💡 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 as well as cons of Nd2Fe14B magnets.
Strengths
- Their magnetic field remains stable, and after approximately ten years it drops only by ~1% (theoretically),
- Neodymium magnets are remarkably resistant to loss of magnetic properties caused by external field sources,
- Thanks to the shiny finish, the layer of nickel, gold, or silver gives an aesthetic appearance,
- Neodymium magnets create maximum magnetic induction on a their surface, which ensures high operational effectiveness,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Possibility of detailed forming as well as adapting to precise needs,
- Significant place in modern industrial fields – they find application in mass storage devices, electric motors, precision medical tools, and other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets experience 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
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- We suggest a housing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complex forms.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. Additionally, small components of these products can disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price is higher than average,
Lifting parameters
Magnetic strength at its maximum – what contributes to it?
- on a block made of mild steel, perfectly concentrating the magnetic field
- with a cross-section no less than 10 mm
- with a surface cleaned and smooth
- under conditions of no distance (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Distance (betwixt the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Material type – ideal substrate is high-permeability steel. Hardened steels may attract less.
- Plate texture – ground elements ensure maximum contact, which improves force. Uneven metal weaken the grip.
- Temperature – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate decreases the load capacity.
Safe handling of neodymium magnets
Health Danger
People with a pacemaker must keep an safe separation from magnets. The magnetic field can stop the operation of the implant.
Fragile material
Neodymium magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets will cause them cracking into shards.
Dust explosion hazard
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Immense force
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Warning for allergy sufferers
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness occurs, cease working with magnets and wear gloves.
Thermal limits
Standard neodymium magnets (grade N) lose power when the temperature exceeds 80°C. This process is irreversible.
GPS and phone interference
Note: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.
Choking Hazard
Only for adults. Tiny parts can be swallowed, causing severe trauma. Keep away from kids and pets.
Bone fractures
Large magnets can smash fingers instantly. Under no circumstances place your hand betwixt two attracting surfaces.
Safe distance
Powerful magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
