💡 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 neodymium magnets.
Advantages
- They have stable power, and over around ten years their attraction force decreases symbolically – ~1% (in testing),
- They do not lose their magnetic properties even under close interference source,
- A magnet with a metallic silver surface has an effective appearance,
- Neodymium magnets create maximum magnetic induction on a small surface, which allows for strong attraction,
- 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 freedom in designing and the capacity to customize to individual projects,
- Universal use in future technologies – they are commonly used in data components, drive modules, medical equipment, and complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Disadvantages
- They are fragile upon heavy 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
- Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing nuts and complex shapes in magnets, we propose using cover - magnetic mechanism.
- Health risk related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these products can complicate diagnosis medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Detachment force of the magnet in optimal conditions – what affects it?
- on a base made of structural steel, optimally conducting the magnetic field
- possessing a thickness of min. 10 mm to avoid saturation
- characterized by smoothness
- with direct contact (no impurities)
- during detachment in a direction perpendicular to the plane
- at conditions approx. 20°C
What influences lifting capacity in practice
- Distance (betwixt the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
H&S for magnets
Eye protection
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
Fire warning
Dust created during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
This is not a toy
NdFeB magnets are not suitable for play. Accidental ingestion of several magnets may result in them attracting across intestines, which poses a direct threat to life and requires immediate surgery.
Finger safety
Pinching hazard: The attraction force is so great that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.
Nickel coating and allergies
Some people suffer from a hypersensitivity to nickel, which is the standard coating for NdFeB magnets. Frequent touching might lead to a rash. It is best to use protective gloves.
Protect data
Data protection: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Permanent damage
Do not overheat. Neodymium magnets are sensitive to heat. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Compass and GPS
Navigation devices and smartphones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Do not underestimate power
Exercise caution. Rare earth magnets attract from a distance and snap with huge force, often faster than you can move away.
Life threat
For implant holders: Strong magnetic fields disrupt electronics. Maintain at least 30 cm distance or request help to work with the magnets.
