💡 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 rare earth magnets.
Pros
- Their magnetic field remains stable, and after approximately ten years it decreases only by ~1% (according to research),
- They are extremely resistant to demagnetization induced by external magnetic fields,
- By covering with a decorative coating of gold, the element presents an proper look,
- Magnetic induction on the working part of the magnet remains impressive,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of accurate creating as well as modifying to precise needs,
- Key role in future technologies – they serve a role in magnetic memories, electric motors, advanced medical instruments, also technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets lose their strength 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 durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing nuts and complex forms in magnets, we propose using casing - magnetic mechanism.
- Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these products can complicate diagnosis medical when they are in the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Lifting parameters
Maximum magnetic pulling force – what affects it?
- using a sheet made of high-permeability steel, serving as a ideal flux conductor
- with a thickness minimum 10 mm
- with a surface cleaned and smooth
- with total lack of distance (no impurities)
- under axial force direction (90-degree angle)
- at temperature room level
Magnet lifting force in use – key factors
- Clearance – existence of foreign body (paint, tape, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
- Surface finish – full contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
- Temperature – heating the magnet results in weakening of force. Check the thermal limit for a given model.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Permanent damage
Do not overheat. Neodymium magnets are sensitive to temperature. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
Protective goggles
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Combustion hazard
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Skin irritation risks
Some people suffer from a contact allergy to nickel, which is the standard coating for NdFeB magnets. Prolonged contact might lead to skin redness. We strongly advise use protective gloves.
ICD Warning
Warning for patients: Strong magnetic fields affect electronics. Keep at least 30 cm distance or ask another person to handle the magnets.
Adults only
NdFeB magnets are not intended for children. Eating multiple magnets can lead to them attracting across intestines, which poses a critical condition and necessitates urgent medical intervention.
Cards and drives
Intense magnetic fields can destroy records on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.
Phone sensors
Remember: rare earth magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your phone, device, and GPS.
Bone fractures
Pinching hazard: The pulling power is so great that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.
Safe operation
Handle magnets consciously. Their powerful strength can shock even professionals. Stay alert and do not underestimate their force.
