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 Nd2Fe14B magnets.
Strengths
- They do not lose strength, even during nearly 10 years – the decrease in lifting capacity is only ~1% (according to tests),
- They do not lose their magnetic properties even under strong external field,
- By covering with a lustrous coating of nickel, the element presents an professional look,
- The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to flexibility in shaping and the capacity to modify to complex applications,
- Universal use in high-tech industry – they serve a role in HDD drives, electromotive mechanisms, medical equipment, as well as multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Cons
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in strength. 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
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in producing threads and complex forms in magnets, we recommend using a housing - magnetic mechanism.
- Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these devices are able to disrupt the diagnostic process medical when they are in the body.
- With mass production the cost of neodymium magnets is economically unviable,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what it depends on?
- with the use of a yoke made of special test steel, guaranteeing full magnetic saturation
- whose transverse dimension reaches at least 10 mm
- characterized by smoothness
- without the slightest insulating layer between the magnet and steel
- under perpendicular force vector (90-degree angle)
- at temperature room level
Practical lifting capacity: influencing factors
- Distance – the presence of any layer (rust, dirt, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Load vector – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick steel does not accept the full field, causing part of the flux to be lost to the other side.
- Steel grade – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Temperature – temperature increase causes a temporary drop of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
GPS Danger
A strong magnetic field interferes with the operation of magnetometers in phones and navigation systems. Do not bring magnets near a smartphone to prevent damaging the sensors.
Pacemakers
For implant holders: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
Shattering risk
Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Conscious usage
Be careful. Neodymium magnets act from a long distance and snap with huge force, often quicker than you can react.
Choking Hazard
Neodymium magnets are not suitable for play. Eating a few magnets can lead to them attracting across intestines, which constitutes a severe health hazard and requires immediate surgery.
Power loss in heat
Control the heat. Exposing the magnet to high heat will permanently weaken its properties and strength.
Metal Allergy
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness happens, cease handling magnets and wear gloves.
Bodily injuries
Large magnets can break fingers in a fraction of a second. Never place your hand betwixt two attracting surfaces.
Keep away from computers
Avoid bringing magnets near a purse, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.
Do not drill into magnets
Machining of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
