💡 Check why professionals choose Dhit over cheap substitutes
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 as well as disadvantages of neodymium magnets.
Benefits
- Their power is maintained, and after around 10 years it drops only by ~1% (according to research),
- They have excellent resistance to magnetism drop when exposed to external magnetic sources,
- In other words, due to the metallic surface of gold, the element is aesthetically pleasing,
- Magnets exhibit huge magnetic induction on the working surface,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Due to the possibility of accurate forming and customization to unique solutions, magnetic components can be modeled in a broad palette of shapes and sizes, which makes them more universal,
- Universal use in electronics industry – they serve a role in data components, electric motors, medical devices, as well as modern systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also increases their durability
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing threads and complicated shapes in magnets, we recommend using a housing - magnetic mount.
- Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- on a base made of mild steel, perfectly concentrating the magnetic field
- whose thickness is min. 10 mm
- with a plane perfectly flat
- without the slightest insulating layer between the magnet and steel
- under perpendicular force vector (90-degree angle)
- in stable room temperature
Determinants of lifting force in real conditions
- Gap (between the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (typically approx. 20-30% of nominal force).
- Steel thickness – insufficiently thick sheet does not accept the full field, causing part of the flux to be wasted into the air.
- Steel grade – the best choice is high-permeability steel. Cast iron may generate lower lifting capacity.
- Surface structure – the smoother and more polished the surface, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was determined by applying a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
Safe handling of NdFeB magnets
Bone fractures
Danger of trauma: The pulling power is so great that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Beware of splinters
Neodymium magnets are ceramic materials, which means they are very brittle. Collision of two magnets will cause them cracking into shards.
Threat to navigation
GPS units and smartphones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Life threat
For implant holders: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Conscious usage
Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.
This is not a toy
Strictly store magnets out of reach of children. Ingestion danger is high, and the effects of magnets connecting inside the body are very dangerous.
Threat to electronics
Do not bring magnets near a purse, laptop, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
Heat sensitivity
Avoid heat. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).
Warning for allergy sufferers
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, cease working with magnets and wear gloves.
Mechanical processing
Fire warning: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.
