💡 Check why professionals choose Dhit over cheap substitutes
Instead of believing fairy tales on YouTube with tests on uncertified equipment, see what really determines your magnet's power:
- 📏 Magnet thickness in the casing (min. 10mm) – This is what matters most! Thin magnets are weak. Thanks to the 1cm thickness of N52 neodymium, your magnet "sees" metal even through thick rust and mud.
- 🛡️ Armored protection (Black Epoxy) – Forget about rust. This coating doesn't chip when hitting rocks and protects the magnet in water much better than regular nickel, which fails quickly.
- 🧲 Eyelets that don't steal power – Made of special non-magnetic steel, so they don't stick to the magnet and don't block the force. Important: mount only one eyelet at a time! Using 3 at once is a mistake that weakens the magnet.
- 🧶 Certified rope (min. 8mm) – You gain the certainty that your gear won't stay at the bottom. It's thick and comfortable, so it doesn't cut your fingers when pulling out heavy scrap metal.
- 🚀 Our advantage: We are the only ones combining the strongest N52 neodymium (10mm thick) with non-magnetic eyelets. This is real power and durability you won't find anywhere else.
Invest in solid equipment and enjoy the results!

Pros as well as cons of neodymium magnets.
Strengths
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
- Neodymium magnets prove to be exceptionally resistant to loss of magnetic properties caused by external magnetic fields,
- By covering with a shiny coating of silver, the element presents an nice look,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the option of free shaping and adaptation to custom solutions, magnetic components can be created in a wide range of shapes and sizes, which amplifies use scope,
- Wide application in electronics industry – they find application in data components, brushless drives, medical devices, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which allows their use in miniature devices
Limitations
- At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength 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 start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of making nuts in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
- Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, small components of these products can complicate diagnosis 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
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- using a sheet made of low-carbon steel, serving as a ideal flux conductor
- whose transverse dimension is min. 10 mm
- with an ideally smooth touching surface
- with direct contact (no impurities)
- during pulling in a direction perpendicular to the plane
- at temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Air gap (between the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, rust or debris).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel attracts best. Higher carbon content lower magnetic properties and lifting capacity.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Thermal environment – heating the magnet results in weakening of force. Check the thermal limit for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under parallel forces the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Fragile material
Beware of splinters. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.
Keep away from computers
Do not bring magnets close to a wallet, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.
Maximum temperature
Regular neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.
Compass and GPS
Remember: neodymium magnets generate a field that disrupts sensitive sensors. Maintain a separation from your mobile, device, and navigation systems.
Health Danger
For implant holders: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
Bodily injuries
Pinching hazard: The attraction force is so immense that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.
Swallowing risk
Strictly store magnets out of reach of children. Ingestion danger is significant, and the effects of magnets connecting inside the body are life-threatening.
Sensitization to coating
Medical facts indicate that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, refrain from direct skin contact and choose encased magnets.
Fire warning
Powder generated during machining of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Conscious usage
Use magnets consciously. Their powerful strength can surprise even experienced users. Plan your moves and respect their force.
