Advantages and disadvantages of neodymium magnets.
Advantages
- They do not lose magnetism, even during nearly ten years – the decrease in power is only ~1% (according to tests),
- Magnets perfectly protect themselves against loss of magnetization caused by ambient magnetic noise,
- A magnet with a metallic nickel surface has an effective appearance,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to modularity in designing and the capacity to customize to specific needs,
- Versatile presence in high-tech industry – they are commonly used in computer drives, drive modules, medical devices, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in compact constructions
Limitations
- At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 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 prevent oxidation and corrosion.
- We recommend cover - magnetic holder, due to difficulties in producing nuts inside the magnet and complex forms.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these products are able to be problematic in diagnostics medical when they are in the body.
- With large orders the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum lifting capacity of the magnet – what it depends on?
- using a base made of low-carbon steel, functioning as a ideal flux conductor
- possessing a massiveness of min. 10 mm to ensure full flux closure
- characterized by even structure
- without any air gap between the magnet and steel
- during pulling in a direction perpendicular to the mounting surface
- at temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Space between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Plate thickness – too thin steel does not close the flux, causing part of the flux to be lost to the other side.
- Steel grade – ideal substrate is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Surface finish – full contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was measured with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate reduces the holding force.
Warnings
Safe operation
Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.
Power loss in heat
Avoid heat. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Adults only
Absolutely store magnets out of reach of children. Ingestion danger is high, and the effects of magnets clamping inside the body are tragic.
Crushing force
Protect your hands. Two powerful magnets will join immediately with a force of massive weight, crushing everything in their path. Be careful!
Fragile material
NdFeB magnets are ceramic materials, meaning they are very brittle. Impact of two magnets leads to them shattering into shards.
Allergy Warning
Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, cease working with magnets and use protective gear.
Safe distance
Very strong magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Stay away of min. 10 cm.
Dust explosion hazard
Fire warning: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.
Warning for heart patients
For implant holders: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or request help to handle the magnets.
GPS Danger
A strong magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Maintain magnets near a device to prevent damaging the sensors.
