💡 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!

Pros as well as cons of neodymium magnets.
Strengths
- They retain attractive force for nearly ten years – the drop is just ~1% (in theory),
- Magnets very well protect themselves against loss of magnetization caused by ambient magnetic noise,
- A magnet with a smooth silver surface has an effective appearance,
- They show high magnetic induction at the operating surface, making them more effective,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Thanks to flexibility in constructing and the capacity to modify to unusual requirements,
- Fundamental importance in future technologies – they find application in mass storage devices, drive modules, diagnostic systems, and complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Disadvantages
- At very strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 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 producing threads and complicated forms in magnets, we recommend using a housing - magnetic holder.
- Health risk to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. Additionally, small components of these products are able to disrupt the diagnostic process medical after entering the body.
- With large orders the cost of neodymium magnets is economically unviable,
Pull force analysis
Maximum magnetic pulling force – what it depends on?
- using a sheet made of low-carbon steel, serving as a circuit closing element
- possessing a thickness of min. 10 mm to ensure full flux closure
- characterized by lack of roughness
- under conditions of gap-free contact (surface-to-surface)
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature room level
Lifting capacity in real conditions – factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
- Steel thickness – insufficiently thick steel causes magnetic saturation, causing part of the flux to be wasted into the air.
- Plate material – mild steel gives the best results. Alloy steels reduce magnetic permeability and holding force.
- Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Thermal factor – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under shearing force the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate decreases the holding force.
Precautions when working with NdFeB magnets
GPS Danger
Remember: rare earth magnets produce a field that interferes with precision electronics. Keep a separation from your mobile, device, and GPS.
Powerful field
Exercise caution. Neodymium magnets act from a long distance and connect with huge force, often faster than you can react.
Power loss in heat
Avoid heat. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Allergy Warning
A percentage of the population have a contact allergy to Ni, which is the typical protective layer for NdFeB magnets. Extended handling might lead to a rash. We suggest use safety gloves.
Dust is flammable
Combustion risk: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.
Protect data
Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, medical aids, mechanical watches).
Adults only
Always store magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are life-threatening.
Bone fractures
Protect your hands. Two large magnets will snap together immediately with a force of massive weight, crushing everything in their path. Be careful!
Shattering risk
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
ICD Warning
Patients with a heart stimulator should maintain an large gap from magnets. The magnetic field can interfere with the functioning of the implant.
