💡 Check why professionals choose Dhit over cheap substitutes
Don't be fooled by amateur online tests – go for certified quality and specific parameters that guarantee success:
- 📏 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!

Other offers
Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- Their magnetic field is durable, and after around ten years it decreases only by ~1% (according to research),
- They show high resistance to demagnetization induced by external disturbances,
- In other words, due to the smooth layer of silver, the element looks attractive,
- They feature high magnetic induction at the operating surface, which affects their effectiveness,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the potential of flexible shaping and adaptation to unique needs, NdFeB magnets can be manufactured in a wide range of geometric configurations, which amplifies use scope,
- Universal use in electronics industry – they are utilized in mass storage devices, motor assemblies, medical equipment, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in compact constructions
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- Neodymium magnets decrease 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 durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Limited ability of creating nuts in the magnet and complex forms - preferred is casing - mounting mechanism.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these products are able to complicate diagnosis medical when they are in the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Pull force analysis
Maximum lifting capacity of the magnet – what contributes to it?
- on a base made of mild steel, effectively closing the magnetic flux
- whose thickness equals approx. 10 mm
- with a plane perfectly flat
- with zero gap (without impurities)
- during pulling in a direction perpendicular to the mounting surface
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin sheet does not close the flux, causing part of the flux to be wasted to the other side.
- Plate material – mild steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate reduces the lifting capacity.
Warnings
Do not overheat magnets
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Sensitization to coating
It is widely known that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, prevent touching magnets with bare hands or select coated magnets.
Crushing force
Risk of injury: The attraction force is so immense that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.
Danger to pacemakers
Life threat: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Material brittleness
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
GPS and phone interference
Remember: neodymium magnets generate a field that disrupts precision electronics. Maintain a separation from your mobile, device, and GPS.
Product not for children
Product intended for adults. Small elements can be swallowed, causing intestinal necrosis. Store away from kids and pets.
Caution required
Handle with care. Neodymium magnets attract from a distance and snap with huge force, often faster than you can move away.
Keep away from computers
Intense magnetic fields can erase data on payment cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
Dust is flammable
Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
