Advantages as well as disadvantages of rare earth magnets.
Pros
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- Magnets perfectly resist against demagnetization caused by foreign field sources,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- They feature high magnetic induction at the operating surface, which affects their effectiveness,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- In view of the option of precise shaping and adaptation to custom solutions, neodymium magnets can be manufactured in a wide range of shapes and sizes, which amplifies use scope,
- Fundamental importance in modern industrial fields – they are used in HDD drives, electric drive systems, diagnostic systems, as well as modern systems.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Weaknesses
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- 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.
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Health risk to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these products can disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- using a plate made of low-carbon steel, functioning as a ideal flux conductor
- whose thickness equals approx. 10 mm
- characterized by even structure
- with total lack of distance (no coatings)
- under vertical force direction (90-degree angle)
- at conditions approx. 20°C
Lifting capacity in practice – influencing factors
- Clearance – the presence of any layer (paint, dirt, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Steel grade – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Surface quality – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Thermal factor – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was measured using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Precautions when working with NdFeB magnets
Compass and GPS
An intense magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Maintain magnets close to a device to avoid breaking the sensors.
Caution required
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Danger to pacemakers
Individuals with a heart stimulator should keep an safe separation from magnets. The magnetic field can stop the functioning of the life-saving device.
Threat to electronics
Powerful magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Dust is flammable
Powder created during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Skin irritation risks
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, cease working with magnets and use protective gear.
Operating temperature
Control the heat. Heating the magnet to high heat will destroy its magnetic structure and pulling force.
Crushing risk
Protect your hands. Two large magnets will snap together instantly with a force of massive weight, crushing everything in their path. Be careful!
Fragile material
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Impact of two magnets leads to them cracking into shards.
This is not a toy
Always keep magnets away from children. Choking hazard is high, and the consequences of magnets clamping inside the body are very dangerous.
