💡 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.
Pros
- They have stable power, and over around ten years their performance decreases symbolically – ~1% (according to theory),
- Magnets perfectly defend themselves against demagnetization caused by ambient magnetic noise,
- In other words, due to the aesthetic surface of nickel, the element is aesthetically pleasing,
- Neodymium magnets create maximum magnetic induction on a small area, which ensures high operational effectiveness,
- 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 versatility in designing and the capacity to modify to unusual requirements,
- Versatile presence in modern industrial fields – they are utilized in hard drives, electric drive systems, precision medical tools, and industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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 very resistant to heat
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating threads in the magnet and complex forms - preferred is a housing - magnet mounting.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- With budget limitations the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum holding power of the magnet – what affects it?
- on a base made of structural steel, effectively closing the magnetic flux
- with a thickness no less than 10 mm
- with a surface free of scratches
- with direct contact (no paint)
- during detachment in a direction perpendicular to the plane
- at room temperature
Practical lifting capacity: influencing factors
- Clearance – existence of any layer (rust, tape, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
- Plate texture – ground elements guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate lowers the load capacity.
Safety rules for work with NdFeB magnets
GPS and phone interference
Remember: neodymium magnets generate a field that confuses precision electronics. Maintain a separation from your phone, tablet, and GPS.
Bodily injuries
Large magnets can crush fingers in a fraction of a second. Never place your hand betwixt two attracting surfaces.
Caution required
Handle magnets with awareness. Their immense force can shock even professionals. Stay alert and respect their power.
Heat warning
Avoid heat. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
Avoid contact if allergic
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, cease working with magnets and wear gloves.
Danger to pacemakers
Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Shattering risk
Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Keep away from computers
Equipment safety: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).
Product not for children
Always store magnets away from children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are tragic.
Dust explosion hazard
Mechanical processing of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
