💡 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!

Advantages as well as disadvantages of Nd2Fe14B magnets.
Strengths
- They retain magnetic properties for nearly ten years – the drop is just ~1% (based on simulations),
- Neodymium magnets remain remarkably resistant to magnetic field loss caused by external magnetic fields,
- In other words, due to the aesthetic layer of nickel, the element is aesthetically pleasing,
- Magnets exhibit huge magnetic induction on the active area,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- In view of the ability of precise forming and adaptation to individualized solutions, magnetic components can be created in a variety of geometric configurations, which makes them more universal,
- Significant place in modern technologies – they are used in HDD drives, electromotive mechanisms, medical devices, as well as complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We recommend a housing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, small components of these products are able to disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum magnetic pulling force – what it depends on?
- with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
- whose thickness is min. 10 mm
- with a surface cleaned and smooth
- without any clearance between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in neutral thermal conditions
Lifting capacity in practice – influencing factors
- Distance – existence of any layer (paint, tape, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is available only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin plate does not accept the full field, causing part of the power to be escaped to the other side.
- Plate material – mild steel attracts best. Alloy steels reduce magnetic properties and holding force.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate reduces the holding force.
Warnings
Permanent damage
Monitor thermal conditions. Heating the magnet to high heat will permanently weaken its magnetic structure and pulling force.
Fire risk
Combustion risk: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.
Risk of cracking
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets leads to them breaking into small pieces.
Immense force
Use magnets with awareness. Their huge power can shock even professionals. Plan your moves and respect their force.
Safe distance
Do not bring magnets near a purse, laptop, or TV. The magnetic field can permanently damage these devices and erase data from cards.
Avoid contact if allergic
Medical facts indicate that nickel (standard magnet coating) is a strong allergen. For allergy sufferers, refrain from direct skin contact or opt for versions in plastic housing.
Health Danger
Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Choking Hazard
NdFeB magnets are not suitable for play. Eating several magnets may result in them attracting across intestines, which poses a severe health hazard and necessitates immediate surgery.
Serious injuries
Risk of injury: The attraction force is so immense that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.
Compass and GPS
An intense magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Keep magnets near a device to prevent breaking the sensors.
