💡 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 neodymium magnets.
Strengths
- They do not lose magnetism, even during around ten years – the decrease in power is only ~1% (theoretically),
- Magnets very well defend themselves against demagnetization caused by ambient magnetic noise,
- By using a decorative layer of gold, the element acquires an professional look,
- Magnets have extremely high magnetic induction on the outer layer,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures approaching 230°C and above...
- Thanks to modularity in forming and the capacity to customize to individual projects,
- Key role in advanced technology sectors – they find application in data components, electric drive systems, medical devices, also industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and 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 resistant to moisture, when using outdoors
- Due to limitations in producing nuts and complex forms in magnets, we propose using a housing - magnetic mount.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these products are able to complicate diagnosis medical after entering 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
Magnetic strength at its maximum – what it depends on?
- on a plate made of mild steel, optimally conducting the magnetic field
- whose thickness is min. 10 mm
- with a surface cleaned and smooth
- without any air gap between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Air gap (betwixt the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Load vector – maximum parameter is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
- Metal type – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
- Surface structure – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, in contrast under parallel forces the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Safe handling of NdFeB magnets
Warning for heart patients
Individuals with a pacemaker have to keep an large gap from magnets. The magnetism can interfere with the operation of the life-saving device.
Do not drill into magnets
Machining of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
No play value
Product intended for adults. Small elements can be swallowed, leading to severe trauma. Keep out of reach of children and animals.
Data carriers
Avoid bringing magnets near a wallet, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.
Fragile material
Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Conscious usage
Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Think ahead.
Maximum temperature
Regular neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.
Crushing risk
Risk of injury: The attraction force is so great that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
Nickel allergy
Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, cease working with magnets and use protective gear.
Compass and GPS
Note: rare earth magnets produce a field that confuses precision electronics. Keep a safe distance from your mobile, device, and GPS.
