Advantages and disadvantages of rare earth magnets.
Strengths
- They do not lose strength, even over around 10 years – the reduction in power is only ~1% (based on measurements),
- They have excellent resistance to magnetism drop as a result of external fields,
- In other words, due to the glossy layer of nickel, the element gains a professional look,
- Neodymium magnets achieve maximum magnetic induction on a their surface, which ensures high operational effectiveness,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Thanks to versatility in constructing and the ability to adapt to individual projects,
- Huge importance in advanced technology sectors – they find application in HDD drives, drive modules, precision medical tools, as well as industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Limited ability of creating threads in the magnet and complex forms - preferred is casing - mounting mechanism.
- Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small components of these products can be problematic in diagnostics medical in case of swallowing.
- With large orders the cost of neodymium magnets can be a barrier,
Pull force analysis
Detachment force of the magnet in optimal conditions – what contributes to it?
- with the contact of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- whose thickness reaches at least 10 mm
- characterized by lack of roughness
- with direct contact (without paint)
- during detachment in a direction vertical to the plane
- in neutral thermal conditions
Determinants of lifting force in real conditions
- Distance (betwixt the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel gives the best results. Alloy steels reduce magnetic properties and holding force.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Thermal environment – heating the magnet causes a temporary drop of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the lifting capacity.
Precautions when working with neodymium magnets
Maximum temperature
Regular neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.
Warning for heart patients
For implant holders: Powerful magnets affect electronics. Keep at least 30 cm distance or request help to handle the magnets.
Pinching danger
Big blocks can break fingers in a fraction of a second. Do not place your hand betwixt two strong magnets.
Dust is flammable
Fire warning: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.
Protect data
Powerful magnetic fields can destroy records on payment cards, HDDs, and storage devices. Stay away of min. 10 cm.
Precision electronics
A powerful magnetic field interferes with the functioning of compasses in phones and navigation systems. Maintain magnets close to a device to avoid breaking the sensors.
Protective goggles
Beware of splinters. Magnets can fracture upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Skin irritation risks
It is widely known that nickel (the usual finish) is a common allergen. If your skin reacts to metals, prevent direct skin contact and opt for coated magnets.
Handling rules
Use magnets consciously. Their powerful strength can shock even experienced users. Be vigilant and respect their power.
Choking Hazard
Product intended for adults. Small elements can be swallowed, leading to serious injuries. Store out of reach of children and animals.
