💡 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!

Other products
Strengths as well as weaknesses of neodymium magnets.
Strengths
- They do not lose magnetism, even over around 10 years – the decrease in strength is only ~1% (based on measurements),
- They possess excellent resistance to weakening of magnetic properties due to external fields,
- A magnet with a metallic gold surface is more attractive,
- The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Thanks to flexibility in shaping and the capacity to customize to unusual requirements,
- Key role in high-tech industry – they find application in data components, electric motors, precision medical tools, and multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited ability of producing threads in the magnet and complex forms - preferred is a housing - magnet mounting.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a block made of structural steel, effectively closing the magnetic flux
- with a cross-section minimum 10 mm
- characterized by even structure
- with total lack of distance (without paint)
- under axial application of breakaway force (90-degree angle)
- at temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Distance (between the magnet and the metal), as even a very small distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Plate thickness – insufficiently thick sheet does not accept the full field, causing part of the power to be escaped to the other side.
- Steel type – low-carbon steel gives the best results. Alloy admixtures reduce magnetic properties and holding force.
- Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
- Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was assessed by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.
Safe handling of neodymium magnets
Power loss in heat
Do not overheat. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
Allergic reactions
Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation happens, cease handling magnets and use protective gear.
Pacemakers
Patients with a ICD should maintain an large gap from magnets. The magnetic field can interfere with the operation of the life-saving device.
Physical harm
Large magnets can crush fingers in a fraction of a second. Do not put your hand between two attracting surfaces.
Threat to electronics
Avoid bringing magnets near a wallet, laptop, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
Machining danger
Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.
Handling rules
Use magnets with awareness. Their powerful strength can surprise even professionals. Plan your moves and respect their power.
Risk of cracking
Neodymium magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets leads to them breaking into small pieces.
No play value
Only for adults. Tiny parts pose a choking risk, causing serious injuries. Store out of reach of children and animals.
Precision electronics
Note: neodymium magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your mobile, tablet, and GPS.
