Magnetic force weakens drastically per each millimeter of gap. Note that even a microscopic distance (e.g., dirt, varnish, rust) noticeably weakens the grip. Magnetic products operate optimally at the point of direct contact; gap kills the force. Observe how flashily the pull force plummet, when the magnet does not touch flatly to the steel surface. When calculating the mounting, avoid additional spacers.

The following data shows the approximate shear load required to start the downward movement of the magnet downwards on a upright metal surface (considering typical friction coefficient). The holding force is relative to the gap size between the magnet and the surface.

Table 3: Wall mounting (shearing) - vertical pull
MPL 10x10x4 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.93 kg / 2.05 lbs 930.0 g / 9.1 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.62 kg / 1.37 lbs 620.0 g / 6.1 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.31 kg / 0.68 lbs 310.0 g / 3.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.55 kg / 3.42 lbs 1550.0 g / 15.2 N

When mounting a element on a upright plane (e.g., a car body), it you can count on only approx. 20%-30% of its maximum pull force. Gravity and a weak degree of grip cause that holders slide down faster than they pull off. Designing a wall mount? Note that the shear force is noticeably lower than the perpendicular breakaway force. On a smooth steel, the holder will slip down under a noticeably lighter load. Utilizing a rubberized layer can significantly increase the grip.

Table 4: Steel thickness (saturation) - sheet metal selection
MPL 10x10x4 / N38

Steel thickness (mm)	% power	Real pull force (kg/lbs/g/N)
0.5 mm	10%	0.31 kg / 0.68 lbs 310.0 g / 3.0 N
1 mm	25%	0.78 kg / 1.71 lbs 775.0 g / 7.6 N
2 mm	50%	1.55 kg / 3.42 lbs 1550.0 g / 15.2 N
3 mm	75%	2.33 kg / 5.13 lbs 2325.0 g / 22.8 N
5 mm	100%	3.10 kg / 6.83 lbs 3100.0 g / 30.4 N
10 mm	100%	3.10 kg / 6.83 lbs 3100.0 g / 30.4 N
11 mm	100%	3.10 kg / 6.83 lbs 3100.0 g / 30.4 N
12 mm	100%	3.10 kg / 6.83 lbs 3100.0 g / 30.4 N

A thin metal plate is not enough to absorb the entire magnetic field, which weakens actual performance of the holder. If you install a neodymium to a too thin substrate, the magnetism will penetrate right through and the pull force will drop sharply. To achieve 100% of this magnet's potential, you need a suitably thick element of metal. The material oversaturation causes that on sheet metal structures (e.g., car bodies), the magnet works worse. We advise picking the steel cross-section based on the following data.

Ordinary NdFeB products change their properties strength above the temperature limit. Avoid high temperatures – heat can permanently destroy this magnet. As the temperature rises, the magnet's force momentarily decreases. Avoid using this product close to heaters higher than its operating temperature limit. Too high temperature will cause permanent loss of magnetic properties.

*Engineering note: Heat tolerance is determined by both grade, as well as the dimension ratios. Low-profile magnets (pancake types) are more susceptible to demagnetization at lower temperatures compared to rod magnets. Red status in the table signals permanent field degradation for this particular item.

Two magnetic products attract each other from a wider radius than a magnet and steel setup. The connection of magnet-to-magnet creates a more powerful interaction and a further horizon of operation. Want to build a powerful holder? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when bringing together two magnets, the collision energy is massive. The levitation is a bit weaker than the connection force, but still impressive.
*The magnetic induction in repulsion mode reaches ~0 Gs at the geometric center of the gap (caused by magnetic field nullification).
Important: Calculations demonstrate sliding force of a pair of identical magnets (friction coefficient ~0.15 for Ni-Ni coating).

Powerful magnet radiation is a real danger to electronic devices as well as medical implants. These neodymiums generate a flux that prevents correct functioning of sensitive medical devices. Notice: the unseen radiation acts through matter and plastic. Special caution must be exercised by people with hearing aids and insulin pumps. Also at risk are: automatic timepieces, car keys, speakers, and screens. Do not bring the product near payment cards, HDD media, or sensitive navigation tools.

Magnetic elements are very brittle – a violent impact against metal can result in shattering. Control the attraction moment – a magnet released freely becomes dangerous. Striking energy can trigger coating fragments or painful pinches to skin. Be sure to control the product during bringing near metal so it doesn't hit violently against the steel surface. A collision at high speed ends with a crack 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. Wall mount (shear)

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

2. Steel saturation

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

3. Heat tolerance

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

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.46

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.

SMZR 25x225 / N52 - magnetic separator with handle

615.00 ZŁ brutto / pcs

Component MPL 10x10x4 / N38 features a low profile and industrial pulling force, making it a perfect solution for building separators and machines. This magnetic block with a force of 30.39 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.

The key to success is shifting 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 3.10 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. 3.10 kg), they are ideal as closers in furniture making and mounting elements in automation. 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. 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 clean and degrease 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.

The presented product is a neodymium magnet with precisely defined parameters: 10 mm (length), 10 mm (width), and 4 mm (thickness). It is a magnetic block with dimensions 10x10x4 mm and a self-weight of 3 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Pros and cons of Nd₂Fe₁₄B magnets.

Advantages

Apart from their notable power, neodymium magnets have these key benefits:

They do not lose power, even during nearly ten years – the drop in strength is only ~1% (based on measurements),
They are extremely resistant to demagnetization induced by external magnetic fields,
By covering with a lustrous coating of silver, the element has an professional look,
Magnetic induction on the working part of the magnet remains exceptional,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
Thanks to the possibility of precise forming and adaptation to custom needs, magnetic components can be modeled in a broad palette of forms and dimensions, which increases their versatility,
Wide application in electronics industry – they find application in hard drives, motor assemblies, diagnostic systems, and modern systems.
Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,

Weaknesses

What to avoid - cons of neodymium magnets: application proposals

They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
We suggest cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated forms.
Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these products are able to disrupt the diagnostic process medical when they are in the body.
Due to neodymium price, their price exceeds standard values,

Lifting parameters

Maximum magnetic pulling force – what affects it?

The lifting capacity listed is a measurement result conducted under the following configuration:

with the application of a yoke made of special test steel, ensuring maximum field concentration
possessing a thickness of at least 10 mm to ensure full flux closure
with an polished touching surface
with total lack of distance (without paint)
for force acting at a right angle (in the magnet axis)
at standard ambient temperature

Practical aspects of lifting capacity – factors

Please note that the working load may be lower influenced by the following factors, starting with the most relevant:

Distance (between the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
Steel thickness – insufficiently thick sheet does not accept the full field, causing part of the flux to be escaped to the other side.
Material type – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
Smoothness – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate lowers the lifting capacity.

Warnings

Beware of splinters

NdFeB magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets will cause them cracking into shards.

Medical interference

Patients with a heart stimulator should keep an safe separation from magnets. The magnetism can interfere with the functioning of the life-saving device.

Precision electronics

Note: neodymium magnets generate a field that disrupts sensitive sensors. Maintain a separation from your phone, device, and GPS.

Physical harm

Big blocks can break fingers in a fraction of a second. Do not put your hand between two strong magnets.

Danger to the youngest

Only for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Keep out of reach of kids and pets.

Safe operation

Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.

Electronic devices

Avoid bringing magnets close to a purse, computer, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.

Fire risk

Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.

Operating temperature

Avoid heat. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).

Allergic reactions

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation occurs, cease working with magnets and wear gloves.
