Strengths as well as weaknesses of rare earth magnets.
Strengths
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (according to literature),
- Magnets perfectly protect themselves against demagnetization caused by foreign field sources,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Magnetic induction on the working layer of the magnet turns out to be very high,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- In view of the option of accurate molding and adaptation to unique requirements, NdFeB magnets can be modeled in a variety of forms and dimensions, which expands the range of possible applications,
- Wide application in innovative solutions – they find application in magnetic memories, motor assemblies, medical equipment, as well as other advanced devices.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Weaknesses
- To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely 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 those in rubber or plastics, which prevent oxidation as well as corrosion.
- We suggest casing - magnetic mount, due to difficulties in producing threads inside the magnet and complicated forms.
- Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these devices can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what affects it?
- using a base made of high-permeability steel, functioning as a magnetic yoke
- with a cross-section of at least 10 mm
- with an ideally smooth touching surface
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction perpendicular to the plane
- at temperature room level
Determinants of lifting force in real conditions
- Clearance – the presence of foreign body (paint, tape, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Direction of force – highest force is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Material composition – different alloys attracts identically. High carbon content worsen the attraction effect.
- Surface structure – the more even the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was assessed with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate decreases the holding force.
Safe handling of NdFeB magnets
Swallowing risk
Always store magnets away from children. Ingestion danger is high, and the consequences of magnets clamping inside the body are tragic.
Physical harm
Mind your fingers. Two large magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Health Danger
For implant holders: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or request help to work with the magnets.
Eye protection
NdFeB magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets will cause them breaking into shards.
Safe operation
Handle with care. Rare earth magnets attract from a distance and snap with huge force, often faster than you can react.
Electronic hazard
Data protection: Strong magnets can ruin payment cards and delicate electronics (heart implants, medical aids, mechanical watches).
GPS and phone interference
A strong magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Do not bring magnets close to a device to avoid damaging the sensors.
Thermal limits
Standard neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
Mechanical processing
Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.
Nickel coating and allergies
It is widely known that nickel (the usual finish) is a potent allergen. For allergy sufferers, avoid direct skin contact and opt for coated magnets.
