Advantages and disadvantages of rare earth magnets.
Advantages
- They do not lose strength, even over approximately ten years – the reduction in power is only ~1% (based on measurements),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- A magnet with a smooth silver surface is more attractive,
- They show high magnetic induction at the operating surface, making them more effective,
- 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...
- Thanks to flexibility in shaping and the capacity to modify to complex applications,
- Key role in innovative solutions – they serve a role in data components, electromotive mechanisms, diagnostic systems, also other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complex shapes in magnets, we recommend using casing - magnetic mount.
- Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small components of these devices are able to be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum lifting force for a neodymium magnet – what it depends on?
- with the contact of a yoke made of special test steel, ensuring full magnetic saturation
- whose thickness is min. 10 mm
- with a surface free of scratches
- without the slightest clearance between the magnet and steel
- under axial force vector (90-degree angle)
- at room temperature
Impact of factors on magnetic holding capacity in practice
- Gap between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Alloy admixtures reduce magnetic properties and lifting capacity.
- Base smoothness – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was determined using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with neodymium magnets
Serious injuries
Large magnets can crush fingers instantly. Under no circumstances place your hand between two strong magnets.
Allergic reactions
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If redness happens, immediately stop handling magnets and use protective gear.
Electronic devices
Powerful magnetic fields can destroy records on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Handling guide
Be careful. Neodymium magnets attract from a distance and connect with massive power, often quicker than you can move away.
Implant safety
Patients with a ICD must keep an large gap from magnets. The magnetism can interfere with the functioning of the life-saving device.
GPS Danger
Note: rare earth magnets generate a field that interferes with sensitive sensors. Maintain a separation from your phone, device, and GPS.
Demagnetization risk
Keep cool. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Dust is flammable
Fire warning: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.
Eye protection
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Choking Hazard
NdFeB magnets are not intended for children. Accidental ingestion of a few magnets may result in them connecting inside the digestive tract, which poses a critical condition and necessitates urgent medical intervention.
