💡 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!

Pros as well as cons of rare earth magnets.
Benefits
- They retain attractive force for nearly ten years – the loss is just ~1% (in theory),
- Neodymium magnets are characterized by exceptionally resistant to loss of magnetic properties caused by external interference,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- Neodymium magnets deliver maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Thanks to the possibility of precise molding and adaptation to unique projects, neodymium magnets can be manufactured in a broad palette of shapes and sizes, which expands the range of possible applications,
- Universal use in high-tech industry – they are commonly used in data components, brushless drives, precision medical tools, as well as complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- We suggest cover - magnetic mount, due to difficulties in creating threads inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which gains importance in the context of child health protection. Additionally, small elements of these magnets are able to complicate diagnosis medical when they are in the body.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- with the application of a sheet made of special test steel, ensuring full magnetic saturation
- whose transverse dimension equals approx. 10 mm
- characterized by even structure
- under conditions of ideal adhesion (metal-to-metal)
- under perpendicular force vector (90-degree angle)
- at conditions approx. 20°C
Lifting capacity in real conditions – factors
- Gap between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Direction of force – maximum parameter is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Plate material – low-carbon steel attracts best. Higher carbon content lower magnetic permeability and lifting capacity.
- Smoothness – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Heat – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Warnings
Fire risk
Dust produced during cutting of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Immense force
Use magnets with awareness. Their huge power can shock even experienced users. Be vigilant and respect their power.
Eye protection
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets will cause them breaking into small pieces.
This is not a toy
NdFeB magnets are not intended for children. Swallowing several magnets may result in them connecting inside the digestive tract, which poses a critical condition and requires urgent medical intervention.
Thermal limits
Avoid heat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Bone fractures
Big blocks can crush fingers in a fraction of a second. Under no circumstances put your hand betwixt two strong magnets.
Skin irritation risks
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness occurs, immediately stop handling magnets and wear gloves.
Keep away from electronics
An intense magnetic field disrupts the functioning of magnetometers in phones and GPS navigation. Maintain magnets near a smartphone to prevent damaging the sensors.
Cards and drives
Data protection: Strong magnets can ruin payment cards and sensitive devices (heart implants, medical aids, mechanical watches).
Health Danger
Warning for patients: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.
