Pros as well as cons of neodymium magnets.
Benefits
- They do not lose magnetism, even over approximately 10 years – the drop in strength is only ~1% (according to tests),
- They retain their magnetic properties even under external field action,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to look better,
- Magnets have extremely high magnetic induction on the surface,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Possibility of custom forming as well as adjusting to complex applications,
- Fundamental importance in high-tech industry – they are used in hard drives, electric motors, diagnostic systems, also modern systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and 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
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- Limited possibility of creating threads in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
- Possible danger resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the context of child safety. Additionally, small elements of these magnets can complicate diagnosis medical after entering the body.
- With mass production the cost of neodymium magnets can be a barrier,
Lifting parameters
Highest magnetic holding force – what contributes to it?
- with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
- possessing a massiveness of minimum 10 mm to avoid saturation
- characterized by lack of roughness
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction perpendicular to the plane
- in temp. approx. 20°C
Determinants of practical lifting force of a magnet
- Clearance – existence of foreign body (rust, tape, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet holds much less (typically approx. 20-30% of nominal force).
- Steel thickness – too thin sheet causes magnetic saturation, causing part of the flux to be escaped to the other side.
- Steel type – mild steel attracts best. Alloy admixtures decrease magnetic properties and lifting capacity.
- Surface quality – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was determined with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet and the plate decreases the holding force.
Caution required
Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Swallowing risk
Only for adults. Tiny parts pose a choking risk, leading to serious injuries. Store away from children and animals.
Heat sensitivity
Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. This process is irreversible.
Material brittleness
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Skin irritation risks
Nickel alert: The nickel-copper-nickel coating contains nickel. If redness appears, immediately stop handling magnets and use protective gear.
Warning for heart patients
For implant holders: Powerful magnets affect medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
Data carriers
Equipment safety: Strong magnets can ruin payment cards and delicate electronics (heart implants, medical aids, timepieces).
Pinching danger
Large magnets can smash fingers in a fraction of a second. Under no circumstances put your hand betwixt two attracting surfaces.
Magnetic interference
Be aware: neodymium magnets generate a field that interferes with sensitive sensors. Maintain a separation from your phone, device, and navigation systems.
Combustion hazard
Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.
