💡 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!

Strengths and weaknesses of Nd2Fe14B magnets.
Benefits
- They do not lose power, even over approximately ten years – the drop in lifting capacity is only ~1% (according to tests),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- Thanks to the smooth finish, the surface of Ni-Cu-Ni, gold-plated, or silver gives an aesthetic appearance,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to flexibility in forming and the capacity to adapt to specific needs,
- Universal use in electronics industry – they are utilized in magnetic memories, electric drive systems, medical devices, and modern systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength 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 stable to moisture, when using outdoors
- Limited possibility of producing nuts in the magnet and complex forms - preferred is cover - magnet mounting.
- Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Additionally, tiny parts of these products are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a block made of structural steel, effectively closing the magnetic flux
- with a thickness minimum 10 mm
- characterized by lack of roughness
- under conditions of gap-free contact (metal-to-metal)
- during detachment in a direction vertical to the mounting surface
- at conditions approx. 20°C
Magnet lifting force in use – key factors
- Air gap (between the magnet and the metal), as even a tiny distance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Material composition – not every steel reacts the same. High carbon content weaken the attraction effect.
- Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Thermal environment – heating the magnet results in weakening of induction. Check the thermal limit for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate reduces the load capacity.
Warnings
GPS Danger
Navigation devices and smartphones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can permanently damage the sensors in your phone.
Handling guide
Use magnets with awareness. Their powerful strength can shock even experienced users. Stay alert and respect their force.
Permanent damage
Control the heat. Exposing the magnet to high heat will permanently weaken its magnetic structure and strength.
Risk of cracking
Watch out for shards. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
ICD Warning
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Physical harm
Danger of trauma: The attraction force is so immense that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
No play value
Product intended for adults. Small elements pose a choking risk, leading to severe trauma. Keep out of reach of kids and pets.
Machining danger
Combustion risk: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.
Nickel allergy
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness occurs, cease working with magnets and use protective gear.
Electronic hazard
Avoid bringing magnets near a wallet, computer, or TV. The magnetism can destroy these devices and wipe information from cards.
