💡 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 as well as cons of neodymium magnets.
Advantages
- They have constant strength, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
- They are noted for resistance to demagnetization induced by external disturbances,
- In other words, due to the shiny layer of gold, the element looks attractive,
- Magnets have very high magnetic induction on the active area,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Considering the option of accurate shaping and adaptation to specialized projects, NdFeB magnets can be produced in a wide range of geometric configurations, which expands the range of possible applications,
- Versatile presence in future technologies – they find application in computer drives, brushless drives, medical equipment, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in miniature devices
Cons
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic mount, due to difficulties in producing threads inside the magnet and complicated shapes.
- Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, tiny parts of these devices can disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- with a thickness of at least 10 mm
- with an ideally smooth contact surface
- under conditions of gap-free contact (metal-to-metal)
- during detachment in a direction perpendicular to the mounting surface
- at ambient temperature room level
Determinants of lifting force in real conditions
- Gap (betwixt the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, rust or debris).
- Load vector – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick plate does not accept the full field, causing part of the power to be escaped into the air.
- Plate material – low-carbon steel attracts best. Alloy admixtures decrease magnetic properties and lifting capacity.
- Plate texture – ground elements guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
- Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
Shattering risk
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
Handling rules
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Fire warning
Drilling and cutting of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Protect data
Very strong magnetic fields can destroy records on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.
Avoid contact if allergic
Nickel alert: The Ni-Cu-Ni coating contains nickel. If redness appears, cease working with magnets and use protective gear.
Magnetic interference
A strong magnetic field negatively affects the operation of compasses in smartphones and navigation systems. Do not bring magnets near a smartphone to prevent damaging the sensors.
This is not a toy
Product intended for adults. Tiny parts can be swallowed, causing intestinal necrosis. Store out of reach of kids and pets.
Maximum temperature
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Medical interference
People with a heart stimulator should keep an absolute distance from magnets. The magnetic field can interfere with the functioning of the life-saving device.
Crushing force
Watch your fingers. Two powerful magnets will join immediately with a force of massive weight, destroying anything in their path. Be careful!
