Pros as well as cons of Nd2Fe14B magnets.
Pros
- They have stable power, and over more than 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They do not lose their magnetic properties even under external field action,
- The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to look better,
- Magnets have extremely high magnetic induction on the outer side,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to modularity in designing and the capacity to customize to client solutions,
- Key role in future technologies – they are commonly used in magnetic memories, electromotive mechanisms, precision medical tools, also modern systems.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- We suggest cover - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated forms.
- Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these magnets can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- on a block made of structural steel, effectively closing the magnetic flux
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with an ground touching surface
- with direct contact (no coatings)
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature room level
Magnet lifting force in use – key factors
- Air gap (betwixt the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Material composition – not every steel reacts the same. High carbon content weaken the interaction with the magnet.
- Smoothness – ideal contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Safe handling of neodymium magnets
Phone sensors
An intense magnetic field disrupts the operation of magnetometers in phones and GPS navigation. Maintain magnets near a smartphone to prevent damaging the sensors.
Avoid contact if allergic
A percentage of the population have a hypersensitivity to nickel, which is the standard coating for neodymium magnets. Extended handling may cause skin redness. We recommend use safety gloves.
Protective goggles
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Heat warning
Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
Powerful field
Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Finger safety
Large magnets can smash fingers instantly. Do not put your hand betwixt two attracting surfaces.
ICD Warning
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
Product not for children
Adult use only. Small elements can be swallowed, causing severe trauma. Keep away from children and animals.
Electronic devices
Very strong magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Dust is flammable
Powder created during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
