Pros and cons of rare earth magnets.
Benefits
- They do not lose magnetism, even after around ten years – the decrease in lifting capacity is only ~1% (theoretically),
- Neodymium magnets are characterized by highly resistant to loss of magnetic properties caused by external interference,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in designing and the ability to customize to client solutions,
- Significant place in modern technologies – they serve a role in computer drives, electric drive systems, diagnostic systems, and industrial machines.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Cons
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their strength 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 water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of producing threads in the magnet and complex shapes - preferred is a housing - mounting mechanism.
- Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. Additionally, small components of these products can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what it depends on?
- using a base made of mild steel, serving as a ideal flux conductor
- whose thickness reaches at least 10 mm
- characterized by lack of roughness
- under conditions of gap-free contact (metal-to-metal)
- for force applied at a right angle (in the magnet axis)
- in stable room temperature
Practical lifting capacity: influencing factors
- Distance – the presence of foreign body (paint, dirt, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel attracts best. Alloy steels lower magnetic properties and holding force.
- Surface finish – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
Impact on smartphones
An intense magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Keep magnets near a smartphone to prevent breaking the sensors.
Swallowing risk
Always store magnets away from children. Ingestion danger is high, and the consequences of magnets clamping inside the body are tragic.
Maximum temperature
Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. This process is irreversible.
Pinching danger
Danger of trauma: The pulling power is so immense that it can cause hematomas, pinching, and even bone fractures. Use thick gloves.
Warning for allergy sufferers
Medical facts indicate that nickel (standard magnet coating) is a strong allergen. If you have an allergy, refrain from touching magnets with bare hands or choose versions in plastic housing.
Safe distance
Avoid bringing magnets near a wallet, laptop, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
Machining danger
Powder created during cutting of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Danger to pacemakers
For implant holders: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or request help to handle the magnets.
Magnet fragility
Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Do not underestimate power
Handle with care. Rare earth magnets act from a distance and connect with massive power, often faster than you can move away.
