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.
Pros
- Their power is durable, and after approximately ten years it decreases only by ~1% (according to research),
- Neodymium magnets remain highly resistant to magnetic field loss caused by magnetic disturbances,
- The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to look better,
- Magnets have excellent magnetic induction on the working surface,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of individual machining as well as adapting to precise requirements,
- Significant place in future technologies – they find application in magnetic memories, brushless drives, precision medical tools, also other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures 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 immune to moisture, when using outdoors
- We recommend casing - magnetic mount, due to difficulties in creating threads inside the magnet and complicated shapes.
- Health risk resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these products are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Maximum magnetic pulling force – what it depends on?
- using a sheet made of high-permeability steel, serving as a circuit closing element
- with a thickness minimum 10 mm
- with a plane perfectly flat
- under conditions of ideal adhesion (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Distance – existence of any layer (paint, tape, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Metal type – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
- Surface condition – smooth surfaces ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined using a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
Safe handling of NdFeB magnets
Keep away from children
Product intended for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Keep out of reach of kids and pets.
Allergic reactions
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, cease working with magnets and wear gloves.
Cards and drives
Do not bring magnets near a wallet, computer, or TV. The magnetic field can destroy these devices and erase data from cards.
Serious injuries
Protect your hands. Two powerful magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
ICD Warning
Life threat: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Risk of cracking
NdFeB magnets are sintered ceramics, meaning they are very brittle. Collision of two magnets leads to them breaking into shards.
Fire warning
Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.
Respect the power
Before starting, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Operating temperature
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
Phone sensors
Note: rare earth magnets produce a field that interferes with precision electronics. Maintain a separation from your phone, device, and GPS.
