💡 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 as well as disadvantages of rare earth magnets.
Benefits
- They have unchanged lifting capacity, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- A magnet with a shiny nickel surface looks better,
- Neodymium magnets create maximum magnetic induction on a small surface, which allows for strong attraction,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
- Due to the potential of precise forming and adaptation to custom needs, magnetic components can be manufactured in a variety of geometric configurations, which expands the range of possible applications,
- Significant place in future technologies – they are utilized in HDD drives, drive modules, advanced medical instruments, also industrial machines.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures 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
- We recommend casing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex forms.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- using a base made of low-carbon steel, functioning as a ideal flux conductor
- possessing a thickness of min. 10 mm to avoid saturation
- characterized by smoothness
- without any clearance between the magnet and steel
- under axial force direction (90-degree angle)
- at temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Distance – the presence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Material composition – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was determined by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Warnings
Electronic hazard
Data protection: Strong magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
Mechanical processing
Dust produced during cutting of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Sensitization to coating
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, cease handling magnets and wear gloves.
Fragile material
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Do not underestimate power
Use magnets consciously. Their immense force can surprise even experienced users. Stay alert and do not underestimate their force.
Do not give to children
Product intended for adults. Small elements can be swallowed, causing severe trauma. Store out of reach of kids and pets.
Bodily injuries
Large magnets can crush fingers in a fraction of a second. Do not place your hand between two attracting surfaces.
Phone sensors
GPS units and smartphones are highly sensitive to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Medical implants
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Do not overheat magnets
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. The loss of strength is permanent.
