💡 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 as well as cons of rare earth magnets.
Pros
- Their power is maintained, and after around ten years it drops only by ~1% (according to research),
- Neodymium magnets are characterized by highly resistant to magnetic field loss caused by magnetic disturbances,
- Thanks to the smooth finish, the plating of nickel, gold, or silver-plated gives an visually attractive appearance,
- Magnetic induction on the working layer of the magnet turns out to be strong,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Possibility of precise shaping as well as adapting to complex conditions,
- Huge importance in modern technologies – they find application in data components, electromotive mechanisms, medical devices, also multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited ability of making nuts in the magnet and complicated shapes - preferred is a housing - magnetic holder.
- Health risk resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child safety. Additionally, small components of these magnets can be problematic in diagnostics medical when they are in the body.
- Due to complex production process, their price is relatively high,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what it depends on?
- with the use of a yoke made of low-carbon steel, ensuring full magnetic saturation
- possessing a massiveness of minimum 10 mm to avoid saturation
- characterized by smoothness
- under conditions of gap-free contact (surface-to-surface)
- during pulling in a direction vertical to the plane
- in stable room temperature
Determinants of practical lifting force of a magnet
- Air gap (betwixt the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, corrosion or debris).
- Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Alloy admixtures decrease magnetic permeability and lifting capacity.
- Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature influence – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was measured by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet’s surface and the plate reduces the holding force.
Safety rules for work with neodymium magnets
Handling rules
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Bone fractures
Large magnets can break fingers in a fraction of a second. Under no circumstances place your hand between two strong magnets.
Magnetic media
Very strong magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Risk of cracking
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Danger to pacemakers
Patients with a heart stimulator should maintain an large gap from magnets. The magnetism can disrupt the functioning of the life-saving device.
Dust explosion hazard
Fire warning: Neodymium dust is explosive. Do not process magnets without safety gear as this risks ignition.
Nickel allergy
Some people suffer from a hypersensitivity to nickel, which is the common plating for NdFeB magnets. Prolonged contact can result in an allergic reaction. We strongly advise use protective gloves.
This is not a toy
Strictly keep magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are very dangerous.
Precision electronics
GPS units and smartphones are extremely susceptible to magnetism. Direct contact with a strong magnet can ruin the sensors in your phone.
Thermal limits
Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. This process is irreversible.
