💡 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
- Their power remains stable, and after approximately ten years it drops only by ~1% (according to research),
- They have excellent resistance to magnetism drop due to opposing magnetic fields,
- The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the surface of the magnet turns out to be maximum,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures approaching 230°C and above...
- Thanks to modularity in forming and the capacity to adapt to individual projects,
- Versatile presence in advanced technology sectors – they are used in data components, electric motors, precision medical tools, also complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating nuts in the magnet and complicated shapes - recommended is casing - magnet mounting.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these devices are able to be problematic in diagnostics medical after entering the body.
- Due to expensive raw materials, their price is relatively high,
Lifting parameters
Maximum lifting capacity of the magnet – what it depends on?
- with the contact of a sheet made of low-carbon steel, ensuring maximum field concentration
- possessing a thickness of min. 10 mm to avoid saturation
- with a plane free of scratches
- with total lack of distance (without impurities)
- under vertical force direction (90-degree angle)
- at standard ambient temperature
Lifting capacity in real conditions – factors
- Clearance – existence of any layer (paint, dirt, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Steel thickness – too thin plate causes magnetic saturation, causing part of the flux to be wasted into the air.
- Material type – ideal substrate is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Surface condition – ground elements ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
- Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Safe handling of neodymium magnets
Crushing risk
Risk of injury: The pulling power is so great that it can cause hematomas, crushing, and broken bones. Use thick gloves.
Product not for children
Product intended for adults. Small elements pose a choking risk, leading to intestinal necrosis. Store out of reach of kids and pets.
Danger to pacemakers
Warning for patients: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.
Eye protection
Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Protect data
Data protection: Strong magnets can ruin payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).
Nickel coating and allergies
Some people experience a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Extended handling may cause skin redness. We recommend use protective gloves.
Keep away from electronics
A powerful magnetic field disrupts the functioning of compasses in phones and GPS navigation. Maintain magnets near a smartphone to prevent breaking the sensors.
Permanent damage
Control the heat. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.
Dust is flammable
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Powerful field
Use magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and do not underestimate their power.
