Advantages as well as disadvantages of neodymium magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They do not lose their magnetic properties even under close interference source,
- The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to look better,
- They feature high magnetic induction at the operating surface, making them more effective,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in shaping and the capacity to modify to specific needs,
- Significant place in electronics industry – they are used in HDD drives, drive modules, medical equipment, as well as complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing threads and complicated forms in magnets, we propose using a housing - magnetic mechanism.
- Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, tiny parts of these magnets can complicate diagnosis medical in case of swallowing.
- With large orders the cost of neodymium magnets is economically unviable,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a block made of mild steel, perfectly concentrating the magnetic field
- with a cross-section no less than 10 mm
- with a plane perfectly flat
- with zero gap (without paint)
- during pulling in a direction perpendicular to the plane
- at standard ambient temperature
Determinants of lifting force in real conditions
- Distance – the presence of any layer (rust, dirt, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Steel grade – the best choice is pure iron steel. Cast iron may attract less.
- Surface structure – the smoother and more polished the surface, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was measured using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
Fire warning
Fire warning: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.
Bone fractures
Danger of trauma: The pulling power is so immense that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
Keep away from children
These products are not intended for children. Swallowing several magnets may result in them pinching intestinal walls, which poses a direct threat to life and requires immediate surgery.
Metal Allergy
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction happens, immediately stop handling magnets and use protective gear.
Medical implants
Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Do not overheat magnets
Keep cool. Neodymium magnets are susceptible to heat. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
Do not underestimate power
Use magnets with awareness. Their huge power can surprise even professionals. Stay alert and respect their power.
Threat to navigation
Note: rare earth magnets generate a field that disrupts sensitive sensors. Keep a separation from your mobile, tablet, and navigation systems.
Magnetic media
Device Safety: Strong magnets can damage payment cards and sensitive devices (pacemakers, medical aids, timepieces).
Protective goggles
Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
