💡 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!

Advantages and disadvantages of rare earth magnets.
Benefits
- They retain full power for almost ten years – the drop is just ~1% (in theory),
- Magnets effectively defend themselves against demagnetization caused by ambient magnetic noise,
- In other words, due to the glossy layer of gold, the element gains visual value,
- Neodymium magnets achieve maximum magnetic induction on a their surface, which increases force concentration,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of detailed forming and adjusting to complex applications,
- Huge importance in future technologies – they find application in computer drives, electric drive systems, advanced medical instruments, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in compact constructions
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- NdFeB magnets demagnetize 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 very 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 those in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited possibility of producing threads in the magnet and complicated shapes - preferred is cover - magnetic holder.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. Additionally, small components of these magnets are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Maximum lifting force for a neodymium magnet – what affects it?
- on a block made of mild steel, perfectly concentrating the magnetic field
- whose thickness equals approx. 10 mm
- characterized by smoothness
- with total lack of distance (no coatings)
- under perpendicular application of breakaway force (90-degree angle)
- in stable room temperature
Lifting capacity in real conditions – factors
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Metal type – not every steel reacts the same. Alloy additives weaken the attraction effect.
- Smoothness – ideal contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.
Precautions when working with NdFeB magnets
Powerful field
Before starting, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.
Do not overheat magnets
Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
Allergy Warning
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, cease working with magnets and wear gloves.
Physical harm
Large magnets can break fingers instantly. Do not place your hand between two strong magnets.
Dust explosion hazard
Dust generated during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Life threat
Warning for patients: Powerful magnets affect medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Protective goggles
Despite metallic appearance, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Keep away from computers
Very strong magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.
Keep away from electronics
Navigation devices and smartphones are highly susceptible to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.
Choking Hazard
Strictly keep magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets connecting inside the body are very dangerous.
