💡 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 as well as weaknesses of neodymium magnets.
Pros
- They do not lose magnetism, even after nearly 10 years – the drop in strength is only ~1% (theoretically),
- They possess excellent resistance to magnetic field loss as a result of external magnetic sources,
- Thanks to the reflective finish, the layer of nickel, gold-plated, or silver gives an modern appearance,
- Neodymium magnets ensure maximum magnetic induction on a small surface, which increases force concentration,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
- Thanks to the option of precise molding and adaptation to specialized solutions, magnetic components can be modeled in a variety of forms and dimensions, which increases their versatility,
- Significant place in innovative solutions – they find application in computer drives, electric drive systems, medical equipment, also multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- 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 secures them against impacts but also increases their durability
- Neodymium magnets lose force 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 extremely resistant to heat
- They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complex shapes.
- Health risk resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child safety. It is also worth noting that tiny parts of these devices can be problematic in diagnostics medical when they are in the body.
- With large orders the cost of neodymium magnets is economically unviable,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what it depends on?
- using a base made of high-permeability steel, acting as a circuit closing element
- with a thickness no less than 10 mm
- characterized by smoothness
- without the slightest clearance between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- in temp. approx. 20°C
Determinants of practical lifting force of a magnet
- Gap (between the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Angle of force application – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Wall 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.
- Material type – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Smoothness – full contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate reduces the holding force.
Precautions when working with neodymium magnets
Sensitization to coating
Some people suffer from a sensitization to Ni, which is the common plating for NdFeB magnets. Prolonged contact might lead to skin redness. We suggest wear safety gloves.
Bone fractures
Large magnets can smash fingers in a fraction of a second. Under no circumstances put your hand between two attracting surfaces.
Medical interference
Individuals with a ICD must maintain an large gap from magnets. The magnetic field can interfere with the functioning of the implant.
Permanent damage
Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
Shattering risk
Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. Wear goggles.
Handling guide
Handle with care. Rare earth magnets act from a distance and snap with huge force, often faster than you can react.
Electronic hazard
Very strong magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.
No play value
Adult use only. Tiny parts pose a choking risk, leading to intestinal necrosis. Store out of reach of children and animals.
Keep away from electronics
A strong magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Keep magnets close to a device to prevent damaging the sensors.
Combustion hazard
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
