💡 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 Nd2Fe14B magnets.
Strengths
- They retain attractive force for around ten years – the loss is just ~1% (based on simulations),
- They feature excellent resistance to weakening of magnetic properties as a result of external magnetic sources,
- In other words, due to the metallic finish of silver, the element gains a professional look,
- Magnetic induction on the top side of the magnet turns out to be very high,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- In view of the possibility of accurate shaping and customization to specialized requirements, NdFeB magnets can be modeled in a broad palette of forms and dimensions, which makes them more universal,
- Versatile presence in high-tech industry – they serve a role in magnetic memories, brushless drives, advanced medical instruments, also other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose their strength 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 usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited ability of making nuts in the magnet and complicated shapes - preferred is cover - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these devices are able to disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Maximum magnetic pulling force – what affects it?
- with the contact of a sheet made of low-carbon steel, ensuring maximum field concentration
- possessing a massiveness of min. 10 mm to avoid saturation
- characterized by even structure
- under conditions of ideal adhesion (metal-to-metal)
- under perpendicular force direction (90-degree angle)
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Stainless steels may generate lower lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet and the plate lowers the load capacity.
Warnings
Medical implants
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Magnetic media
Avoid bringing magnets close to a purse, laptop, or screen. The magnetism can destroy these devices and erase data from cards.
Nickel allergy
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, immediately stop working with magnets and wear gloves.
Conscious usage
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Adults only
Always store magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are fatal.
Phone sensors
A powerful magnetic field disrupts the operation of compasses in smartphones and navigation systems. Do not bring magnets close to a smartphone to avoid damaging the sensors.
Material brittleness
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
Fire risk
Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Crushing force
Big blocks can crush fingers in a fraction of a second. Do not place your hand betwixt two attracting surfaces.
Operating temperature
Control the heat. Exposing the magnet to high heat will permanently weaken its properties and strength.
