💡 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 Nd2Fe14B magnets.
Pros
- They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
- Neodymium magnets are characterized by highly resistant to demagnetization caused by external magnetic fields,
- A magnet with a metallic nickel surface has an effective appearance,
- Magnets are characterized by exceptionally strong 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 shape) at temperatures up to 230°C and above...
- Due to the option of accurate shaping and adaptation to individualized needs, neodymium magnets can be manufactured in a wide range of geometric configurations, which expands the range of possible applications,
- Huge importance in modern industrial fields – they are utilized in mass storage devices, brushless drives, precision medical tools, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in small systems
Disadvantages
- At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating threads and complicated shapes in magnets, we recommend using a housing - magnetic mount.
- Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. Furthermore, tiny parts of these devices can disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what it depends on?
- using a plate made of high-permeability steel, serving as a circuit closing element
- possessing a thickness of at least 10 mm to avoid saturation
- characterized by even structure
- with direct contact (no impurities)
- for force applied at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Air gap (between the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material composition – different alloys reacts the same. Alloy additives weaken the attraction effect.
- Smoothness – ideal contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal environment – heating the magnet causes a temporary drop of force. Check the maximum operating temperature for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
H&S for magnets
Crushing force
Watch your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing anything in their path. Be careful!
Risk of cracking
Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Keep away from children
Neodymium magnets are not toys. Eating multiple magnets may result in them attracting across intestines, which constitutes a severe health hazard and necessitates urgent medical intervention.
Handling rules
Exercise caution. Neodymium magnets attract from a long distance and snap with huge force, often faster than you can react.
Health Danger
Patients with a pacemaker have to keep an absolute distance from magnets. The magnetic field can interfere with the operation of the implant.
Data carriers
Powerful magnetic fields can destroy records on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.
Allergy Warning
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, cease handling magnets and wear gloves.
Permanent damage
Regular neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. This process is irreversible.
Fire risk
Fire warning: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
Threat to navigation
GPS units and smartphones are highly sensitive to magnetism. Close proximity with a strong magnet can permanently damage the internal compass in your phone.
