💡 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 Nd2Fe14B magnets.
Advantages
- They retain magnetic properties for around 10 years – the loss is just ~1% (in theory),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- Thanks to the glossy finish, the layer of nickel, gold-plated, or silver-plated gives an professional appearance,
- They show high magnetic induction at the operating surface, which increases their power,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to the option of accurate shaping and adaptation to unique requirements, NdFeB magnets can be manufactured in a wide range of forms and dimensions, which amplifies use scope,
- Universal use in modern technologies – they are commonly used in hard drives, electric drive systems, medical devices, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which enables their usage in small systems
Weaknesses
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating nuts in the magnet and complex forms - recommended is a housing - magnet mounting.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these magnets can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- using a plate made of low-carbon steel, functioning as a circuit closing element
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with an ideally smooth contact surface
- without the slightest insulating layer between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Air gap (between the magnet and the metal), since even a tiny distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Direction of force – highest force is reached only during perpendicular pulling. The shear force of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys attracts identically. High carbon content worsen the attraction effect.
- Surface finish – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently damage the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet and the plate decreases the lifting capacity.
Safe handling of NdFeB magnets
Data carriers
Data protection: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).
This is not a toy
Absolutely store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are life-threatening.
Fire risk
Powder produced during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Immense force
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Finger safety
Risk of injury: The pulling power is so great that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.
Precision electronics
A powerful magnetic field negatively affects the operation of magnetometers in phones and navigation systems. Keep magnets near a smartphone to prevent breaking the sensors.
Health Danger
People with a heart stimulator have to maintain an safe separation from magnets. The magnetic field can stop the operation of the implant.
Fragile material
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
Allergy Warning
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness happens, cease working with magnets and use protective gear.
Heat warning
Regular neodymium magnets (N-type) lose power when the temperature exceeds 80°C. The loss of strength is permanent.
