Advantages and disadvantages of neodymium magnets.
Pros
- They have stable power, and over around ten years their attraction force decreases symbolically – ~1% (in testing),
- Magnets perfectly defend themselves against loss of magnetization caused by ambient magnetic noise,
- By using a lustrous coating of silver, the element has an modern look,
- Neodymium magnets ensure maximum magnetic induction on a small area, which increases force concentration,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to the option of accurate forming and adaptation to specialized needs, neodymium magnets can be manufactured in a broad palette of forms and dimensions, which makes them more universal,
- Versatile presence in future technologies – they are used in computer drives, motor assemblies, advanced medical instruments, also industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- 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 protects them against impacts but also increases their durability
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We suggest casing - magnetic mount, due to difficulties in creating nuts inside the magnet and complex forms.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Highest magnetic holding force – what contributes to it?
- on a block made of structural steel, perfectly concentrating the magnetic field
- whose thickness reaches at least 10 mm
- characterized by lack of roughness
- without any clearance between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at conditions approx. 20°C
Determinants of practical lifting force of a magnet
- Distance (betwixt the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, rust or debris).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Material composition – not every steel reacts the same. Alloy additives worsen the attraction effect.
- Surface finish – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet and the plate decreases the lifting capacity.
Warnings
Keep away from children
Only for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Store away from kids and pets.
Dust is flammable
Mechanical processing of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Threat to navigation
Note: rare earth magnets produce a field that confuses precision electronics. Maintain a separation from your mobile, device, and GPS.
Data carriers
Device Safety: Strong magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, timepieces).
Conscious usage
Exercise caution. Rare earth magnets act from a distance and connect with huge force, often faster than you can react.
Hand protection
Risk of injury: The pulling power is so immense that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Material brittleness
Beware of splinters. Magnets can explode upon violent connection, ejecting shards into the air. Eye protection is mandatory.
Implant safety
People with a ICD have to keep an absolute distance from magnets. The magnetism can stop the operation of the life-saving device.
Avoid contact if allergic
Certain individuals experience a contact allergy to Ni, which is the standard coating for neodymium magnets. Prolonged contact might lead to skin redness. It is best to use safety gloves.
Demagnetization risk
Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.
