💡 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 and cons of neodymium magnets.
Benefits
- Their strength remains stable, and after around 10 years it decreases only by ~1% (according to research),
- Neodymium magnets remain extremely resistant to demagnetization caused by magnetic disturbances,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of exact machining and adapting to defined requirements,
- Key role in advanced technology sectors – they are commonly used in computer drives, motor assemblies, precision medical tools, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in compact constructions
Disadvantages
- At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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 extremely resistant to heat
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of creating nuts in the magnet and complicated forms - preferred is a housing - magnet mounting.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these devices can be problematic in diagnostics medical after entering the body.
- Due to expensive raw materials, their price is higher than average,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what it depends on?
- using a sheet made of high-permeability steel, acting as a magnetic yoke
- with a thickness no less than 10 mm
- characterized by smoothness
- without any air gap between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at standard ambient temperature
Magnet lifting force in use – key factors
- Air gap (between the magnet and the metal), since even a tiny clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to paint, corrosion or dirt).
- Load vector – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Material type – ideal substrate is high-permeability steel. Stainless steels may attract less.
- Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Crushing risk
Pinching hazard: The attraction force is so immense that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.
Shattering risk
Protect your eyes. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
Do not give to children
Product intended for adults. Small elements can be swallowed, causing serious injuries. Keep out of reach of children and animals.
Warning for allergy sufferers
Some people experience a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Extended handling may cause a rash. We suggest use safety gloves.
Heat sensitivity
Keep cool. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).
Keep away from computers
Device Safety: Neodymium magnets can damage data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
Warning for heart patients
Life threat: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
GPS Danger
GPS units and smartphones are highly susceptible to magnetic fields. Direct contact with a strong magnet can permanently damage the internal compass in your phone.
Dust explosion hazard
Machining of neodymium magnets carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Conscious usage
Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
