Advantages and disadvantages of rare earth magnets.
Advantages
- They do not lose power, even during around 10 years – the drop in strength is only ~1% (according to tests),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- By covering with a shiny layer of gold, the element has an aesthetic look,
- Magnets are characterized by exceptionally strong magnetic induction on the active area,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Thanks to modularity in designing and the capacity to customize to individual projects,
- Key role in future technologies – they are commonly used in mass storage devices, electric drive systems, diagnostic systems, also multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
- 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.
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated forms.
- Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small elements of these magnets are able to be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what it depends on?
- using a plate made of low-carbon steel, functioning as a magnetic yoke
- whose thickness equals approx. 10 mm
- characterized by lack of roughness
- under conditions of ideal adhesion (surface-to-surface)
- under axial force vector (90-degree angle)
- in neutral thermal conditions
What influences lifting capacity in practice
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Base massiveness – insufficiently thick steel does not close the flux, causing part of the power to be lost to the other side.
- Material composition – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal environment – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet and the plate reduces the holding force.
Safe handling of NdFeB magnets
Medical interference
Patients with a ICD should keep an large gap from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Fire warning
Powder produced during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.
GPS and phone interference
A powerful magnetic field interferes with the functioning of compasses in phones and navigation systems. Keep magnets close to a device to avoid breaking the sensors.
Maximum temperature
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Skin irritation risks
Some people experience a sensitization to Ni, which is the standard coating for neodymium magnets. Extended handling can result in skin redness. We suggest wear protective gloves.
Product not for children
Strictly keep magnets away from children. Choking hazard is significant, and the consequences of magnets clamping inside the body are very dangerous.
Crushing risk
Big blocks can smash fingers instantly. Under no circumstances place your hand betwixt two attracting surfaces.
Handling guide
Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Magnets are brittle
Protect your eyes. Magnets can explode upon violent connection, launching sharp fragments into the air. Wear goggles.
Electronic devices
Powerful magnetic fields can erase data on credit cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
