💡 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 and cons of neodymium magnets.
Benefits
- They retain full power for nearly 10 years – the loss is just ~1% (based on simulations),
- Magnets perfectly protect themselves against demagnetization caused by external fields,
- The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Neodymium magnets generate maximum magnetic induction on a contact point, which allows for strong attraction,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Possibility of precise shaping and adapting to precise applications,
- Universal use in electronics industry – they are used in data components, electromotive mechanisms, medical equipment, and other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- At strong impacts they can crack, therefore we advise 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 recommend our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in creating nuts and complicated forms in magnets, we recommend using casing - magnetic mechanism.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, tiny parts of these products can be problematic in diagnostics medical when they are in the body.
- Due to complex production process, their price is relatively high,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what it depends on?
- on a plate made of mild steel, perfectly concentrating the magnetic field
- with a thickness of at least 10 mm
- with an ideally smooth contact surface
- without the slightest insulating layer between the magnet and steel
- under perpendicular force vector (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Gap between surfaces – every millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Base massiveness – too thin sheet does not accept the full field, causing part of the flux to be escaped into the air.
- Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, however under shearing force the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet and the plate decreases the holding force.
Safety rules for work with NdFeB magnets
Allergic reactions
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness appears, immediately stop handling magnets and use protective gear.
ICD Warning
Life threat: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Heat sensitivity
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. The loss of strength is permanent.
Crushing risk
Mind your fingers. Two large magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Do not drill into magnets
Dust generated during cutting of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Risk of cracking
Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Respect the power
Handle magnets with awareness. Their huge power can shock even experienced users. Stay alert and do not underestimate their force.
Magnetic media
Data protection: Strong magnets can ruin data carriers and delicate electronics (heart implants, medical aids, mechanical watches).
Compass and GPS
Remember: rare earth magnets produce a field that disrupts precision electronics. Maintain a safe distance from your mobile, tablet, and GPS.
Choking Hazard
NdFeB magnets are not toys. Accidental ingestion of several magnets can lead to them attracting across intestines, which poses a critical condition and necessitates urgent medical intervention.
