Pros and cons of rare earth magnets.
Advantages
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
- They have excellent resistance to magnetism drop due to opposing magnetic fields,
- By applying a lustrous layer of nickel, the element has an professional look,
- Magnets possess extremely high magnetic induction on the surface,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Considering the potential of free shaping and customization to specialized needs, magnetic components can be modeled in a variety of forms and dimensions, which expands the range of possible applications,
- Fundamental importance in advanced technology sectors – they are utilized in mass storage devices, drive modules, diagnostic systems, also complex engineering applications.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting 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 suffer a drop in force. Often, when the temperature exceeds 80°C, their power 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Due to limitations in realizing nuts and complicated shapes in magnets, we propose using casing - magnetic holder.
- Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these magnets can complicate diagnosis medical in case of swallowing.
- Due to neodymium price, their price exceeds standard values,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what affects it?
- using a base made of mild steel, serving as a circuit closing element
- with a cross-section minimum 10 mm
- with a plane free of scratches
- with direct contact (without paint)
- under axial application of breakaway force (90-degree angle)
- at room temperature
Determinants of practical lifting force of a magnet
- Gap (between the magnet and the plate), since even a very small distance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to paint, corrosion or debris).
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Metal type – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
- Base smoothness – the more even the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was assessed using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
H&S for magnets
Immense force
Handle with care. Neodymium magnets act from a long distance and connect with massive power, often faster than you can move away.
Impact on smartphones
GPS units and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.
Pinching danger
Big blocks can smash fingers in a fraction of a second. Do not put your hand betwixt two strong magnets.
Allergy Warning
Studies show that the nickel plating (the usual finish) is a strong allergen. For allergy sufferers, avoid direct skin contact and opt for versions in plastic housing.
Permanent damage
Watch the temperature. Exposing the magnet to high heat will ruin its properties and pulling force.
Choking Hazard
Neodymium magnets are not intended for children. Accidental ingestion of multiple magnets can lead to them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.
Danger to pacemakers
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Cards and drives
Equipment safety: Strong magnets can ruin payment cards and sensitive devices (heart implants, medical aids, timepieces).
Eye protection
NdFeB magnets are ceramic materials, which means they are very brittle. Collision of two magnets leads to them cracking into small pieces.
Dust is flammable
Mechanical processing of neodymium magnets carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
