Strengths and weaknesses of rare earth magnets.
Strengths
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
- They have excellent resistance to magnetic field loss when exposed to external fields,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to look better,
- Magnetic induction on the working part of the magnet turns out to be exceptional,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Due to the option of precise forming and adaptation to specialized projects, NdFeB magnets can be created in a wide range of shapes and sizes, which increases their versatility,
- Significant place in innovative solutions – they are commonly used in HDD drives, electric motors, medical equipment, as well as modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Due to limitations in realizing nuts and complex shapes in magnets, we propose using a housing - magnetic holder.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Furthermore, tiny parts of these products can be problematic in diagnostics medical after entering the body.
- Due to complex production process, their price exceeds standard values,
Pull force analysis
Maximum holding power of the magnet – what affects it?
- on a plate made of structural steel, optimally conducting the magnetic field
- possessing a massiveness of min. 10 mm to avoid saturation
- with a plane perfectly flat
- with total lack of distance (no paint)
- during detachment in a direction vertical to the mounting surface
- in neutral thermal conditions
Lifting capacity in practice – influencing factors
- Gap (betwixt the magnet and the plate), since even a very small distance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Material type – ideal substrate is pure iron steel. Cast iron may attract less.
- Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
- Temperature – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
H&S for magnets
Impact on smartphones
Note: neodymium magnets produce a field that confuses sensitive sensors. Keep a safe distance from your phone, tablet, and navigation systems.
Machining danger
Powder created during machining of magnets is combustible. Do not drill into magnets unless you are an expert.
Protect data
Device Safety: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, timepieces).
Health Danger
Warning for patients: Strong magnetic fields disrupt medical devices. Maintain at least 30 cm distance or request help to work with the magnets.
This is not a toy
NdFeB magnets are not toys. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and necessitates immediate surgery.
Serious injuries
Risk of injury: The pulling power is so immense that it can cause hematomas, pinching, and broken bones. Use thick gloves.
Handling rules
Be careful. Neodymium magnets attract from a long distance and snap with huge force, often faster than you can react.
Power loss in heat
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. The loss of strength is permanent.
Metal Allergy
It is widely known that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, refrain from direct skin contact and opt for coated magnets.
Eye protection
Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
