💡 Guide: How to choose a decent magnet and not get ripped off?
Don't be fooled by amateur online tests – go for certified quality and specific parameters that guarantee success:
- 📏 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 and cons of Nd2Fe14B magnets.
Advantages
- They do not lose magnetism, even during nearly 10 years – the reduction in strength is only ~1% (theoretically),
- Magnets effectively defend themselves against loss of magnetization caused by ambient magnetic noise,
- In other words, due to the glossy finish of nickel, the element is aesthetically pleasing,
- Magnets exhibit exceptionally strong magnetic induction on the surface,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of custom shaping and adjusting to specific applications,
- Significant place in innovative solutions – they are used in hard drives, electromotive mechanisms, medical equipment, as well as multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
- Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Limited possibility of producing threads in the magnet and complicated forms - preferred is cover - magnet mounting.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these magnets can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Magnetic strength at its maximum – what contributes to it?
- on a base made of mild steel, perfectly concentrating the magnetic flux
- whose thickness is min. 10 mm
- with a surface cleaned and smooth
- under conditions of no distance (surface-to-surface)
- under vertical force direction (90-degree angle)
- at conditions approx. 20°C
Practical aspects of lifting capacity – factors
- Air gap (betwixt the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, rust or debris).
- Direction of force – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Steel type – low-carbon steel gives the best results. Higher carbon content lower magnetic properties and lifting capacity.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal environment – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.
H&S for magnets
Permanent damage
Avoid heat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, look for HT versions (H, SH, UH).
Pinching danger
Big blocks can break fingers instantly. Never place your hand betwixt two attracting surfaces.
Do not drill into magnets
Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
GPS Danger
A powerful magnetic field negatively affects the functioning of compasses in phones and navigation systems. Do not bring magnets close to a device to prevent breaking the sensors.
Protect data
Data protection: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
Life threat
Individuals with a heart stimulator must maintain an safe separation from magnets. The magnetic field can disrupt the functioning of the implant.
Allergy Warning
Nickel alert: The Ni-Cu-Ni coating contains nickel. If redness appears, immediately stop working with magnets and use protective gear.
Eye protection
Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.
No play value
Adult use only. Tiny parts pose a choking risk, leading to severe trauma. Keep out of reach of kids and pets.
Safe operation
Exercise caution. Neodymium magnets act from a long distance and connect with massive power, often faster than you can move away.
