Pros as well as cons of Nd2Fe14B magnets.
Pros
- Their magnetic field is maintained, and after approximately ten years it decreases only by ~1% (according to research),
- They possess excellent resistance to magnetic field loss due to external magnetic sources,
- Thanks to the metallic finish, the plating of Ni-Cu-Ni, gold, or silver-plated gives an visually attractive appearance,
- Neodymium magnets ensure maximum magnetic induction on a their surface, which allows for strong attraction,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
- Considering the possibility of accurate shaping and customization to specialized needs, NdFeB magnets can be created in a variety of forms and dimensions, which increases their versatility,
- Significant place in advanced technology sectors – they are used in magnetic memories, electromotive mechanisms, advanced medical instruments, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in miniature devices
Limitations
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- 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 advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Due to limitations in producing threads and complex shapes in magnets, we propose using casing - magnetic holder.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small elements of these magnets can disrupt the diagnostic process medical after entering the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- using a plate made of high-permeability steel, functioning as a circuit closing element
- with a cross-section minimum 10 mm
- with an polished contact surface
- under conditions of gap-free contact (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- at room temperature
Determinants of practical lifting force of a magnet
- Gap between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Metal type – not every steel reacts the same. Alloy additives weaken the attraction effect.
- Plate texture – smooth surfaces ensure maximum contact, which increases force. Uneven metal weaken the grip.
- Thermal environment – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
Safe handling of neodymium magnets
Phone sensors
A powerful magnetic field disrupts the functioning of compasses in phones and navigation systems. Maintain magnets near a device to prevent breaking the sensors.
Electronic hazard
Do not bring magnets close to a wallet, laptop, or TV. The magnetic field can permanently damage these devices and erase data from cards.
Demagnetization risk
Regular neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. This process is irreversible.
Hand protection
Big blocks can crush fingers in a fraction of a second. Never place your hand betwixt two strong magnets.
Fire risk
Dust produced during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Allergy Warning
A percentage of the population have a contact allergy to nickel, which is the standard coating for NdFeB magnets. Extended handling might lead to an allergic reaction. It is best to wear safety gloves.
Choking Hazard
NdFeB magnets are not toys. Accidental ingestion of several magnets may result in them attracting across intestines, which constitutes a direct threat to life and necessitates immediate surgery.
Protective goggles
Neodymium magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets leads to them shattering into small pieces.
Handling guide
Be careful. Rare earth magnets act from a distance and snap with massive power, often quicker than you can react.
Medical implants
Individuals with a pacemaker should keep an safe separation from magnets. The magnetic field can stop the operation of the life-saving device.
