Advantages and disadvantages of rare earth magnets.
Strengths
- They have unchanged lifting capacity, and over more than ten years their performance decreases symbolically – ~1% (in testing),
- They possess excellent resistance to magnetic field loss when exposed to external fields,
- By covering with a lustrous coating of nickel, the element gains an elegant look,
- Neodymium magnets achieve maximum magnetic induction on a small area, which increases force concentration,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to flexibility in shaping and the ability to customize to specific needs,
- Key role in innovative solutions – they are utilized in HDD drives, electromotive mechanisms, advanced medical instruments, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in miniature devices
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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 extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Due to limitations in realizing threads and complex shapes in magnets, we recommend using a housing - magnetic holder.
- Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Additionally, small elements of these magnets can complicate diagnosis medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Detachment force of the magnet in optimal conditions – what affects it?
- using a sheet made of high-permeability steel, serving as a ideal flux conductor
- with a thickness no less than 10 mm
- with an polished contact surface
- with total lack of distance (no paint)
- for force applied at a right angle (in the magnet axis)
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Gap (betwixt the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds much less (typically approx. 20-30% of maximum force).
- Steel thickness – too thin sheet does not close the flux, causing part of the flux to be lost to the other side.
- Material type – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
- Surface condition – smooth surfaces ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
- Temperature influence – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was assessed by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Medical implants
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Dust is flammable
Combustion risk: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.
Handling guide
Handle magnets with awareness. Their huge power can shock even experienced users. Plan your moves and do not underestimate their force.
This is not a toy
Always keep magnets away from children. Ingestion danger is high, and the effects of magnets connecting inside the body are very dangerous.
GPS Danger
GPS units and smartphones are highly sensitive to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Shattering risk
NdFeB magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets will cause them breaking into shards.
Serious injuries
Mind your fingers. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!
Magnetic media
Data protection: Strong magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, timepieces).
Permanent damage
Regular neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Sensitization to coating
Medical facts indicate that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, refrain from direct skin contact and choose versions in plastic housing.
