Strengths and weaknesses of rare earth magnets.
Strengths
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
- Neodymium magnets are distinguished by remarkably resistant to demagnetization caused by magnetic disturbances,
- By covering with a shiny coating of gold, the element has an professional look,
- Magnetic induction on the top side of the magnet is strong,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Possibility of individual machining and optimizing to atypical applications,
- Fundamental importance in advanced technology sectors – they are used in HDD drives, motor assemblies, advanced medical instruments, also modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Cons
- At very strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- We recommend a housing - magnetic holder, due to difficulties in realizing threads inside the magnet and complex forms.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these products can complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what it depends on?
- with the contact of a yoke made of special test steel, ensuring maximum field concentration
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with an polished touching surface
- under conditions of ideal adhesion (surface-to-surface)
- under axial force direction (90-degree angle)
- in neutral thermal conditions
Lifting capacity in practice – influencing factors
- Space between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Steel thickness – insufficiently thick plate does not close the flux, causing part of the flux to be lost to the other side.
- Steel grade – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with neodymium magnets
Magnets are brittle
Neodymium magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets leads to them cracking into small pieces.
Power loss in heat
Watch the temperature. Heating the magnet to high heat will ruin its properties and pulling force.
Bodily injuries
Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
GPS Danger
GPS units and mobile phones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Medical implants
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Product not for children
NdFeB magnets are not intended for children. Swallowing multiple magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and necessitates immediate surgery.
Keep away from computers
Very strong magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.
Dust is flammable
Powder generated during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.
Skin irritation risks
Some people have a sensitization to Ni, which is the common plating for neodymium magnets. Extended handling can result in a rash. It is best to wear safety gloves.
Safe operation
Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.
