💡 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 Nd2Fe14B magnets.
Pros
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- They retain their magnetic properties even under external field action,
- A magnet with a metallic nickel surface looks better,
- Magnets possess excellent magnetic induction on the outer layer,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Due to the option of accurate molding and customization to custom needs, magnetic components can be manufactured in a variety of forms and dimensions, which makes them more universal,
- Huge importance in future technologies – they are commonly used in hard drives, electromotive mechanisms, medical equipment, also other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also increases their durability
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- We suggest a housing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Health risk resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, tiny parts of these products are able to be problematic in diagnostics medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum magnetic pulling force – what contributes to it?
- using a sheet made of low-carbon steel, acting as a circuit closing element
- with a cross-section of at least 10 mm
- with an polished contact surface
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction perpendicular to the plane
- at ambient temperature room level
Practical lifting capacity: influencing factors
- Clearance – existence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Steel thickness – too thin plate does not close the flux, causing part of the flux to be escaped into the air.
- Material composition – not every steel attracts identically. High carbon content worsen the attraction effect.
- Plate texture – ground elements ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
- Temperature influence – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under shearing force the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
H&S for magnets
Keep away from children
Always keep magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are very dangerous.
Warning for heart patients
Patients with a ICD must maintain an large gap from magnets. The magnetism can stop the functioning of the implant.
Compass and GPS
Be aware: rare earth magnets generate a field that interferes with precision electronics. Keep a safe distance from your phone, device, and GPS.
Hand protection
Big blocks can smash fingers instantly. Do not put your hand between two attracting surfaces.
Caution required
Use magnets consciously. Their immense force can surprise even professionals. Be vigilant and do not underestimate their power.
Machining danger
Dust created during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Power loss in heat
Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Threat to electronics
Do not bring magnets close to a wallet, computer, or TV. The magnetism can permanently damage these devices and wipe information from cards.
Nickel allergy
A percentage of the population suffer from a sensitization to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact might lead to a rash. We suggest wear safety gloves.
Eye protection
Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
