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 and weaknesses of neodymium magnets.
Advantages
- They do not lose strength, even during nearly ten years – the drop in strength is only ~1% (according to tests),
- Magnets effectively defend themselves against demagnetization caused by ambient magnetic noise,
- A magnet with a metallic nickel surface has an effective appearance,
- The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of accurate creating and optimizing to atypical applications,
- Fundamental importance in electronics industry – they serve a role in hard drives, electromotive mechanisms, medical devices, also technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and 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
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- We recommend cover - magnetic holder, due to difficulties in creating nuts inside the magnet and complex shapes.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Additionally, small components of these magnets can be problematic in diagnostics medical in case of swallowing.
- Due to neodymium price, their price is higher than average,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what it depends on?
- using a plate made of mild steel, acting as a ideal flux conductor
- possessing a thickness of at least 10 mm to avoid saturation
- characterized by lack of roughness
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction perpendicular to the plane
- in temp. approx. 20°C
Determinants of practical lifting force of a magnet
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
- Steel type – mild steel attracts best. Alloy admixtures lower magnetic properties and holding force.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity was assessed with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Safe handling of neodymium magnets
Protect data
Avoid bringing magnets close to a purse, laptop, or TV. The magnetic field can destroy these devices and erase data from cards.
Precision electronics
GPS units and mobile phones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Combustion hazard
Powder created during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Do not underestimate power
Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Protective goggles
Beware of splinters. Magnets can fracture upon violent connection, launching shards into the air. Eye protection is mandatory.
Serious injuries
Large magnets can smash fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.
Demagnetization risk
Avoid heat. Neodymium magnets are susceptible to temperature. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
Allergic reactions
Certain individuals have a contact allergy to nickel, which is the standard coating for NdFeB magnets. Frequent touching can result in a rash. It is best to wear protective gloves.
Danger to pacemakers
For implant holders: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.
Swallowing risk
NdFeB magnets are not toys. Swallowing a few magnets can lead to them pinching intestinal walls, which constitutes a critical condition and necessitates urgent medical intervention.
