💡 Guide: How to choose a decent magnet and not get ripped off?
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 have unchanged lifting capacity, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
- Magnets very well protect themselves against demagnetization caused by external fields,
- In other words, due to the glossy finish of nickel, the element becomes visually attractive,
- They show high magnetic induction at the operating surface, making them more effective,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to freedom in constructing and the ability to modify to specific needs,
- Fundamental importance in high-tech industry – they serve a role in data components, drive modules, diagnostic systems, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in small systems
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in force. 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in realizing nuts and complicated forms in magnets, we recommend using a housing - magnetic mount.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Additionally, tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
- Due to complex production process, their price exceeds standard values,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- with the application of a yoke made of special test steel, ensuring full magnetic saturation
- whose transverse dimension reaches at least 10 mm
- characterized by even structure
- under conditions of no distance (surface-to-surface)
- during pulling in a direction vertical to the mounting surface
- at standard ambient temperature
Lifting capacity in real conditions – factors
- Distance – existence of any layer (paint, tape, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Angle of force application – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin steel does not accept the full field, causing part of the flux to be escaped to the other side.
- Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures lower magnetic properties and holding force.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
- Thermal environment – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the holding force.
Safety rules for work with neodymium magnets
Skin irritation risks
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If redness happens, cease working with magnets and wear gloves.
Heat warning
Do not overheat. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
Electronic devices
Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Warning for heart patients
For implant holders: Powerful magnets affect medical devices. Maintain at least 30 cm distance or ask another person to work with the magnets.
Safe operation
Handle magnets consciously. Their immense force can surprise even professionals. Be vigilant and do not underestimate their power.
Dust explosion hazard
Mechanical processing of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Phone sensors
GPS units and mobile phones are highly sensitive to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.
Hand protection
Big blocks can break fingers instantly. Under no circumstances place your hand betwixt two attracting surfaces.
Risk of cracking
Neodymium magnets are ceramic materials, which means they are very brittle. Collision of two magnets will cause them breaking into shards.
Product not for children
These products are not suitable for play. Eating several magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and requires immediate surgery.
