Strengths and weaknesses of rare earth magnets.
Advantages
- Their strength is durable, and after around 10 years it drops only by ~1% (theoretically),
- Neodymium magnets remain remarkably resistant to loss of magnetic properties caused by external interference,
- A magnet with a shiny gold surface is more attractive,
- Magnets are characterized by excellent magnetic induction on the outer side,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of individual modeling as well as adapting to atypical needs,
- Huge importance in modern technologies – they are commonly used in HDD drives, electric drive systems, medical equipment, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in compact constructions
Limitations
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as 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 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 cover - magnetic mount.
- Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Furthermore, small elements of these magnets are able to complicate diagnosis medical after entering the body.
- Due to complex production process, their price exceeds standard values,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- using a base made of mild steel, functioning as a circuit closing element
- with a cross-section minimum 10 mm
- characterized by smoothness
- with total lack of distance (without paint)
- during pulling in a direction perpendicular to the mounting surface
- at conditions approx. 20°C
Key elements affecting lifting force
- Air gap (betwixt the magnet and the metal), as even a tiny distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to paint, rust or debris).
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of nominal force).
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
- Plate texture – ground elements ensure maximum contact, which increases force. Uneven metal weaken the grip.
- Thermal factor – hot environment weakens pulling force. Too high temperature can permanently damage the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Warnings
Shattering risk
NdFeB magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets leads to them shattering into shards.
Sensitization to coating
Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness happens, immediately stop handling magnets and wear gloves.
Swallowing risk
These products are not intended for children. Accidental ingestion of multiple magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and necessitates immediate surgery.
Medical implants
Patients with a ICD must keep an absolute distance from magnets. The magnetic field can disrupt the operation of the implant.
Cards and drives
Do not bring magnets close to a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Flammability
Mechanical processing of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Do not overheat magnets
Regular neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.
Precision electronics
GPS units and mobile phones are highly sensitive to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Crushing force
Danger of trauma: The pulling power is so great that it can result in blood blisters, pinching, and broken bones. Use thick gloves.
Handling guide
Use magnets with awareness. Their powerful strength can surprise even experienced users. Stay alert and do not underestimate their force.
