💡 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!

Strengths and weaknesses of neodymium magnets.
Advantages
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (according to literature),
- They do not lose their magnetic properties even under close interference source,
- Thanks to the reflective finish, the plating of nickel, gold-plated, or silver gives an visually attractive appearance,
- Magnetic induction on the surface of the magnet turns out to be extremely intense,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Considering the ability of free molding and customization to unique requirements, magnetic components can be manufactured in a variety of forms and dimensions, which amplifies use scope,
- Fundamental importance in future technologies – they are utilized in mass storage devices, electromotive mechanisms, diagnostic systems, and multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Weaknesses
- To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- Due to limitations in producing nuts and complex shapes in magnets, we propose using a housing - magnetic mount.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Furthermore, small elements of these products can complicate diagnosis medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is economically unviable,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what it depends on?
- on a base made of structural steel, perfectly concentrating the magnetic flux
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an ground contact surface
- without the slightest air gap between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Clearance – the presence of any layer (paint, dirt, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may attract less.
- Smoothness – full contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Temperature influence – hot environment reduces magnetic field. Too high temperature can permanently damage the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
H&S for magnets
Health Danger
Warning for patients: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.
Demagnetization risk
Monitor thermal conditions. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.
Hand protection
Protect your hands. Two large magnets will snap together instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!
Machining danger
Drilling and cutting of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
This is not a toy
These products are not intended for children. Accidental ingestion of several magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and necessitates urgent medical intervention.
Immense force
Handle with care. Neodymium magnets attract from a long distance and snap with huge force, often quicker than you can react.
Allergic reactions
Certain individuals suffer from a contact allergy to Ni, which is the common plating for neodymium magnets. Frequent touching might lead to dermatitis. We recommend use safety gloves.
Magnets are brittle
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Electronic hazard
Avoid bringing magnets close to a wallet, laptop, or TV. The magnetism can destroy these devices and erase data from cards.
Impact on smartphones
Note: rare earth magnets generate a field that interferes with sensitive sensors. Maintain a safe distance from your phone, tablet, and navigation systems.
