💡 Guide: How to choose a decent magnet and not get ripped off?
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 rare earth magnets.
Advantages
- Their power is durable, and after approximately 10 years it drops only by ~1% (according to research),
- They have excellent resistance to magnetic field loss due to opposing magnetic fields,
- By applying a lustrous coating of nickel, the element gains an aesthetic look,
- Magnets are distinguished by extremely high magnetic induction on the surface,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Due to the possibility of accurate molding and adaptation to specialized projects, neodymium magnets can be created in a variety of shapes and sizes, which amplifies use scope,
- Significant place in innovative solutions – they are used in data components, electric motors, medical equipment, also industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of producing nuts in the magnet and complicated shapes - recommended is casing - magnet mounting.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these devices can disrupt the diagnostic process medical in case of swallowing.
- Due to complex production process, their price is higher than average,
Pull force analysis
Maximum holding power of the magnet – what affects it?
- using a sheet made of mild steel, acting as a circuit closing element
- with a thickness no less than 10 mm
- characterized by lack of roughness
- under conditions of gap-free contact (metal-to-metal)
- during detachment in a direction perpendicular to the mounting surface
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Steel grade – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
- Surface structure – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.
Lifting capacity was measured by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate reduces the load capacity.
Precautions when working with NdFeB magnets
Crushing risk
Watch your fingers. Two large magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Product not for children
Adult use only. Tiny parts can be swallowed, leading to serious injuries. Store away from kids and pets.
Safe operation
Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Permanent damage
Watch the temperature. Exposing the magnet above 80 degrees Celsius will ruin its properties and pulling force.
Cards and drives
Data protection: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, timepieces).
Allergic reactions
It is widely known that nickel (standard magnet coating) is a strong allergen. If you have an allergy, prevent touching magnets with bare hands or opt for encased magnets.
Dust is flammable
Dust generated during cutting of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Threat to navigation
A powerful magnetic field negatively affects the operation of magnetometers in phones and navigation systems. Keep magnets near a smartphone to avoid damaging the sensors.
ICD Warning
Individuals with a pacemaker must maintain an safe separation from magnets. The magnetic field can stop the operation of the implant.
Shattering risk
Protect your eyes. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.
