💡 Check why professionals choose Dhit over cheap substitutes
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
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
- They are resistant to demagnetization induced by external field influence,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the working part of the magnet remains maximum,
- 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 precise modeling as well as adapting to complex conditions,
- Fundamental importance in future technologies – they find application in mass storage devices, drive modules, medical equipment, as well as multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Weaknesses
- Brittleness 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
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complicated shapes in magnets, we recommend using casing - magnetic holder.
- Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these devices can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Magnetic strength at its maximum – what it depends on?
- with the use of a sheet made of special test steel, ensuring maximum field concentration
- possessing a thickness of at least 10 mm to ensure full flux closure
- with an ideally smooth contact surface
- with zero gap (no impurities)
- for force applied at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Air gap (between the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, rust or dirt).
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (typically approx. 20-30% of maximum force).
- Plate thickness – too thin sheet does not close the flux, causing part of the power to be escaped into the air.
- Steel grade – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
- Base smoothness – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Temperature – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Safety rules for work with neodymium magnets
Allergic reactions
It is widely known that nickel (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid touching magnets with bare hands and choose coated magnets.
Physical harm
Risk of injury: The pulling power is so great that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.
Safe distance
Do not bring magnets close to a purse, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.
Caution required
Use magnets consciously. Their immense force can shock even professionals. Stay alert and do not underestimate their force.
Heat sensitivity
Keep cool. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, look for HT versions (H, SH, UH).
ICD Warning
Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Protective goggles
Despite metallic appearance, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Danger to the youngest
These products are not toys. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which poses a critical condition and requires urgent medical intervention.
GPS and phone interference
A powerful magnetic field disrupts the operation of magnetometers in phones and navigation systems. Do not bring magnets near a device to avoid breaking the sensors.
Flammability
Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
