Pros and cons of neodymium magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- Magnets effectively defend themselves against loss of magnetization caused by foreign field sources,
- By applying a decorative coating of silver, the element gains an professional look,
- Neodymium magnets generate maximum magnetic induction on a small surface, which ensures high operational effectiveness,
- Neodymium magnets are characterized by extremely 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...
- Possibility of individual creating as well as adapting to concrete needs,
- Fundamental importance in modern technologies – they are utilized in computer drives, electric drive systems, medical devices, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in miniature devices
Disadvantages
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields 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 force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets start to 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.
- Limited ability of making threads in the magnet and complicated shapes - recommended is a housing - magnetic holder.
- Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Furthermore, tiny parts of these devices can disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price is higher than average,
Lifting parameters
Maximum magnetic pulling force – what contributes to it?
- on a block made of structural steel, optimally conducting the magnetic field
- possessing a thickness of minimum 10 mm to avoid saturation
- with a plane cleaned and smooth
- without the slightest clearance between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at room temperature
Determinants of practical lifting force of a magnet
- Distance – the presence of foreign body (paint, tape, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, 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 converting into lifting capacity.
- Material type – the best choice is pure iron steel. Stainless steels may attract less.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal factor – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity was determined by applying a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under shearing force the holding force is lower. Additionally, even a slight gap between the magnet and the plate lowers the holding force.
Warnings
Cards and drives
Equipment safety: Strong magnets can damage data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
Danger to the youngest
Only for adults. Tiny parts pose a choking risk, leading to serious injuries. Keep out of reach of kids and pets.
Finger safety
Pinching hazard: The pulling power is so great that it can result in blood blisters, pinching, and broken bones. Use thick gloves.
Magnets are brittle
Protect your eyes. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Warning for allergy sufferers
Medical facts indicate that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid touching magnets with bare hands and choose coated magnets.
Conscious usage
Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
GPS Danger
Be aware: rare earth magnets generate a field that confuses sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.
Heat warning
Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.
Do not drill into magnets
Powder produced during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.
Implant safety
For implant holders: Strong magnetic fields disrupt medical devices. Maintain at least 30 cm distance or request help to work with the magnets.
