💡 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!

Advantages as well as disadvantages of rare earth magnets.
Pros
- Their magnetic field is maintained, and after around 10 years it drops only by ~1% (theoretically),
- They retain their magnetic properties even under external field action,
- By applying a smooth coating of gold, the element gains an elegant look,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Thanks to flexibility in forming and the capacity to modify to specific needs,
- Wide application in high-tech industry – they are used in hard drives, drive modules, diagnostic systems, also complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Cons
- At 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.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- 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 cover - magnetic mount, due to difficulties in creating threads inside the magnet and complicated shapes.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, small components of these products are able to disrupt the diagnostic process medical after entering the body.
- With mass production the cost of neodymium magnets can be a barrier,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what affects it?
- using a sheet made of high-permeability steel, acting as a circuit closing element
- with a cross-section no less than 10 mm
- with an ground touching surface
- with total lack of distance (no paint)
- during detachment in a direction perpendicular to the mounting surface
- at room temperature
Practical lifting capacity: influencing factors
- Distance (betwixt the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Load vector – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick plate does not accept the full field, causing part of the flux to be wasted to the other side.
- Plate material – mild steel attracts best. Alloy admixtures lower magnetic permeability and holding force.
- Smoothness – full contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, however under shearing force the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
Bone fractures
Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Cards and drives
Device Safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, mechanical watches).
Impact on smartphones
An intense magnetic field negatively affects the operation of compasses in phones and GPS navigation. Maintain magnets close to a smartphone to avoid breaking the sensors.
Avoid contact if allergic
Nickel alert: The Ni-Cu-Ni coating contains nickel. If redness appears, cease handling magnets and wear gloves.
Warning for heart patients
Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Machining danger
Machining of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Magnet fragility
Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Heat sensitivity
Control the heat. Heating the magnet above 80 degrees Celsius will ruin its properties and strength.
Keep away from children
Strictly keep magnets out of reach of children. Choking hazard is high, and the effects of magnets clamping inside the body are very dangerous.
Immense force
Use magnets with awareness. Their huge power can surprise even experienced users. Stay alert and do not underestimate their power.
