💡 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.
Strengths
- They do not lose power, even during nearly 10 years – the decrease in lifting capacity is only ~1% (based on measurements),
- They have excellent resistance to magnetic field loss due to external fields,
- The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
- Thanks to the option of flexible molding and customization to individualized needs, magnetic components can be produced in a wide range of forms and dimensions, which expands the range of possible applications,
- Wide application in future technologies – they are used in magnetic memories, electric drive systems, diagnostic systems, as well as technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- At very strong impacts they can break, therefore we advise placing them in strong housings. 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 power. Often, when the temperature exceeds 80°C, their power 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 advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- We suggest a housing - magnetic mount, due to difficulties in creating threads inside the magnet and complicated forms.
- Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these devices 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
Holding force characteristics
Detachment force of the magnet in optimal conditions – what affects it?
- on a base made of mild steel, perfectly concentrating the magnetic field
- possessing a thickness of min. 10 mm to avoid saturation
- with an ideally smooth contact surface
- without the slightest clearance between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at room temperature
Lifting capacity in practice – influencing factors
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Metal type – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
- Base smoothness – the more even the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Thermal factor – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the holding force is lower. In addition, even a slight gap between the magnet and the plate lowers the lifting capacity.
Safe handling of neodymium magnets
Threat to navigation
Navigation devices and smartphones are highly sensitive to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Beware of splinters
Watch out for shards. Magnets can fracture upon violent connection, ejecting shards into the air. Eye protection is mandatory.
Product not for children
Product intended for adults. Small elements pose a choking risk, leading to serious injuries. Store out of reach of children and animals.
Life threat
Warning for patients: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or request help to work with the magnets.
Caution required
Handle magnets consciously. Their huge power can surprise even professionals. Be vigilant and respect their power.
Dust explosion hazard
Dust produced during grinding of magnets is combustible. Do not drill into magnets unless you are an expert.
Finger safety
Mind your fingers. Two large magnets will snap together immediately with a force of massive weight, destroying anything in their path. Be careful!
Safe distance
Equipment safety: Strong magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
Demagnetization risk
Do not overheat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
Metal Allergy
It is widely known that the nickel plating (standard magnet coating) is a strong allergen. For allergy sufferers, refrain from touching magnets with bare hands or select encased magnets.
