💡 Check why professionals choose Dhit over cheap substitutes
Instead of believing fairy tales on YouTube with tests on uncertified equipment, see what really determines your magnet's power:
- 📏 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 offers
Pros as well as cons of rare earth magnets.
Pros
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (according to literature),
- They have excellent resistance to magnetic field loss as a result of external fields,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to look better,
- Neodymium magnets generate maximum magnetic induction on a small area, which allows for strong attraction,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Possibility of exact shaping and optimizing to defined needs,
- Significant place in innovative solutions – they are utilized in data components, electric drive systems, advanced medical instruments, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in compact constructions
Disadvantages
- At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We suggest casing - magnetic mount, due to difficulties in creating threads inside the magnet and complex shapes.
- Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these products are able to disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
- possessing a thickness of minimum 10 mm to avoid saturation
- with a surface perfectly flat
- without any air gap between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Distance (betwixt the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- 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 – ideal substrate is pure iron steel. Stainless steels may attract less.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet and the plate decreases the lifting capacity.
H&S for magnets
Keep away from electronics
GPS units and mobile phones are highly susceptible to magnetism. Direct contact with a strong magnet can ruin the sensors in your phone.
Protective goggles
Watch out for shards. Magnets can fracture upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Finger safety
Danger of trauma: The pulling power is so immense that it can cause hematomas, crushing, and even bone fractures. Protective gloves are recommended.
Combustion hazard
Powder produced during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Permanent damage
Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
Medical interference
For implant holders: Powerful magnets affect medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.
Adults only
Always keep magnets away from children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are tragic.
Allergy Warning
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, immediately stop working with magnets and use protective gear.
Data carriers
Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).
Do not underestimate power
Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
