💡 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 as well as cons of rare earth magnets.
Advantages
- They do not lose power, even during approximately 10 years – the drop in lifting capacity is only ~1% (based on measurements),
- They do not lose their magnetic properties even under close interference source,
- Thanks to the metallic finish, the surface of Ni-Cu-Ni, gold, or silver-plated gives an visually attractive appearance,
- They show high magnetic induction at the operating surface, which increases their power,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures reaching 230°C and above...
- Thanks to flexibility in designing and the capacity to adapt to specific needs,
- Wide application in modern technologies – they find application in data components, electric motors, advanced medical instruments, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in small systems
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We recommend a housing - magnetic holder, due to difficulties in realizing threads inside the magnet and complex shapes.
- Health risk resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Furthermore, tiny parts of these magnets can disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- on a plate made of mild steel, optimally conducting the magnetic flux
- whose transverse dimension is min. 10 mm
- with an polished contact surface
- with zero gap (without paint)
- under vertical force direction (90-degree angle)
- at conditions approx. 20°C
Lifting capacity in practice – influencing factors
- Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Material composition – different alloys attracts identically. Alloy additives worsen the attraction effect.
- Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces weaken the grip.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet’s surface and the plate reduces the holding force.
H&S for magnets
Precision electronics
Remember: neodymium magnets generate a field that confuses precision electronics. Maintain a separation from your mobile, device, and GPS.
Keep away from computers
Equipment safety: Strong magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).
ICD Warning
Medical warning: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
No play value
Product intended for adults. Small elements can be swallowed, leading to severe trauma. Store out of reach of children and animals.
Handling guide
Use magnets consciously. Their huge power can shock even experienced users. Plan your moves and respect their power.
Pinching danger
Protect your hands. Two large magnets will snap together instantly with a force of massive weight, destroying everything in their path. Be careful!
Allergy Warning
A percentage of the population experience a contact allergy to nickel, which is the common plating for neodymium magnets. Extended handling might lead to dermatitis. We recommend wear protective gloves.
Beware of splinters
Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
Demagnetization risk
Monitor thermal conditions. Exposing the magnet to high heat will ruin its properties and pulling force.
Do not drill into magnets
Fire warning: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
