💡 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 and cons of Nd2Fe14B magnets.
Advantages
- They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- A magnet with a shiny gold surface is more attractive,
- Neodymium magnets ensure maximum magnetic induction on a contact point, which increases force concentration,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
- Due to the ability of accurate shaping and adaptation to unique requirements, NdFeB magnets can be modeled in a variety of geometric configurations, which increases their versatility,
- Versatile presence in modern industrial fields – they serve a role in mass storage devices, motor assemblies, medical equipment, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in compact constructions
Cons
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases 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 force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in creating nuts and complicated forms in magnets, we propose using cover - magnetic holder.
- Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Furthermore, small elements of these devices are able to be problematic in diagnostics medical after entering the body.
- Due to neodymium price, their price is higher than average,
Lifting parameters
Maximum lifting capacity of the magnet – what it depends on?
- with the contact of a yoke made of special test steel, guaranteeing maximum field concentration
- whose thickness equals approx. 10 mm
- with an polished contact surface
- without any air gap between the magnet and steel
- during pulling in a direction perpendicular to the mounting surface
- at temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Base massiveness – insufficiently thick sheet does not accept the full field, causing part of the power to be escaped to the other side.
- Metal type – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
- Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- 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 checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.
Warnings
Threat to navigation
Navigation devices and mobile phones are highly susceptible to magnetism. Direct contact with a strong magnet can permanently damage the sensors in your phone.
Dust explosion hazard
Drilling and cutting of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Crushing force
Big blocks can crush fingers in a fraction of a second. Never place your hand betwixt two strong magnets.
Do not overheat magnets
Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
Pacemakers
Patients with a pacemaker should keep an safe separation from magnets. The magnetism can disrupt the functioning of the implant.
Fragile material
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Swallowing risk
Absolutely store magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are fatal.
Allergy Warning
Studies show that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and choose coated magnets.
Safe distance
Do not bring magnets close to a purse, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.
Caution required
Be careful. Rare earth magnets attract from a long distance and connect with massive power, often quicker than you can react.
