Pros as well as cons of rare earth magnets.
Advantages
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (according to literature),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- Thanks to the shimmering finish, the coating of Ni-Cu-Ni, gold, or silver gives an elegant appearance,
- Magnets are distinguished by huge magnetic induction on the active area,
- 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...
- Possibility of individual machining and adjusting to specific requirements,
- Universal use in electronics industry – they are utilized in HDD drives, motor assemblies, medical equipment, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in small systems
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- We recommend a housing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, tiny parts of these devices 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
Lifting parameters
Maximum holding power of the magnet – what affects it?
- on a base made of mild steel, effectively closing the magnetic field
- whose transverse dimension is min. 10 mm
- characterized by smoothness
- under conditions of no distance (surface-to-surface)
- during detachment in a direction perpendicular to the mounting surface
- at temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Clearance – the presence of foreign body (rust, dirt, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Plate material – low-carbon steel gives the best results. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Smoothness – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Temperature influence – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet’s surface and the plate decreases the holding force.
Safety rules for work with NdFeB magnets
Danger to the youngest
These products are not toys. Swallowing several magnets may result in them attracting across intestines, which constitutes a critical condition and requires urgent medical intervention.
Serious injuries
Large magnets can smash fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.
Heat sensitivity
Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
Electronic hazard
Data protection: Neodymium magnets can damage data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
Protective goggles
Despite metallic appearance, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Dust explosion hazard
Powder generated during cutting of magnets is self-igniting. Do not drill into magnets unless you are an expert.
ICD Warning
Medical warning: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Powerful field
Handle magnets consciously. Their powerful strength can surprise even professionals. Stay alert and do not underestimate their force.
Magnetic interference
GPS units and smartphones are highly sensitive to magnetism. Direct contact with a strong magnet can ruin the sensors in your phone.
Warning for allergy sufferers
A percentage of the population have a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Prolonged contact can result in skin redness. It is best to use protective gloves.
