💡 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 and disadvantages of Nd2Fe14B magnets.
Strengths
- They retain full power for nearly 10 years – the drop is just ~1% (according to analyses),
- Neodymium magnets are distinguished by highly resistant to magnetic field loss caused by magnetic disturbances,
- By covering with a reflective layer of silver, the element presents an elegant look,
- The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to the potential of free shaping and customization to custom requirements, magnetic components can be created in a broad palette of geometric configurations, which expands the range of possible applications,
- Key role in innovative solutions – they are used in mass storage devices, brushless drives, medical equipment, and multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Due to limitations in realizing nuts and complex shapes in magnets, we propose using a housing - magnetic mechanism.
- Possible danger to health – tiny shards of magnets are risky, if swallowed, which gains importance in the context of child health protection. Additionally, small components of these magnets are able to complicate diagnosis medical after entering the body.
- Due to expensive raw materials, their price is relatively high,
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- with the contact of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with an ground touching surface
- without the slightest insulating layer between the magnet and steel
- under perpendicular force direction (90-degree angle)
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Gap (betwixt the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, rust or dirt).
- Angle of force application – highest force is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Plate material – low-carbon steel gives the best results. Higher carbon content decrease magnetic properties and lifting capacity.
- Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
- Temperature – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Metal Allergy
Studies show that nickel (the usual finish) is a strong allergen. For allergy sufferers, refrain from touching magnets with bare hands and choose encased magnets.
Handling guide
Use magnets consciously. Their powerful strength can shock even professionals. Stay alert and respect their power.
Danger to pacemakers
Individuals with a ICD should keep an safe separation from magnets. The magnetism can interfere with the functioning of the implant.
GPS and phone interference
A strong magnetic field interferes with the operation of compasses in phones and navigation systems. Do not bring magnets near a smartphone to avoid damaging the sensors.
Machining danger
Dust generated during machining of magnets is flammable. Do not drill into magnets unless you are an expert.
Magnets are brittle
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Impact of two magnets will cause them cracking into small pieces.
No play value
These products are not toys. Eating multiple magnets can lead to them pinching intestinal walls, which poses a direct threat to life and requires immediate surgery.
Electronic hazard
Avoid bringing magnets near a wallet, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Demagnetization risk
Regular neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. This process is irreversible.
Physical harm
Big blocks can break fingers in a fraction of a second. Under no circumstances put your hand betwixt two strong magnets.
