💡 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!

Pros as well as cons of rare earth magnets.
Benefits
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- Magnets effectively resist against loss of magnetization caused by external fields,
- By covering with a smooth layer of silver, the element acquires an modern look,
- Magnetic induction on the working part of the magnet is very high,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
- Thanks to the ability of free molding and customization to custom solutions, NdFeB magnets can be modeled in a broad palette of geometric configurations, which expands the range of possible applications,
- Fundamental importance in high-tech industry – they find application in hard drives, electric drive systems, precision medical tools, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in compact constructions
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We suggest casing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complicated shapes.
- Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Furthermore, small components of these devices are able to be problematic in diagnostics medical after entering 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
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- using a base made of high-permeability steel, functioning as a circuit closing element
- with a cross-section of at least 10 mm
- characterized by smoothness
- under conditions of no distance (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- at room temperature
Impact of factors on magnetic holding capacity in practice
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Base massiveness – too thin steel does not close the flux, causing part of the power to be escaped to the other side.
- Material type – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
- Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
- Temperature – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was determined using a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate lowers the holding force.
Safe handling of NdFeB magnets
Do not give to children
Absolutely store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets connecting inside the body are tragic.
Caution required
Use magnets consciously. Their immense force can surprise even experienced users. Plan your moves and respect their power.
Bodily injuries
Protect your hands. Two powerful magnets will join immediately with a force of massive weight, destroying anything in their path. Be careful!
Combustion hazard
Machining of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Avoid contact if allergic
Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, immediately stop working with magnets and wear gloves.
Danger to pacemakers
For implant holders: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.
Threat to electronics
Intense magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
Operating temperature
Keep cool. Neodymium magnets are susceptible to temperature. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
Compass and GPS
GPS units and mobile phones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Magnet fragility
NdFeB magnets are ceramic materials, meaning they are very brittle. Impact of two magnets leads to them shattering into small pieces.
