💡 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 proposals
Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- Their power is durable, and after around 10 years it decreases only by ~1% (according to research),
- They have excellent resistance to magnetic field loss when exposed to external magnetic sources,
- In other words, due to the glossy surface of silver, the element becomes visually attractive,
- They feature high magnetic induction at the operating surface, making them more effective,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
- Thanks to versatility in forming and the capacity to modify to complex applications,
- Fundamental importance in electronics industry – they find application in HDD drives, electric drive systems, diagnostic systems, as well as technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also increases 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 power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of producing threads in the magnet and complex shapes - recommended is casing - magnet mounting.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Furthermore, small elements of these devices can complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Maximum holding power of the magnet – what it depends on?
- using a sheet made of mild steel, functioning as a magnetic yoke
- with a cross-section no less than 10 mm
- with a surface perfectly flat
- with direct contact (no coatings)
- under vertical force vector (90-degree angle)
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Air gap (between the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Plate material – mild steel gives the best results. Alloy admixtures lower magnetic properties and holding force.
- Surface finish – ideal contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal environment – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
H&S for magnets
Keep away from electronics
Be aware: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a separation from your phone, device, and navigation systems.
Protect data
Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).
Magnet fragility
Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
This is not a toy
NdFeB magnets are not suitable for play. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and requires urgent medical intervention.
Do not overheat magnets
Do not overheat. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
Handling guide
Handle magnets consciously. Their huge power can shock even professionals. Plan your moves and respect their force.
Health Danger
Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
Pinching danger
Protect your hands. Two large magnets will join immediately with a force of massive weight, destroying everything in their path. Be careful!
Allergic reactions
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness happens, cease handling magnets and use protective gear.
Flammability
Dust produced during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
