💡 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!

Advantages as well as disadvantages of neodymium magnets.
Strengths
- They retain full power for nearly ten years – the drop is just ~1% (in theory),
- Neodymium magnets prove to be highly resistant to magnetic field loss caused by external magnetic fields,
- A magnet with a shiny gold surface has an effective appearance,
- Neodymium magnets deliver maximum magnetic induction on a small surface, which allows for strong attraction,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Possibility of custom shaping as well as optimizing to concrete needs,
- Key role in innovative solutions – they find application in data components, electric motors, advanced medical instruments, as well as modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in force. 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
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complicated shapes in magnets, we propose using cover - magnetic holder.
- Health risk to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these products are able to be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- using a sheet made of low-carbon steel, functioning as a ideal flux conductor
- whose thickness reaches at least 10 mm
- with an ideally smooth contact surface
- with direct contact (no coatings)
- for force acting at a right angle (in the magnet axis)
- in neutral thermal conditions
Lifting capacity in practice – influencing factors
- Distance (between the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to varnish, rust or debris).
- Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel type – mild steel attracts best. Higher carbon content decrease magnetic properties and lifting capacity.
- Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature influence – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.
Lifting capacity was measured with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Safe handling of NdFeB magnets
Medical implants
People with a pacemaker must keep an safe separation from magnets. The magnetism can stop the operation of the life-saving device.
Handling guide
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Magnetic interference
Be aware: neodymium magnets produce a field that confuses precision electronics. Keep a safe distance from your phone, tablet, and GPS.
Pinching danger
Big blocks can break fingers instantly. Under no circumstances put your hand betwixt two strong magnets.
Do not overheat magnets
Watch the temperature. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.
Product not for children
Always store magnets away from children. Choking hazard is significant, and the consequences of magnets connecting inside the body are very dangerous.
Do not drill into magnets
Drilling and cutting of neodymium magnets poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Beware of splinters
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.
Keep away from computers
Very strong magnetic fields can destroy records on credit cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
Allergic reactions
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, cease handling magnets and use protective gear.
