Technical analysis of the product - technical parameters

Presented information are the result of a mathematical analysis. Results rely on algorithms for the class NdFeB. Operational conditions might slightly differ. Please consider these calculations as a preliminary roadmap for designers.

Table 1: Static force (force vs gap) - power drop
MPL 60x10x5 / N38

Distance (mm)	Induction (Gauss) / mT	Pull Force (kg)	Risk Status

10 mm	598 Gs 59.8 mT	0.44 kg / 440.9 g 4.3 N	weak grip
15 mm	330 Gs 33.0 mT	0.13 kg / 134.3 g 1.3 N	weak grip
20 mm	205 Gs 20.5 mT	0.05 kg / 51.9 g 0.5 N	weak grip
30 mm	96 Gs 9.6 mT	0.01 kg / 11.4 g 0.1 N	weak grip
50 mm	31 Gs 3.1 mT	0.00 kg / 1.2 g 0.0 N	weak grip

Grip strength weakens drastically with every subsequent millimeter of distance. Remember that every additional insulation layer (e.g., dirt, paint, veneer) noticeably weakens the grip. Neodymiums operate strongest at the point of direct contact; distance kills the power. Observe how flashily the load capacity plummet, when the magnet does not adhere flatly to the steel surface. When calculating the arrangement, eliminate additional spacers.

Table 2: Vertical assembly (sliding) - vertical pull
MPL 60x10x5 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg)
Raw steel	µ = 0.3 30% Nominalnej Siły	6.70 kg / 6696.0 g 65.7 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	4.46 kg / 4464.0 g 43.8 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	2.23 kg / 2232.0 g 21.9 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	11.16 kg / 11160.0 g 109.5 N

When placing a magnet on a upright plane (e.g., a fridge), it will only hold barely about 1/5 of its maximum pull force. Gravitational force as well as a low friction coefficient influence the fact that products slip faster than they pull off. Want to create a vertical fastening? Note that the shear force is noticeably lower than the maximum static pull force. On a painted metal, the holder will give way down under a much lighter load. Using a rubber coating can significantly increase the grip.

Table 3: Steel thickness (substrate influence) - sheet metal selection
MPL 60x10x5 / N38

Steel thickness (mm)	% power	Real pull force (kg)
0.5 mm	5%	1.12 kg / 1116.0 g 10.9 N
1 mm	13%	2.79 kg / 2790.0 g 27.4 N
2 mm	25%	5.58 kg / 5580.0 g 54.7 N
5 mm	63%	13.95 kg / 13950.0 g 136.8 N
10 mm	100%	22.32 kg / 22320.0 g 219.0 N

A thin sheet is not enough to absorb the entire magnetic field, which weakens actual performance of the magnet. Should you install a neodymium to a too thin substrate, the flux will penetrate right through and the pull force will drop sharply. To achieve full efficiency of this neodymium's potential, you need a suitably thick piece of steel. The saturation phenomenon causes that on sheet metal structures (e.g., appliance housings), the magnet shows lower pull force. We recommend selecting the steel cross-section from these parameters.

Table 4: Thermal resistance (material behavior) - thermal limit
MPL 60x10x5 / N38

100 °C	-28.8%	15.89 kg / 15891.8 g 155.9 N

Classic neodymiums irreversibly lose strength past the thermal threshold. Watch out for overheating – heat can permanently demagnetize this product. As the temperature rises, the magnet's force briefly lowers. Avoid using this product close to heaters higher than its safe range. Too high temperature will result in destruction of magnetism.

Two magnetic products attract each other from a significantly greater distance than a magnet and sheet combination. The connection of magnet-to-magnet creates a more powerful interaction and a further horizon of action. Designing a powerful holder? Utilize two neodymiums instead of a neodymium and a steel. Exercise caution that when connecting a pair of magnets, the collision energy is extreme. The levitation is marginally weaker than the attraction, but still large.

