💡 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 and cons of neodymium magnets.
Advantages
- They do not lose magnetism, even after nearly 10 years – the drop in power is only ~1% (according to tests),
- They maintain their magnetic properties even under strong external field,
- Thanks to the shimmering finish, the surface of nickel, gold, or silver-plated gives an clean appearance,
- Magnetic induction on the working part of the magnet turns out to be extremely intense,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Thanks to the possibility of accurate molding and adaptation to specialized needs, neodymium magnets can be modeled in a variety of forms and dimensions, which expands the range of possible applications,
- Significant place in innovative solutions – they are commonly used in magnetic memories, electric drive systems, medical equipment, as well as complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 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, in case of application outdoors
- Limited possibility of creating threads in the magnet and complex shapes - recommended is cover - magnet mounting.
- Health risk resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Additionally, small components of these devices are able to be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum lifting force for a neodymium magnet – what contributes to it?
- on a plate made of mild steel, optimally conducting the magnetic field
- with a thickness minimum 10 mm
- with a surface perfectly flat
- under conditions of ideal adhesion (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Distance – existence of any layer (paint, tape, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Angle of force application – highest force is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material type – the best choice is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was determined using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
Precautions when working with neodymium magnets
Beware of splinters
NdFeB magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets will cause them shattering into small pieces.
Bone fractures
Big blocks can smash fingers in a fraction of a second. Do not place your hand between two attracting surfaces.
Magnetic interference
Navigation devices and smartphones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Conscious usage
Use magnets consciously. Their immense force can shock even professionals. Plan your moves and respect their force.
Fire risk
Mechanical processing of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Electronic devices
Do not bring magnets close to a purse, computer, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Power loss in heat
Keep cool. Neodymium magnets are sensitive to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Danger to the youngest
Product intended for adults. Small elements pose a choking risk, leading to serious injuries. Store away from children and animals.
Skin irritation risks
Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation appears, cease handling magnets and wear gloves.
Medical interference
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
