Strengths and weaknesses of rare earth magnets.
Advantages
- They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
- Neodymium magnets are distinguished by highly resistant to demagnetization caused by magnetic disturbances,
- Thanks to the shiny finish, the layer of Ni-Cu-Ni, gold-plated, or silver gives an clean appearance,
- Magnets are characterized by exceptionally strong magnetic induction on the surface,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures approaching 230°C and above...
- Thanks to modularity in forming and the capacity to adapt to specific needs,
- Significant place in modern technologies – they are used in magnetic memories, brushless drives, diagnostic systems, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in compact constructions
Disadvantages
- At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- We suggest cover - magnetic mount, due to difficulties in creating threads inside the magnet and complicated forms.
- Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Furthermore, tiny parts of these magnets are able to complicate diagnosis medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Holding force characteristics
Maximum lifting capacity of the magnet – what it depends on?
- using a base made of low-carbon steel, serving as a circuit closing element
- possessing a massiveness of at least 10 mm to avoid saturation
- with an ideally smooth touching surface
- with direct contact (no coatings)
- during detachment in a direction vertical to the mounting surface
- in stable room temperature
Lifting capacity in real conditions – factors
- Distance – the presence of foreign body (paint, dirt, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Cast iron may attract less.
- Smoothness – full contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was assessed using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet and the plate lowers the holding force.
Precautions when working with neodymium magnets
Health Danger
Warning for patients: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or request help to work with the magnets.
Safe distance
Device Safety: Neodymium magnets can damage data carriers and delicate electronics (heart implants, medical aids, timepieces).
GPS and phone interference
A strong magnetic field disrupts the functioning of compasses in smartphones and navigation systems. Keep magnets near a smartphone to avoid damaging the sensors.
Eye protection
NdFeB magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets leads to them shattering into small pieces.
Thermal limits
Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Allergy Warning
Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation happens, cease handling magnets and use protective gear.
Danger to the youngest
NdFeB magnets are not intended for children. Accidental ingestion of a few magnets may result in them connecting inside the digestive tract, which constitutes a direct threat to life and requires urgent medical intervention.
Combustion hazard
Powder produced during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Handling rules
Handle magnets consciously. Their powerful strength can shock even professionals. Be vigilant and respect their power.
Crushing risk
Danger of trauma: The attraction force is so immense that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.
