Strengths and weaknesses of Nd2Fe14B magnets.
Advantages
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
- They do not lose their magnetic properties even under external field action,
- Thanks to the metallic finish, the coating of Ni-Cu-Ni, gold, or silver-plated gives an visually attractive appearance,
- Magnets exhibit impressive magnetic induction on the surface,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of individual modeling as well as modifying to precise requirements,
- Key role in future technologies – they serve a role in mass storage devices, drive modules, advanced medical instruments, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in small systems
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in strength. 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
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in creating nuts and complicated forms in magnets, we propose using casing - magnetic mechanism.
- Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, small components of these devices can be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets is economically unviable,
Holding force characteristics
Maximum holding power of the magnet – what contributes to it?
- using a plate made of high-permeability steel, acting as a magnetic yoke
- with a cross-section of at least 10 mm
- with an polished contact surface
- without any clearance between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Practical lifting capacity: influencing factors
- Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds much less (typically approx. 20-30% of maximum force).
- Base massiveness – insufficiently thick plate does not accept the full field, causing part of the power to be lost into the air.
- Chemical composition of the base – low-carbon steel gives the best results. Higher carbon content decrease magnetic permeability and holding force.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was determined by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with NdFeB magnets
Protect data
Device Safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, medical aids, timepieces).
Warning for allergy sufferers
It is widely known that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid touching magnets with bare hands or choose encased magnets.
Safe operation
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
ICD Warning
For implant holders: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or request help to handle the magnets.
Crushing force
Protect your hands. Two large magnets will snap together instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!
Machining danger
Powder created during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Permanent damage
Regular neodymium magnets (N-type) lose power when the temperature exceeds 80°C. The loss of strength is permanent.
Compass and GPS
Note: neodymium magnets produce a field that interferes with sensitive sensors. Keep a separation from your mobile, tablet, and navigation systems.
Swallowing risk
Neodymium magnets are not suitable for play. Swallowing several magnets may result in them attracting across intestines, which constitutes a severe health hazard and necessitates immediate surgery.
Material brittleness
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets leads to them breaking into small pieces.
