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!

Pros as well as cons of Nd2Fe14B magnets.
Benefits
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (according to literature),
- Neodymium magnets are exceptionally resistant to magnetic field loss caused by external interference,
- The use of an refined coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which allows for strong attraction,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
- Possibility of exact modeling as well as optimizing to concrete conditions,
- Huge importance in electronics industry – they find application in magnetic memories, motor assemblies, medical equipment, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in small systems
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest 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 stable to moisture, in case of application outdoors
- Limited ability of creating threads in the magnet and complicated forms - preferred is a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Additionally, small components of these magnets can be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Best holding force of the magnet in ideal parameters – what affects it?
- with the use of a sheet made of special test steel, guaranteeing maximum field concentration
- whose transverse dimension is min. 10 mm
- characterized by lack of roughness
- without the slightest air gap between the magnet and steel
- during detachment in a direction vertical to the mounting surface
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Plate material – low-carbon steel attracts best. Higher carbon content decrease magnetic permeability and lifting capacity.
- Surface structure – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was assessed with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet and the plate decreases the holding force.
Warnings
Pacemakers
Individuals with a pacemaker must maintain an safe separation from magnets. The magnetism can interfere with the operation of the implant.
Magnetic media
Avoid bringing magnets near a wallet, laptop, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
Do not drill into magnets
Mechanical processing of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Fragile material
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
No play value
Strictly store magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are very dangerous.
Avoid contact if allergic
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, cease handling magnets and use protective gear.
Pinching danger
Big blocks can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.
Maximum temperature
Avoid heat. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Phone sensors
A powerful magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Maintain magnets close to a smartphone to prevent breaking the sensors.
Handling guide
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
