💡 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!

Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
- Magnets very well defend themselves against loss of magnetization caused by foreign field sources,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnets possess exceptionally strong magnetic induction on the outer layer,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to the option of free molding and customization to custom needs, NdFeB magnets can be manufactured in a wide range of shapes and sizes, which makes them more universal,
- Versatile presence in modern industrial fields – they serve a role in computer drives, motor assemblies, diagnostic systems, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in miniature devices
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing threads and complicated forms in magnets, we propose using casing - magnetic mount.
- Health risk resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these devices 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
Maximum holding power of the magnet – what it depends on?
- using a base made of low-carbon steel, functioning as a circuit closing element
- whose transverse dimension equals approx. 10 mm
- characterized by lack of roughness
- under conditions of ideal adhesion (metal-to-metal)
- under perpendicular force direction (90-degree angle)
- in neutral thermal conditions
Lifting capacity in practice – influencing factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Plate thickness – too thin sheet does not close the flux, causing part of the power to be wasted to the other side.
- Metal type – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Surface quality – the more even the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the load capacity.
H&S for magnets
Do not underestimate power
Handle magnets with awareness. Their huge power can surprise even professionals. Be vigilant and respect their force.
Avoid contact if allergic
Medical facts indicate that nickel (the usual finish) is a potent allergen. If your skin reacts to metals, refrain from direct skin contact or opt for encased magnets.
Risk of cracking
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Do not overheat magnets
Monitor thermal conditions. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.
Mechanical processing
Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
GPS Danger
A powerful magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Keep magnets near a smartphone to prevent damaging the sensors.
Medical implants
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Magnetic media
Intense magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Stay away of at least 10 cm.
Keep away from children
Absolutely store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are life-threatening.
Bone fractures
Big blocks can break fingers instantly. Never place your hand betwixt two attracting surfaces.
