💡 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!

Strengths and weaknesses of rare earth magnets.
Pros
- Their magnetic field is durable, and after approximately 10 years it decreases only by ~1% (theoretically),
- They are extremely resistant to demagnetization induced by external magnetic fields,
- The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to look better,
- Neodymium magnets create maximum magnetic induction on a contact point, which allows for strong attraction,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
- In view of the option of accurate shaping and adaptation to specialized solutions, NdFeB magnets can be created in a variety of geometric configurations, which makes them more universal,
- Huge importance in electronics industry – they are utilized in data components, electric motors, medical devices, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in small systems
Disadvantages
- At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 extremely 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 stable to moisture, when using outdoors
- Due to limitations in producing nuts and complicated forms in magnets, we recommend using a housing - magnetic mount.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which becomes key in the context of child health protection. Furthermore, tiny parts of these devices can complicate diagnosis medical in case of swallowing.
- With mass production the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum magnetic pulling force – what it depends on?
- with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
- possessing a thickness of min. 10 mm to avoid saturation
- with a surface free of scratches
- under conditions of ideal adhesion (metal-to-metal)
- under perpendicular force vector (90-degree angle)
- at temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Gap (between the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, corrosion or debris).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Steel thickness – insufficiently thick sheet does not accept the full field, causing part of the flux to be lost to the other side.
- Chemical composition of the base – mild steel gives the best results. Higher carbon content lower magnetic properties and lifting capacity.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, however under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with NdFeB magnets
Magnetic interference
Be aware: rare earth magnets produce a field that confuses sensitive sensors. Keep a safe distance from your phone, device, and GPS.
Warning for heart patients
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Maximum temperature
Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its properties and pulling force.
Electronic hazard
Device Safety: Strong magnets can damage data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).
Adults only
Adult use only. Tiny parts can be swallowed, leading to severe trauma. Store away from kids and pets.
Do not drill into magnets
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Caution required
Handle with care. Rare earth magnets act from a distance and snap with huge force, often quicker than you can move away.
Eye protection
NdFeB magnets are ceramic materials, which means they are very brittle. Clashing of two magnets leads to them breaking into shards.
Bodily injuries
Pinching hazard: The attraction force is so immense that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Avoid contact if allergic
Nickel alert: The nickel-copper-nickel coating contains nickel. If skin irritation happens, cease handling magnets and wear gloves.
