Advantages and disadvantages of neodymium magnets.
Advantages
- Their strength is durable, and after around 10 years it drops only by ~1% (theoretically),
- Neodymium magnets are exceptionally resistant to demagnetization caused by external field sources,
- The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the working layer of the magnet remains extremely intense,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
- Possibility of detailed creating as well as modifying to specific needs,
- Fundamental importance in innovative solutions – they find application in hard drives, electric motors, medical devices, also modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- They are fragile 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 suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as 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 threads and complicated forms in magnets, we recommend using casing - magnetic mechanism.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small components of these magnets can disrupt the diagnostic process medical after entering the body.
- With mass production the cost of neodymium magnets is economically unviable,
Lifting parameters
Best holding force of the magnet in ideal parameters – what it depends on?
- using a base made of low-carbon steel, functioning as a circuit closing element
- with a thickness minimum 10 mm
- characterized by smoothness
- without any air gap between the magnet and steel
- during detachment in a direction perpendicular to the mounting surface
- in stable room temperature
Practical lifting capacity: influencing factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds much less (often approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Hardened steels may have worse magnetic properties.
- Surface structure – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, whereas under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate decreases the load capacity.
Safety rules for work with NdFeB magnets
This is not a toy
Product intended for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Store out of reach of children and animals.
Bone fractures
Protect your hands. Two large magnets will join instantly with a force of massive weight, destroying everything in their path. Be careful!
Compass and GPS
Note: neodymium magnets produce a field that disrupts sensitive sensors. Keep a separation from your mobile, device, and navigation systems.
Warning for heart patients
Medical warning: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Material brittleness
NdFeB magnets are ceramic materials, meaning they are very brittle. Collision of two magnets leads to them shattering into small pieces.
Mechanical processing
Drilling and cutting of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Warning for allergy sufferers
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, immediately stop handling magnets and wear gloves.
Thermal limits
Watch the temperature. Exposing the magnet to high heat will ruin its properties and pulling force.
Threat to electronics
Equipment safety: Strong magnets can damage data carriers and sensitive devices (pacemakers, medical aids, timepieces).
Handling guide
Handle with care. Neodymium magnets attract from a distance and connect with huge force, often faster than you can move away.
