Advantages and disadvantages of rare earth magnets.
Benefits
- They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
- Magnets effectively defend themselves against loss of magnetization caused by foreign field sources,
- A magnet with a metallic nickel surface has better aesthetics,
- The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of precise machining and adjusting to individual conditions,
- Versatile presence in advanced technology sectors – they serve a role in data components, electromotive mechanisms, diagnostic systems, and multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic mount, due to difficulties in creating threads inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small components of these magnets are able to disrupt the diagnostic process medical when they are in 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
Maximum magnetic pulling force – what contributes to it?
- on a plate made of structural steel, optimally conducting the magnetic flux
- with a cross-section no less than 10 mm
- characterized by even structure
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction perpendicular to the plane
- at temperature room level
Practical lifting capacity: influencing factors
- Air gap (between the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Base massiveness – insufficiently thick steel does not accept the full field, causing part of the flux to be wasted into the air.
- Chemical composition of the base – low-carbon steel attracts best. Higher carbon content lower magnetic permeability and holding force.
- Plate texture – smooth surfaces ensure maximum contact, which increases force. Rough surfaces weaken the grip.
- Temperature – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Keep away from electronics
Remember: rare earth magnets produce a field that disrupts sensitive sensors. Keep a separation from your phone, tablet, and GPS.
Eye protection
Watch out for shards. Magnets can fracture upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Respect the power
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Do not give to children
NdFeB magnets are not intended for children. Eating several magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and requires urgent medical intervention.
Electronic hazard
Device Safety: Strong magnets can damage data carriers and sensitive devices (pacemakers, medical aids, timepieces).
Do not drill into magnets
Powder created during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Warning for heart patients
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Finger safety
Risk of injury: The pulling power is so great that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.
Permanent damage
Keep cool. NdFeB magnets are sensitive to temperature. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
Metal Allergy
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness occurs, cease working with magnets and wear gloves.
