Advantages and disadvantages of neodymium magnets.
Benefits
- They retain full power for around 10 years – the drop is just ~1% (according to analyses),
- They show high resistance to demagnetization induced by external disturbances,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- Neodymium magnets deliver maximum magnetic induction on a small area, which allows for strong attraction,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Thanks to versatility in forming and the ability to customize to specific needs,
- Versatile presence in high-tech industry – they serve a role in mass storage devices, electric drive systems, medical devices, and other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We recommend a housing - magnetic holder, due to difficulties in realizing threads inside the magnet and complex forms.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child safety. 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 cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- using a sheet made of mild steel, acting as a magnetic yoke
- whose thickness is min. 10 mm
- with an polished touching surface
- without any clearance between the magnet and steel
- during pulling in a direction vertical to the mounting surface
- at standard ambient temperature
Lifting capacity in real conditions – factors
- Gap (betwixt the magnet and the metal), since even a very small distance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Plate thickness – too thin steel causes magnetic saturation, causing part of the power to be wasted into the air.
- Plate material – low-carbon steel attracts best. Alloy admixtures decrease magnetic permeability and holding force.
- Plate texture – ground elements guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate decreases the holding force.
H&S for magnets
Skin irritation risks
A percentage of the population have a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching can result in dermatitis. It is best to wear protective gloves.
Medical interference
Patients with a ICD must keep an large gap from magnets. The magnetic field can interfere with the functioning of the implant.
Choking Hazard
NdFeB magnets are not intended for children. Swallowing multiple magnets can lead to them attracting across intestines, which poses a direct threat to life and necessitates urgent medical intervention.
Cards and drives
Powerful magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Stay away of min. 10 cm.
Respect the power
Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Machining danger
Dust produced during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Maximum temperature
Regular neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. Damage is permanent.
GPS and phone interference
A strong magnetic field negatively affects the operation of compasses in phones and navigation systems. Do not bring magnets near a smartphone to prevent damaging the sensors.
Serious injuries
Large magnets can crush fingers instantly. Never put your hand between two attracting surfaces.
Fragile material
Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
