Pros as well as cons of rare earth magnets.
Strengths
- Their magnetic field is durable, and after approximately 10 years it decreases only by ~1% (according to research),
- They possess excellent resistance to magnetism drop when exposed to external magnetic sources,
- In other words, due to the metallic finish of gold, the element gains visual value,
- The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- In view of the possibility of accurate molding and customization to custom projects, magnetic components can be produced in a broad palette of geometric configurations, which amplifies use scope,
- Universal use in electronics industry – they serve a role in HDD drives, electromotive mechanisms, advanced medical instruments, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in compact constructions
Limitations
- At strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets lose power 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 extremely resistant to heat
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- We suggest casing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these devices can complicate diagnosis medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what it depends on?
- on a base made of mild steel, perfectly concentrating the magnetic flux
- whose transverse dimension is min. 10 mm
- with an ideally smooth touching surface
- with zero gap (no coatings)
- under perpendicular force direction (90-degree angle)
- in stable room temperature
Lifting capacity in practice – influencing factors
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds much less (often approx. 20-30% of maximum force).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel type – mild steel gives the best results. Higher carbon content reduce magnetic properties and holding force.
- Smoothness – full contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).
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 lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate lowers the load capacity.
Warnings
Power loss in heat
Do not overheat. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Electronic hazard
Avoid bringing magnets close to a purse, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.
GPS Danger
Be aware: neodymium magnets produce a field that interferes with precision electronics. Maintain a separation from your mobile, device, and GPS.
Pinching danger
Large magnets can smash fingers in a fraction of a second. Never put your hand between two attracting surfaces.
Material brittleness
Beware of splinters. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
Nickel coating and allergies
It is widely known that the nickel plating (the usual finish) is a strong allergen. For allergy sufferers, avoid touching magnets with bare hands or choose versions in plastic housing.
Mechanical processing
Drilling and cutting of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
ICD Warning
Medical warning: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Powerful field
Handle magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and respect their force.
Adults only
Only for adults. Tiny parts pose a choking risk, leading to severe trauma. Keep away from kids and pets.
