Strengths as well as weaknesses of rare earth magnets.
Benefits
- They retain attractive force for nearly 10 years – the drop is just ~1% (according to analyses),
- They do not lose their magnetic properties even under strong external field,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- Neodymium magnets ensure maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
- Due to the potential of flexible molding and adaptation to specialized projects, neodymium magnets can be modeled in a variety of shapes and sizes, which increases their versatility,
- Huge importance in advanced technology sectors – they are used in data components, brushless drives, medical equipment, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in small systems
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We suggest a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex shapes.
- Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small components of these products are able to complicate diagnosis medical when they are in the body.
- Due to neodymium price, their price is relatively high,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what it depends on?
- using a sheet made of mild steel, functioning as a magnetic yoke
- with a cross-section of at least 10 mm
- with an ground contact surface
- under conditions of gap-free contact (surface-to-surface)
- for force acting at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Distance – existence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Plate material – low-carbon steel attracts best. Alloy admixtures lower magnetic permeability and holding force.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Thermal factor – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate reduces the lifting capacity.
Safe handling of NdFeB magnets
Flammability
Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Operating temperature
Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.
Keep away from children
NdFeB magnets are not toys. Accidental ingestion of multiple magnets can lead to them attracting across intestines, which constitutes a severe health hazard and necessitates urgent medical intervention.
Data carriers
Data protection: Strong magnets can damage data carriers and sensitive devices (heart implants, medical aids, timepieces).
Hand protection
Big blocks can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.
Impact on smartphones
Navigation devices and smartphones are highly susceptible to magnetic fields. Direct contact with a strong magnet can permanently damage the sensors in your phone.
Danger to pacemakers
Medical warning: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Metal Allergy
Medical facts indicate that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid direct skin contact or choose encased magnets.
Shattering risk
NdFeB magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets leads to them cracking into shards.
Respect the power
Use magnets consciously. Their huge power can surprise even professionals. Be vigilant and respect their power.
