💡 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!

Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- They retain magnetic properties for nearly ten years – the loss is just ~1% (according to analyses),
- Magnets perfectly protect themselves against demagnetization caused by ambient magnetic noise,
- Thanks to the shiny finish, the layer of nickel, gold-plated, or silver-plated gives an elegant appearance,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- In view of the possibility of accurate molding and adaptation to individualized projects, magnetic components can be produced in a variety of forms and dimensions, which increases their versatility,
- Huge importance in modern industrial fields – they serve a role in computer drives, electromotive mechanisms, medical equipment, as well as industrial machines.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Cons
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in realizing nuts and complex shapes in magnets, we propose using a housing - magnetic mount.
- Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Additionally, tiny parts of these magnets are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Best holding force of the magnet in ideal parameters – what it depends on?
- with the contact of a sheet made of special test steel, ensuring maximum field concentration
- with a thickness no less than 10 mm
- with a surface perfectly flat
- under conditions of gap-free contact (metal-to-metal)
- under axial force direction (90-degree angle)
- in temp. approx. 20°C
Practical aspects of lifting capacity – factors
- Clearance – existence of any layer (rust, dirt, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Base massiveness – too thin steel causes magnetic saturation, causing part of the power to be wasted into the air.
- Material composition – different alloys attracts identically. Alloy additives weaken the attraction effect.
- Surface condition – ground elements ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
- Temperature – heating the magnet results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate lowers the holding force.
Warnings
Handling guide
Handle magnets consciously. Their immense force can shock even professionals. Stay alert and do not underestimate their power.
Combustion hazard
Fire warning: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
Heat warning
Regular neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. The loss of strength is permanent.
Fragile material
Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
Warning for allergy sufferers
A percentage of the population have a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Extended handling might lead to a rash. We strongly advise use protective gloves.
Threat to navigation
A strong magnetic field interferes with the functioning of compasses in phones and navigation systems. Do not bring magnets near a smartphone to avoid breaking the sensors.
Electronic devices
Intense magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
Danger to pacemakers
Life threat: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Keep away from children
These products are not toys. Swallowing several magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and requires urgent medical intervention.
Serious injuries
Risk of injury: The pulling power is so great that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