Powerful magnet radiation is a serious hazard to electronic devices and medical implants. These neodymiums produce a flux that disrupts operation of digital equipment. Be aware: the invisible magnetic field passes through tissues and housings. Exceptional care must be exercised by people with cochlear implants and drug dispensers. Also at risk are: mechanical watches, car keys, speakers, and screens. Do not bring the product near payment cards, hard drives, or sensitive navigation tools.

Table 7: Impact energy (kinetic energy) - collision effects
MPL 60x10x5 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	32.15 km/h (8.93 m/s)	0.90 J
30 mm	55.03 km/h (15.29 m/s)	2.63 J
50 mm	71.03 km/h (19.73 m/s)	4.38 J
100 mm	100.45 km/h (27.90 m/s)	8.76 J

Neodymium magnets are prone to chipping – a strong collision with metal risks their cracking. Pay attention to connection velocity – a magnet released freely becomes dangerous. Kinetic force can trigger coating fragments or dangerous crushing to skin. Hold the magnet firmly during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Wear safety glasses when playing with large magnets.

Neodymium magnets are highly susceptible to corrosion without proper protection. Moisture resistance is crucial for installations in bathrooms or outdoors.

Table 9: Underwater work (magnet fishing)

Environment	Effective steel pull	Effect
Air (land)	22.32 kg	Standard

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

Contrary to myths, water does not block the magnetic field. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

Model MPL 60x10x5 / N38 features a low profile and industrial pulling force, making it a perfect solution for building separators and machines. As a block magnet with high power (approx. 22.32 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 22.32 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 60x10x5 / 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 workshop organization on strips and for advanced DIY and modeling projects, where precision and power count.

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.

Standardly, the MPL 60x10x5 / N38 model is magnetized axially (dimension 5 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 (60x10 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 60x10x5 mm, which, at a weight of 22.5 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 60x10x5 mm and a self-weight of 22.5 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.

Besides their tremendous pulling force, neodymium magnets offer the following advantages:

They do not lose magnetism, even during around 10 years – the reduction in lifting capacity is only ~1% (based on measurements),
Magnets perfectly resist against loss of magnetization caused by ambient magnetic noise,
By using a lustrous coating of silver, the element has an professional look,
Neodymium magnets create maximum magnetic induction on a small area, which allows for strong attraction,
Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
Thanks to modularity in shaping and the capacity to customize to individual projects,
Wide application in innovative solutions – they are commonly used in mass storage devices, electric drive systems, advanced medical instruments, also multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in small systems

Disadvantages of neodymium magnets:

To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
Neodymium 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 extremely resistant to heat
Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in realizing threads and complex shapes in magnets, we propose using cover - magnetic mechanism.
Possible danger related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these devices can complicate diagnosis medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Detachment force of the magnet in optimal conditions – what contributes to it?

The force parameter is a measurement result executed under specific, ideal conditions:

with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
possessing a thickness of minimum 10 mm to ensure full flux closure
characterized by lack of roughness
without the slightest clearance between the magnet and steel
under vertical force direction (90-degree angle)
in temp. approx. 20°C

Practical aspects of lifting capacity – factors

Real force impacted by working environment parameters, including (from priority):

Air gap (betwixt the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, corrosion or dirt).
Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
Material type – the best choice is pure iron steel. Hardened steels may have worse magnetic properties.
Plate texture – ground elements guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.

* Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast 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 decreases the holding force.

Warnings

Eye protection

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

Do not underestimate power

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

Safe distance

Very strong magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.

Skin irritation risks

Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, avoid direct skin contact and opt for encased magnets.

Mechanical processing

Fire hazard: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.

Swallowing risk

Absolutely store magnets away from children. Choking hazard is high, and the consequences of magnets clamping inside the body are very dangerous.

Medical implants

Medical warning: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.

Magnetic interference

A strong magnetic field interferes with the functioning of compasses in smartphones and GPS navigation. Keep magnets close to a device to prevent breaking the sensors.

Crushing force

Protect your hands. Two powerful magnets will snap together immediately with a force of massive weight, crushing everything in their path. Exercise extreme caution!

Do not overheat magnets

Keep cool. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
