💡 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 as well as weaknesses of neodymium magnets.
Benefits
- They retain full power for almost 10 years – the drop is just ~1% (according to analyses),
- They possess excellent resistance to magnetic field loss as a result of external fields,
- Thanks to the metallic finish, the plating of Ni-Cu-Ni, gold-plated, or silver-plated gives an clean appearance,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to modularity in designing and the ability to customize to specific needs,
- Huge importance in electronics industry – they are commonly used in mass storage devices, drive modules, diagnostic systems, as well as multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- 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 recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Limited ability of creating threads in the magnet and complex forms - preferred is cover - magnet mounting.
- Health risk related to microscopic parts of magnets are risky, if swallowed, which becomes key in the context of child health protection. Furthermore, small components of these products are able to be problematic in diagnostics 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
Maximum magnetic pulling force – what it depends on?
- using a sheet made of low-carbon steel, serving as a magnetic yoke
- with a cross-section minimum 10 mm
- with a surface free of scratches
- under conditions of ideal adhesion (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Key elements affecting lifting force
- Distance – existence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
- Steel grade – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Smoothness – full contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet and the plate lowers the load capacity.
Safety rules for work with neodymium magnets
Nickel allergy
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If redness occurs, cease working with magnets and wear gloves.
Life threat
Warning for patients: Strong magnetic fields affect electronics. Keep minimum 30 cm distance or request help to handle the magnets.
Fire warning
Machining of neodymium magnets carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Physical harm
Risk of injury: The pulling power is so great that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Shattering risk
Beware of splinters. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Conscious usage
Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Compass and GPS
Be aware: neodymium magnets generate a field that confuses precision electronics. Keep a safe distance from your mobile, tablet, and navigation systems.
Danger to the youngest
Always store magnets out of reach of children. Choking hazard is high, and the consequences of magnets clamping inside the body are very dangerous.
Operating temperature
Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Threat to electronics
Device Safety: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).
