💡 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!

Pros and cons of rare earth magnets.
Pros
- They do not lose power, even during around ten years – the drop in lifting capacity is only ~1% (according to tests),
- They maintain their magnetic properties even under close interference source,
- By using a decorative layer of silver, the element presents an modern look,
- Magnets are characterized by extremely high magnetic induction on the working surface,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to freedom in constructing and the capacity to modify to unusual requirements,
- Versatile presence in modern technologies – they serve a role in hard drives, electric motors, advanced medical instruments, as well as multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complicated shapes in magnets, we recommend using a housing - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child safety. Furthermore, small components of these magnets can be problematic in diagnostics medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is economically unviable,
Lifting parameters
Maximum lifting capacity of the magnet – what it depends on?
- with the contact of a yoke made of special test steel, guaranteeing maximum field concentration
- whose thickness equals approx. 10 mm
- with a plane cleaned and smooth
- without any insulating layer between the magnet and steel
- under vertical force direction (90-degree angle)
- at standard ambient temperature
Lifting capacity in real conditions – factors
- Clearance – existence of any layer (rust, tape, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Direction of force – highest force is obtained only during perpendicular pulling. The shear force of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Chemical composition of the base – low-carbon steel attracts best. Alloy admixtures decrease magnetic properties and lifting capacity.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
H&S for magnets
Product not for children
Always keep magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are life-threatening.
Protective goggles
Neodymium magnets are sintered ceramics, which means they are very brittle. Clashing of two magnets leads to them shattering into small pieces.
Compass and GPS
An intense magnetic field interferes with the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets near a device to avoid damaging the sensors.
Safe operation
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Operating temperature
Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Machining danger
Combustion risk: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.
Threat to electronics
Avoid bringing magnets near a wallet, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.
Metal Allergy
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, cease handling magnets and wear gloves.
Danger to pacemakers
For implant holders: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or request help to handle the magnets.
Bodily injuries
Large magnets can crush fingers instantly. Do not put your hand between two attracting surfaces.
