Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- They retain attractive force for almost ten years – the loss is just ~1% (based on simulations),
- They retain their magnetic properties even under external field action,
- A magnet with a metallic nickel surface looks better,
- Magnetic induction on the working layer of the magnet remains exceptional,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to modularity in designing and the capacity to adapt to individual projects,
- Universal use in future technologies – they find application in mass storage devices, motor assemblies, diagnostic systems, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in small systems
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures 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 immune to moisture, when using outdoors
- Limited possibility of creating nuts in the magnet and complicated shapes - preferred is cover - mounting mechanism.
- Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small components of these magnets can disrupt the diagnostic process medical in case of swallowing.
- Due to neodymium price, their price exceeds standard values,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- on a base made of structural steel, perfectly concentrating the magnetic flux
- whose transverse dimension is min. 10 mm
- characterized by even structure
- under conditions of gap-free contact (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature room level
What influences lifting capacity in practice
- Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Load vector – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, 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. Hardened steels may have worse magnetic properties.
- Surface finish – full contact is obtained only on polished steel. Rough texture reduce the real contact area, reducing force.
- Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Handling guide
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Impact on smartphones
Remember: neodymium magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.
Metal Allergy
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, cease handling magnets and use protective gear.
Maximum temperature
Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. Damage is permanent.
Dust is flammable
Combustion risk: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
Hand protection
Watch your fingers. Two large magnets will join immediately with a force of massive weight, destroying everything in their path. Be careful!
Swallowing risk
NdFeB magnets are not toys. Swallowing a few magnets may result in them connecting inside the digestive tract, which constitutes a severe health hazard and requires immediate surgery.
Eye protection
Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
ICD Warning
Life threat: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Data carriers
Do not bring magnets close to a purse, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.
