💡 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 retain attractive force for nearly ten years – the drop is just ~1% (in theory),
- Neodymium magnets are distinguished by remarkably resistant to demagnetization caused by external magnetic fields,
- The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnetic induction on the working part of the magnet turns out to be exceptional,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of exact machining and adjusting to specific applications,
- Significant place in modern technologies – they are used in magnetic memories, brushless drives, precision medical tools, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in small systems
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend cover - magnetic mechanism, due to difficulties in creating threads inside the magnet and complex shapes.
- Health risk to health – tiny shards of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets can complicate diagnosis medical when they are in the body.
- Due to complex production process, their price is higher than average,
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- using a sheet made of high-permeability steel, serving as a magnetic yoke
- possessing a thickness of minimum 10 mm to ensure full flux closure
- characterized by smoothness
- under conditions of gap-free contact (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at standard ambient temperature
Lifting capacity in practice – influencing factors
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is reached only during perpendicular pulling. The shear force of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick plate causes magnetic saturation, causing part of the power to be lost to the other side.
- Steel type – low-carbon steel gives the best results. Higher carbon content reduce magnetic properties and lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which improves force. Rough surfaces reduce efficiency.
- Thermal factor – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under shearing force the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the holding force.
H&S for magnets
Permanent damage
Keep cool. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
ICD Warning
People with a ICD have to keep an absolute distance from magnets. The magnetism can disrupt the functioning of the life-saving device.
Choking Hazard
Neodymium magnets are not suitable for play. Eating several magnets can lead to them connecting inside the digestive tract, which poses a critical condition and requires immediate surgery.
Avoid contact if allergic
Some people experience a sensitization to nickel, which is the standard coating for NdFeB magnets. Frequent touching might lead to skin redness. It is best to wear safety gloves.
Crushing risk
Mind your fingers. Two powerful magnets will snap together immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!
Risk of cracking
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets leads to them breaking into shards.
Threat to navigation
GPS units and smartphones are highly sensitive to magnetism. Direct contact with a strong magnet can ruin the sensors in your phone.
Immense force
Be careful. Neodymium magnets act from a long distance and snap with massive power, often faster than you can move away.
Cards and drives
Very strong magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Dust is flammable
Powder generated during machining of magnets is flammable. Avoid drilling into magnets unless you are an expert.
