💡 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!

Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They retain full power for almost ten years – the loss is just ~1% (according to analyses),
- They maintain their magnetic properties even under strong external field,
- A magnet with a metallic nickel surface has better aesthetics,
- Neodymium magnets generate maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of accurate forming as well as adapting to defined requirements,
- Wide application in future technologies – they are used in HDD drives, electromotive mechanisms, medical equipment, as well as modern systems.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Limitations
- To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of creating nuts in the magnet and complicated shapes - preferred is cover - magnet mounting.
- Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical in case of swallowing.
- With mass production the cost of neodymium magnets is a challenge,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what affects it?
- with the application of a sheet made of low-carbon steel, ensuring full magnetic saturation
- with a thickness minimum 10 mm
- with a surface perfectly flat
- with direct contact (no paint)
- for force applied at a right angle (pull-off, not shear)
- at room temperature
Key elements affecting lifting force
- Distance (betwixt the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Steel grade – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate decreases the holding force.
Precautions when working with neodymium magnets
Permanent damage
Control the heat. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.
Magnets are brittle
Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Crushing risk
Protect your hands. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Danger to pacemakers
Warning for patients: Powerful magnets affect medical devices. Maintain at least 30 cm distance or request help to handle the magnets.
No play value
Neodymium magnets are not intended for children. Eating multiple magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and necessitates immediate surgery.
GPS Danger
A powerful magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Keep magnets close to a smartphone to avoid breaking the sensors.
Powerful field
Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Think ahead.
Dust explosion hazard
Powder generated during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Threat to electronics
Avoid bringing magnets close to a purse, laptop, or TV. The magnetic field can permanently damage these devices and erase data from cards.
Nickel coating and allergies
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, cease handling magnets and use protective gear.
