Strengths and weaknesses of rare earth magnets.
Benefits
- They do not lose power, even during around 10 years – the decrease in lifting capacity is only ~1% (based on measurements),
- Magnets effectively resist against loss of magnetization caused by external fields,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnets are characterized by excellent magnetic induction on the outer side,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures approaching 230°C and above...
- Possibility of custom machining as well as adapting to defined conditions,
- Key role in modern technologies – they serve a role in hard drives, drive modules, precision medical tools, and complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise 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 stable to moisture, when using outdoors
- We recommend casing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complex shapes.
- Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance 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 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
Highest magnetic holding force – what it depends on?
- on a plate made of mild steel, perfectly concentrating the magnetic flux
- whose thickness is min. 10 mm
- with an ideally smooth touching surface
- with zero gap (no paint)
- under perpendicular application of breakaway force (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Clearance – the presence of foreign body (paint, tape, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Plate material – low-carbon steel attracts best. Higher carbon content decrease magnetic permeability and holding force.
- Smoothness – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature – heating the magnet results in weakening of force. Check the thermal limit for a given model.
Lifting capacity was determined by applying a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.
H&S for magnets
Physical harm
Pinching hazard: The attraction force is so great that it can result in blood blisters, pinching, and broken bones. Use thick gloves.
Do not overheat magnets
Regular neodymium magnets (N-type) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
GPS Danger
A strong magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Keep magnets near a smartphone to avoid breaking the sensors.
Conscious usage
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Do not give to children
NdFeB magnets are not toys. Eating a few magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and requires immediate surgery.
Do not drill into magnets
Dust produced during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Electronic hazard
Intense magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Warning for allergy sufferers
Some people suffer from a sensitization to Ni, which is the common plating for neodymium magnets. Extended handling may cause a rash. It is best to wear safety gloves.
Life threat
Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
Magnet fragility
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
