Strengths and weaknesses of rare earth magnets.
Advantages
- Their magnetic field remains stable, and after approximately 10 years it drops only by ~1% (theoretically),
- They do not lose their magnetic properties even under external field action,
- A magnet with a smooth nickel surface has better aesthetics,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
- Thanks to the potential of precise shaping and adaptation to unique requirements, NdFeB magnets can be produced in a wide range of shapes and sizes, which increases their versatility,
- Versatile presence in modern technologies – they are commonly used in mass storage devices, drive modules, advanced medical instruments, and industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a strong case, 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 recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. 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 mechanism, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which gains importance in the context of child safety. Furthermore, small components of these magnets can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- using a plate made of high-permeability steel, functioning as a magnetic yoke
- whose transverse dimension equals approx. 10 mm
- characterized by lack of roughness
- with zero gap (no paint)
- under perpendicular force vector (90-degree angle)
- at ambient temperature room level
Magnet lifting force in use – key factors
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Steel thickness – too thin steel causes magnetic saturation, causing part of the flux to be lost into the air.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface structure – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was determined by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Health Danger
Patients with a heart stimulator have to maintain an safe separation from magnets. The magnetic field can interfere with the operation of the life-saving device.
Do not underestimate power
Handle magnets consciously. Their immense force can surprise even experienced users. Be vigilant and do not underestimate their power.
Threat to electronics
Very strong magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Dust is flammable
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
GPS and phone interference
Be aware: rare earth magnets generate a field that interferes with precision electronics. Maintain a separation from your mobile, tablet, and GPS.
Avoid contact if allergic
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, cease handling magnets and use protective gear.
No play value
These products are not toys. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which constitutes a critical condition and necessitates urgent medical intervention.
Magnet fragility
NdFeB magnets are ceramic materials, which means they are fragile like glass. Clashing of two magnets leads to them cracking into shards.
Crushing risk
Risk of injury: The attraction force is so great that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.
Do not overheat magnets
Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. Damage is permanent.
