💡 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!

Strengths as well as weaknesses of rare earth magnets.
Benefits
- Their magnetic field is durable, and after approximately ten years it drops only by ~1% (theoretically),
- They maintain their magnetic properties even under external field action,
- Thanks to the reflective finish, the surface of nickel, gold, or silver-plated gives an aesthetic appearance,
- They feature high magnetic induction at the operating surface, which affects their effectiveness,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Possibility of exact machining and adjusting to atypical applications,
- Versatile presence in high-tech industry – they are used in HDD drives, electromotive mechanisms, diagnostic systems, also other advanced devices.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Due to limitations in creating threads and complicated shapes in magnets, we recommend using cover - magnetic mount.
- Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these products can complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Magnetic strength at its maximum – what it depends on?
- using a base made of mild steel, acting as a magnetic yoke
- with a cross-section no less than 10 mm
- with a plane free of scratches
- without any clearance between the magnet and steel
- during pulling in a direction vertical to the plane
- in neutral thermal conditions
Determinants of lifting force in real conditions
- Distance – existence of foreign body (rust, dirt, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
- Material composition – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
- Plate texture – ground elements ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
- Heat – 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 was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet’s surface and the plate reduces the holding force.
Safe handling of NdFeB magnets
Do not drill into magnets
Machining of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Do not give to children
Adult use only. Tiny parts can be swallowed, leading to serious injuries. Keep out of reach of kids and pets.
Power loss in heat
Do not overheat. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Precision electronics
An intense magnetic field interferes with the operation of magnetometers in phones and navigation systems. Maintain magnets near a device to prevent breaking the sensors.
ICD Warning
Patients with a heart stimulator should keep an absolute distance from magnets. The magnetism can interfere with the functioning of the life-saving device.
Do not underestimate power
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
Physical harm
Large magnets can crush fingers in a fraction of a second. Do not put your hand betwixt two attracting surfaces.
Fragile material
Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.
Nickel allergy
Some people suffer from a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Frequent touching might lead to a rash. We suggest wear protective gloves.
Electronic hazard
Avoid bringing magnets near a wallet, laptop, or screen. The magnetism can permanently damage these devices and wipe information from cards.
