Strengths and weaknesses of neodymium magnets.
Advantages
- Their power remains stable, and after around 10 years it drops only by ~1% (according to research),
- They have excellent resistance to magnetic field loss due to external fields,
- By covering with a lustrous layer of nickel, the element has an modern look,
- The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to modularity in shaping and the capacity to modify to specific needs,
- Huge importance in advanced technology sectors – they serve a role in hard drives, brushless drives, precision medical tools, also industrial machines.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- We suggest cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical after entering the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Holding force characteristics
Maximum lifting capacity of the magnet – what affects it?
- with the use of a sheet made of special test steel, ensuring full magnetic saturation
- possessing a thickness of min. 10 mm to avoid saturation
- characterized by smoothness
- with direct contact (without impurities)
- during detachment in a direction perpendicular to the mounting surface
- in stable room temperature
Determinants of lifting force in real conditions
- Gap (between the magnet and the metal), since even a tiny distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys attracts identically. High carbon content worsen the interaction with the magnet.
- Surface structure – the more even the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate decreases the load capacity.
Safe handling of NdFeB magnets
Dust is flammable
Fire warning: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
Data carriers
Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (heart implants, medical aids, timepieces).
ICD Warning
Individuals with a ICD must maintain an large gap from magnets. The magnetic field can stop the operation of the life-saving device.
Shattering risk
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets will cause them breaking into small pieces.
Heat warning
Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Bodily injuries
Mind your fingers. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!
Respect the power
Use magnets consciously. Their immense force can shock even experienced users. Be vigilant and respect their force.
Adults only
Strictly keep magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are fatal.
Skin irritation risks
A percentage of the population suffer from a contact allergy to nickel, which is the common plating for NdFeB magnets. Prolonged contact might lead to skin redness. It is best to wear protective gloves.
Compass and GPS
Be aware: neodymium magnets generate a field that disrupts sensitive sensors. Keep a separation from your mobile, device, and GPS.
