Strengths as well as weaknesses of rare earth magnets.
Strengths
- They have unchanged lifting capacity, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
- They are noted for resistance to demagnetization induced by external magnetic fields,
- By applying a decorative coating of silver, the element presents an elegant look,
- Magnets are characterized by extremely high magnetic induction on the surface,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- In view of the option of flexible forming and customization to individualized solutions, magnetic components can be created in a broad palette of shapes and sizes, which makes them more universal,
- Versatile presence in future technologies – they find application in magnetic memories, drive modules, medical devices, also technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Disadvantages
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing threads and complicated forms in magnets, we propose using a housing - magnetic mechanism.
- Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these products can disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Magnetic strength at its maximum – what affects it?
- with the use of a sheet made of special test steel, ensuring full magnetic saturation
- with a thickness no less than 10 mm
- characterized by even structure
- under conditions of gap-free contact (surface-to-surface)
- under axial force vector (90-degree angle)
- in stable room temperature
Magnet lifting force in use – key factors
- Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel grade – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
- Surface finish – ideal contact is obtained only on polished steel. Rough texture reduce the real contact area, reducing force.
- Thermal factor – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate lowers the holding force.
Precautions when working with NdFeB magnets
Life threat
Warning for patients: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Magnetic interference
Be aware: rare earth magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your mobile, device, and GPS.
Material brittleness
Neodymium magnets are sintered ceramics, which means they are very brittle. Collision of two magnets leads to them cracking into small pieces.
Nickel coating and allergies
It is widely known that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, refrain from touching magnets with bare hands or opt for encased magnets.
Dust is flammable
Powder generated during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Demagnetization risk
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.
Crushing risk
Risk of injury: The pulling power is so immense that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Keep away from children
Adult use only. Tiny parts pose a choking risk, leading to serious injuries. Store away from kids and pets.
Electronic devices
Data protection: Strong magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).
Do not underestimate power
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
