💡 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!

Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- Their power is maintained, and after around 10 years it drops only by ~1% (theoretically),
- They have excellent resistance to magnetic field loss as a result of external fields,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- 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 option of flexible shaping and adaptation to specialized needs, neodymium magnets can be produced in a broad palette of forms and dimensions, which amplifies use scope,
- Versatile presence in future technologies – they are utilized in data components, drive modules, medical devices, also complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in compact constructions
Cons
- At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We suggest casing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complex shapes.
- Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that small elements of these magnets can be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Highest magnetic holding force – what it depends on?
- with the application of a sheet made of special test steel, guaranteeing full magnetic saturation
- possessing a massiveness of min. 10 mm to avoid saturation
- with an ideally smooth touching surface
- without any clearance between the magnet and steel
- under vertical force vector (90-degree angle)
- in neutral thermal conditions
What influences lifting capacity in practice
- Distance – existence of any layer (paint, tape, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin plate does not accept the full field, causing part of the flux to be lost into the air.
- Material composition – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
- Surface structure – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet and the plate reduces the load capacity.
Safe handling of neodymium magnets
Magnets are brittle
Neodymium magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets leads to them shattering into shards.
Allergy Warning
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, immediately stop handling magnets and use protective gear.
Choking Hazard
Neodymium magnets are not suitable for play. Swallowing a few magnets can lead to them attracting across intestines, which poses a critical condition and necessitates immediate surgery.
Bone fractures
Large magnets can smash fingers in a fraction of a second. Do not place your hand between two attracting surfaces.
Machining danger
Fire warning: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
Operating temperature
Do not overheat. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Keep away from computers
Device Safety: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, medical aids, timepieces).
Immense force
Handle magnets with awareness. Their powerful strength can surprise even professionals. Be vigilant and respect their force.
ICD Warning
Medical warning: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Keep away from electronics
Navigation devices and smartphones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
