💡 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!

Advantages as well as disadvantages of neodymium magnets.
Advantages
- They have unchanged lifting capacity, and over around ten years their attraction force decreases symbolically – ~1% (in testing),
- They retain their magnetic properties even under strong external field,
- By applying a reflective coating of nickel, the element acquires an modern look,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
- Thanks to the option of accurate shaping and adaptation to unique requirements, magnetic components can be modeled in a broad palette of shapes and sizes, which makes them more universal,
- Significant place in high-tech industry – they are commonly used in data components, electric drive systems, advanced medical instruments, and industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing threads and complicated shapes in magnets, we propose using casing - magnetic mechanism.
- Health risk resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small elements of these products are able to disrupt the diagnostic process medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the use of a yoke made of low-carbon steel, ensuring full magnetic saturation
- with a thickness minimum 10 mm
- characterized by even structure
- without any insulating layer between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Key elements affecting lifting force
- Space between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Material type – the best choice is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
Thermal limits
Control the heat. Heating the magnet to high heat will destroy its magnetic structure and strength.
Do not drill into magnets
Powder produced during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Medical implants
Patients with a pacemaker have to maintain an absolute distance from magnets. The magnetism can stop the functioning of the implant.
Keep away from electronics
Remember: rare earth magnets produce a field that confuses sensitive sensors. Keep a safe distance from your mobile, device, and GPS.
Electronic devices
Intense magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Stay away of min. 10 cm.
Safe operation
Handle magnets with awareness. Their immense force can surprise even professionals. Stay alert and do not underestimate their power.
Warning for allergy sufferers
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, cease working with magnets and use protective gear.
Adults only
Neodymium magnets are not intended for children. Accidental ingestion of multiple magnets can lead to them attracting across intestines, which poses a severe health hazard and necessitates urgent medical intervention.
Beware of splinters
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Crushing force
Risk of injury: The attraction force is so immense that it can result in hematomas, pinching, and even bone fractures. Protective gloves are recommended.
