💡 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 Nd2Fe14B magnets.
Pros
- They retain magnetic properties for around ten years – the loss is just ~1% (according to analyses),
- They have excellent resistance to weakening of magnetic properties due to opposing magnetic fields,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Neodymium magnets create maximum magnetic induction on a small surface, which allows for strong attraction,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- In view of the option of accurate shaping and customization to custom solutions, neodymium magnets can be modeled in a broad palette of forms and dimensions, which expands the range of possible applications,
- Fundamental importance in innovative solutions – they are utilized in magnetic memories, electric drive systems, advanced medical instruments, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in compact constructions
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also raises 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
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating threads and complex forms in magnets, we propose using cover - magnetic mechanism.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Furthermore, small elements of these devices can disrupt the diagnostic process medical when they are in the body.
- With large orders the cost of neodymium magnets can be a barrier,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- using a sheet made of high-permeability steel, functioning as a circuit closing element
- possessing a thickness of minimum 10 mm to avoid saturation
- with an ideally smooth contact surface
- with direct contact (no paint)
- for force applied at a right angle (pull-off, not shear)
- at temperature room level
Practical aspects of lifting capacity – factors
- Distance – the presence of foreign body (rust, dirt, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Material type – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
- Surface quality – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet and the plate lowers the lifting capacity.
Warnings
Eye protection
Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Threat to navigation
Note: neodymium magnets generate a field that confuses precision electronics. Maintain a separation from your mobile, device, and navigation systems.
Health Danger
Patients with a heart stimulator should keep an absolute distance from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Choking Hazard
Always store magnets away from children. Choking hazard is significant, and the effects of magnets clamping inside the body are life-threatening.
Threat to electronics
Do not bring magnets close to a purse, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.
Do not drill into magnets
Powder produced during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Nickel allergy
It is widely known that nickel (standard magnet coating) is a common allergen. If you have an allergy, avoid direct skin contact or choose versions in plastic housing.
Power loss in heat
Avoid heat. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Pinching danger
Large magnets can smash fingers in a fraction of a second. Do not put your hand between two strong magnets.
Respect the power
Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
