💡 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!

Strengths and weaknesses of rare earth magnets.
Advantages
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
- Neodymium magnets prove to be highly resistant to demagnetization caused by external magnetic fields,
- The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnets are distinguished by extremely high magnetic induction on the surface,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of accurate creating and optimizing to atypical requirements,
- Huge importance in modern technologies – they are used in HDD drives, electric drive systems, medical devices, as well as other advanced devices.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength 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
- They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic holder, due to difficulties in creating nuts inside the magnet and complicated shapes.
- Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these products can complicate diagnosis medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Best holding force of the magnet in ideal parameters – what affects it?
- using a sheet made of high-permeability steel, serving as a magnetic yoke
- whose thickness is min. 10 mm
- with a plane perfectly flat
- with total lack of distance (without impurities)
- during detachment in a direction perpendicular to the mounting surface
- at room temperature
Determinants of practical lifting force of a magnet
- Gap (between the magnet and the metal), because even a very small distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Plate thickness – insufficiently thick sheet does not accept the full field, causing part of the flux to be lost into the air.
- Chemical composition of the base – mild steel gives the best results. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Surface structure – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Temperature influence – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was assessed with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Allergy Warning
Some people have a contact allergy to nickel, which is the standard coating for neodymium magnets. Prolonged contact might lead to skin redness. We strongly advise use safety gloves.
Fire warning
Machining of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Protect data
Avoid bringing magnets near a purse, laptop, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
Do not give to children
NdFeB magnets are not toys. Accidental ingestion of multiple magnets may result in them connecting inside the digestive tract, which constitutes a severe health hazard and requires urgent medical intervention.
Power loss in heat
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Powerful field
Be careful. Rare earth magnets act from a long distance and snap with massive power, often faster than you can move away.
Beware of splinters
Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
GPS Danger
A strong magnetic field negatively affects the functioning of compasses in phones and navigation systems. Keep magnets near a device to prevent damaging the sensors.
Life threat
Medical warning: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Serious injuries
Mind your fingers. Two large magnets will join immediately with a force of massive weight, destroying anything in their path. Be careful!
