Pros and cons of neodymium magnets.
Strengths
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
- Neodymium magnets are exceptionally resistant to loss of magnetic properties caused by external interference,
- A magnet with a smooth gold surface looks better,
- The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
- Possibility of exact forming as well as adjusting to individual applications,
- Wide application in modern industrial fields – they are utilized in data components, electric drive systems, medical devices, and complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Limited ability of making threads in the magnet and complicated forms - preferred is cover - mounting mechanism.
- Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. Additionally, small components of these devices are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what affects it?
- using a plate made of low-carbon steel, acting as a ideal flux conductor
- whose thickness equals approx. 10 mm
- with an ideally smooth contact surface
- with direct contact (without paint)
- under axial force vector (90-degree angle)
- in stable room temperature
Determinants of practical lifting force of a magnet
- Clearance – the presence of any layer (rust, dirt, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Plate material – mild steel gives the best results. Alloy steels lower magnetic properties and holding force.
- Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
- Thermal factor – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
H&S for magnets
Finger safety
Big blocks can crush fingers in a fraction of a second. Never place your hand betwixt two attracting surfaces.
Mechanical processing
Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Protect data
Equipment safety: Neodymium magnets can damage payment cards and sensitive devices (heart implants, medical aids, timepieces).
Magnetic interference
Note: neodymium magnets generate a field that interferes with sensitive sensors. Maintain a separation from your mobile, tablet, and GPS.
Implant safety
Warning for patients: Powerful magnets affect medical devices. Maintain at least 30 cm distance or request help to handle the magnets.
Shattering risk
Protect your eyes. Magnets can explode upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Avoid contact if allergic
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If redness occurs, immediately stop working with magnets and use protective gear.
No play value
Strictly keep magnets away from children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are life-threatening.
Respect the power
Handle magnets with awareness. Their powerful strength can surprise even professionals. Plan your moves and do not underestimate their power.
Permanent damage
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. Damage is permanent.
