💡 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 and weaknesses of rare earth magnets.
Advantages
- Their magnetic field remains stable, and after around ten years it drops only by ~1% (according to research),
- They feature excellent resistance to magnetism drop due to opposing magnetic fields,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Neodymium magnets ensure maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of exact creating as well as optimizing to specific conditions,
- Versatile presence in electronics industry – they serve a role in data components, brushless drives, medical devices, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in miniature devices
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing threads and complicated shapes in magnets, we recommend using casing - magnetic mechanism.
- Health risk to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum holding power of the magnet – what it depends on?
- on a block made of mild steel, optimally conducting the magnetic field
- whose thickness equals approx. 10 mm
- characterized by lack of roughness
- without any clearance between the magnet and steel
- during pulling in a direction perpendicular to the plane
- at room temperature
Determinants of lifting force in real conditions
- Distance – existence of foreign body (rust, tape, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – too thin plate does not close the flux, causing part of the flux to be wasted to the other side.
- Material type – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
- Base smoothness – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently damage 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 lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the holding force.
H&S for magnets
Caution required
Exercise caution. Rare earth magnets attract from a long distance and connect with massive power, often faster than you can move away.
Life threat
Individuals with a ICD have to maintain an absolute distance from magnets. The magnetism can interfere with the operation of the implant.
Combustion hazard
Machining of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Operating temperature
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Threat to navigation
Be aware: neodymium magnets generate a field that interferes with precision electronics. Keep a safe distance from your mobile, device, and navigation systems.
This is not a toy
These products are not intended for children. Eating a few magnets may result in them connecting inside the digestive tract, which constitutes a severe health hazard and requires immediate surgery.
Physical harm
Mind your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Skin irritation risks
Some people have a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact might lead to an allergic reaction. It is best to wear protective gloves.
Magnets are brittle
Despite metallic appearance, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
Data carriers
Data protection: Neodymium magnets can damage data carriers and delicate electronics (heart implants, hearing aids, timepieces).
