💡 Guide: How to choose a decent magnet and not get ripped off?
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!

Pros as well as cons of Nd2Fe14B magnets.
Benefits
- Their strength is maintained, and after around 10 years it drops only by ~1% (theoretically),
- They are noted for resistance to demagnetization induced by external magnetic fields,
- The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Neodymium magnets create maximum magnetic induction on a contact point, which allows for strong attraction,
- 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...
- In view of the potential of accurate shaping and adaptation to unique requirements, neodymium magnets can be produced in a variety of forms and dimensions, which amplifies use scope,
- Key role in electronics industry – they are commonly used in magnetic memories, brushless drives, medical equipment, also industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- We suggest a housing - magnetic holder, due to difficulties in creating nuts inside the magnet and complicated forms.
- Health risk resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that small elements of these magnets can be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Best holding force of the magnet in ideal parameters – what contributes to it?
- using a sheet made of high-permeability steel, functioning as a ideal flux conductor
- possessing a massiveness of minimum 10 mm to avoid saturation
- with a surface perfectly flat
- with direct contact (no impurities)
- during detachment in a direction perpendicular to the plane
- in neutral thermal conditions
What influences lifting capacity in practice
- Distance (betwixt the magnet and the metal), as even a tiny distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, rust or debris).
- Direction of force – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Steel grade – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
- Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Choking Hazard
Neodymium magnets are not toys. Accidental ingestion of multiple magnets can lead to them connecting inside the digestive tract, which poses a critical condition and requires immediate surgery.
Nickel allergy
Studies show that nickel (standard magnet coating) is a common allergen. If you have an allergy, prevent touching magnets with bare hands and opt for coated magnets.
Handling rules
Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Mechanical processing
Powder produced during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.
Magnets are brittle
NdFeB magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets will cause them breaking into shards.
Hand protection
Mind your fingers. Two large magnets will snap together instantly with a force of massive weight, crushing anything in their path. Be careful!
Maximum temperature
Do not overheat. NdFeB magnets are susceptible to heat. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
Data carriers
Intense magnetic fields can destroy records on payment cards, hard drives, and storage devices. Stay away of at least 10 cm.
Warning for heart patients
Warning for patients: Powerful magnets affect electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
GPS Danger
A powerful magnetic field interferes with the operation of magnetometers in phones and navigation systems. Maintain magnets close to a device to avoid breaking the sensors.
