💡 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!

Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- They have unchanged lifting capacity, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
- They possess excellent resistance to weakening of magnetic properties as a result of external fields,
- In other words, due to the reflective surface of nickel, the element gains visual value,
- Magnetic induction on the surface of the magnet remains impressive,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of custom machining and adapting to specific applications,
- Key role in advanced technology sectors – they are commonly used in hard drives, electric drive systems, medical equipment, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in compact constructions
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in producing threads and complicated forms in magnets, we propose using a housing - magnetic mount.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small components of these magnets can complicate diagnosis medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a block made of structural steel, optimally conducting the magnetic field
- with a thickness no less than 10 mm
- characterized by lack of roughness
- without any air gap between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at temperature room level
Magnet lifting force in use – key factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Load vector – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Material composition – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
- Plate texture – ground elements ensure maximum contact, which increases force. Rough surfaces weaken the grip.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was measured using a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Safety rules for work with neodymium magnets
Warning for allergy sufferers
Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, avoid direct skin contact and select versions in plastic housing.
Caution required
Handle with care. Neodymium magnets act from a long distance and snap with huge force, often quicker than you can react.
Danger to pacemakers
For implant holders: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
Combustion hazard
Machining of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Keep away from computers
Intense magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Eye protection
Neodymium magnets are ceramic materials, which means they are very brittle. Impact of two magnets leads to them shattering into shards.
Thermal limits
Keep cool. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
Magnetic interference
Navigation devices and mobile phones are highly susceptible to magnetism. Direct contact with a strong magnet can ruin the sensors in your phone.
Do not give to children
NdFeB magnets are not toys. Swallowing several magnets can lead to them attracting across intestines, which constitutes a critical condition and necessitates urgent medical intervention.
Hand protection
Big blocks can break fingers in a fraction of a second. Never put your hand betwixt two strong magnets.
