Strengths and weaknesses of rare earth magnets.
Advantages
- They do not lose strength, even after nearly 10 years – the decrease in power is only ~1% (based on measurements),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- By applying a decorative coating of silver, the element presents an aesthetic look,
- Magnets have impressive magnetic induction on the outer layer,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to freedom in designing and the capacity to customize to complex applications,
- Versatile presence in future technologies – they find application in HDD drives, electromotive mechanisms, advanced medical instruments, also industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- 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
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing nuts and complex forms in magnets, we recommend using a housing - magnetic mount.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- Due to expensive raw materials, their price is higher than average,
Pull force analysis
Highest magnetic holding force – what it depends on?
- using a plate made of mild steel, acting as a ideal flux conductor
- with a thickness no less than 10 mm
- characterized by smoothness
- without the slightest clearance between the magnet and steel
- during detachment in a direction vertical to the plane
- at room temperature
Practical lifting capacity: influencing factors
- Distance (between the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, rust or dirt).
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Steel thickness – too thin sheet does not accept the full field, causing part of the power to be lost to the other side.
- Metal type – different alloys reacts the same. Alloy additives worsen the attraction effect.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Heat – neodymium magnets 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 was determined with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Safety rules for work with NdFeB magnets
Allergic reactions
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness appears, immediately stop working with magnets and use protective gear.
Do not give to children
Adult use only. Tiny parts pose a choking risk, leading to intestinal necrosis. Store out of reach of kids and pets.
Do not overheat magnets
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Precision electronics
An intense magnetic field negatively affects the operation of compasses in smartphones and GPS navigation. Maintain magnets near a device to prevent breaking the sensors.
Fire warning
Mechanical processing of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Magnets are brittle
Watch out for shards. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Bodily injuries
Watch your fingers. Two powerful magnets will snap together instantly with a force of massive weight, destroying everything in their path. Be careful!
Respect the power
Be careful. Neodymium magnets act from a long distance and connect with huge force, often faster than you can react.
Medical implants
Patients with a pacemaker should keep an large gap from magnets. The magnetic field can stop the functioning of the life-saving device.
Data carriers
Powerful magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.
