Strengths and weaknesses of Nd2Fe14B magnets.
Benefits
- They have unchanged lifting capacity, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
- They do not lose their magnetic properties even under close interference source,
- By using a lustrous coating of nickel, the element gains an proper look,
- Neodymium magnets generate maximum magnetic induction on a contact point, which increases force concentration,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Thanks to flexibility in forming and the capacity to adapt to client solutions,
- Wide application in modern technologies – they are commonly used in computer drives, brushless drives, medical devices, and modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- 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
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Health risk resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child safety. It is also worth noting that small components of these magnets can be problematic in diagnostics medical when they are in the body.
- Due to expensive raw materials, their price is relatively high,
Holding force characteristics
Maximum magnetic pulling force – what it depends on?
- with the contact of a yoke made of special test steel, ensuring maximum field concentration
- whose transverse dimension is min. 10 mm
- with an ideally smooth touching surface
- under conditions of ideal adhesion (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- in stable room temperature
Impact of factors on magnetic holding capacity in practice
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Plate thickness – insufficiently thick steel does not accept the full field, causing part of the power to be escaped to the other side.
- Steel grade – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Uneven metal weaken the grip.
- Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was measured with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the load capacity.
Safety rules for work with neodymium magnets
Fire warning
Fire warning: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.
Do not underestimate power
Before use, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Pinching danger
Big blocks can smash fingers instantly. Under no circumstances place your hand between two attracting surfaces.
Nickel allergy
Medical facts indicate that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, refrain from touching magnets with bare hands or select versions in plastic housing.
Electronic hazard
Do not bring magnets close to a purse, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.
Compass and GPS
An intense magnetic field interferes with the operation of magnetometers in smartphones and GPS navigation. Maintain magnets close to a device to prevent breaking the sensors.
Keep away from children
Strictly store magnets away from children. Choking hazard is high, and the effects of magnets clamping inside the body are fatal.
Material brittleness
Despite the nickel coating, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Life threat
Patients with a ICD should keep an safe separation from magnets. The magnetism can disrupt the functioning of the life-saving device.
Operating temperature
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. The loss of strength is permanent.
