Advantages and disadvantages of Nd2Fe14B magnets.
Pros
- They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
- They possess excellent resistance to magnetism drop when exposed to external magnetic sources,
- In other words, due to the aesthetic surface of silver, the element gains visual value,
- They are known for high magnetic induction at the operating surface, which improves attraction properties,
- 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...
- Possibility of individual forming as well as modifying to concrete applications,
- Wide application in future technologies – they are utilized in computer drives, electromotive mechanisms, precision medical tools, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in miniature devices
Cons
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets decrease their power 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
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited possibility of producing threads in the magnet and complex forms - recommended is a housing - magnet mounting.
- Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these devices are able to disrupt the diagnostic process medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Pull force analysis
Best holding force of the magnet in ideal parameters – what affects it?
- with the contact of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an ground touching surface
- under conditions of no distance (metal-to-metal)
- during pulling in a direction vertical to the mounting surface
- at ambient temperature room level
Magnet lifting force in use – key factors
- Gap between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Steel thickness – too thin sheet causes magnetic saturation, causing part of the power to be escaped into the air.
- Plate material – low-carbon steel attracts best. Alloy steels reduce magnetic permeability and holding force.
- Smoothness – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was assessed with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet and the plate decreases the holding force.
H&S for magnets
Finger safety
Big blocks can break fingers instantly. Never put your hand between two strong magnets.
Handling rules
Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Threat to electronics
Avoid bringing magnets close to a purse, computer, or screen. The magnetic field can destroy these devices and wipe information from cards.
Fragile material
Protect your eyes. Magnets can fracture upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
Product not for children
Neodymium magnets are not intended for children. Eating a few magnets can lead to them pinching intestinal walls, which poses a severe health hazard and necessitates urgent medical intervention.
Metal Allergy
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, cease working with magnets and wear gloves.
Precision electronics
An intense magnetic field interferes with the operation of magnetometers in phones and navigation systems. Do not bring magnets near a smartphone to avoid breaking the sensors.
Danger to pacemakers
Warning for patients: Strong magnetic fields affect electronics. Keep minimum 30 cm distance or request help to handle the magnets.
Mechanical processing
Dust created during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Permanent damage
Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
