💡 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!

Pros and cons of Nd2Fe14B magnets.
Pros
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- They do not lose their magnetic properties even under close interference source,
- A magnet with a shiny silver surface has better aesthetics,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- 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 constructing and the ability to modify to unusual requirements,
- Universal use in modern industrial fields – they are used in computer drives, drive modules, diagnostic systems, also modern systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also raises 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.
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of making threads in the magnet and complicated shapes - preferred is a housing - mounting mechanism.
- Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- with the use of a yoke made of low-carbon steel, ensuring full magnetic saturation
- with a thickness of at least 10 mm
- characterized by smoothness
- with total lack of distance (no impurities)
- during pulling in a direction vertical to the plane
- at temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet holds much less (typically approx. 20-30% of maximum force).
- Base massiveness – insufficiently thick steel causes magnetic saturation, causing part of the power to be escaped into the air.
- Metal type – not every steel attracts identically. High carbon content weaken the attraction effect.
- Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Safe handling of neodymium magnets
Magnet fragility
Watch out for shards. Magnets can fracture upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Cards and drives
Intense magnetic fields can erase data on payment cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
Medical implants
Individuals with a pacemaker have to maintain an safe separation from magnets. The magnetic field can interfere with the operation of the life-saving device.
Do not overheat magnets
Monitor thermal conditions. Exposing the magnet to high heat will destroy its magnetic structure and strength.
Pinching danger
Risk of injury: The attraction force is so great that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Threat to navigation
Remember: neodymium magnets produce a field that confuses precision electronics. Maintain a safe distance from your mobile, device, and GPS.
Adults only
Only for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Keep out of reach of children and animals.
Nickel coating and allergies
Studies show that nickel (the usual finish) is a potent allergen. For allergy sufferers, prevent touching magnets with bare hands and opt for versions in plastic housing.
Do not underestimate power
Handle magnets with awareness. Their huge power can surprise even experienced users. Be vigilant and do not underestimate their force.
Dust explosion hazard
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
