between the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
Base massiveness – insufficiently thick sheet does not accept the full field, causing part of the power to be lost to the other side.
Plate material – low-carbon steel gives the best results. Alloy steels decrease magnetic properties and lifting capacity.
Surface finish – full contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
Temperature influence – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity was measured by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.

Safety rules for work with neodymium magnets

Life threat

People with a ICD have to keep an absolute distance from magnets. The magnetism can disrupt the functioning of the implant.

Machining danger

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

Protective goggles

Neodymium magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets leads to them breaking into small pieces.

Heat sensitivity

Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. Damage is permanent.

Conscious usage

Handle magnets with awareness. Their huge power can surprise even experienced users. Stay alert and respect their force.

Skin irritation risks

Some people have a sensitization to nickel, which is the common plating for neodymium magnets. Prolonged contact can result in skin redness. We suggest use protective gloves.

Swallowing risk

Product intended for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep away from children and animals.

Bone fractures

Big blocks can break fingers instantly. Never put your hand between two attracting surfaces.

Data carriers

Very strong magnetic fields can erase data on payment cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
