Pros as well as cons of neodymium magnets.
Strengths
- They retain full power for almost 10 years – the loss is just ~1% (in theory),
- They feature excellent resistance to magnetism drop due to external magnetic sources,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to look better,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
- Possibility of individual forming as well as optimizing to precise conditions,
- Wide application in electronics industry – they are commonly used in hard drives, motor assemblies, precision medical tools, also other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- 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
- Due to limitations in producing nuts and complicated forms in magnets, we recommend using cover - magnetic mechanism.
- Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these magnets can disrupt the diagnostic process medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what it depends on?
- on a block made of structural steel, effectively closing the magnetic flux
- with a thickness no less than 10 mm
- with a plane cleaned and smooth
- under conditions of gap-free contact (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- in neutral thermal conditions
Key elements affecting lifting force
- Distance – the presence of any layer (rust, dirt, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Material composition – not every steel reacts the same. High carbon content worsen the attraction effect.
- Smoothness – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Temperature influence – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate reduces the holding force.
Warnings
Respect the power
Use magnets with awareness. Their powerful strength can surprise even professionals. Be vigilant and respect their power.
Warning for heart patients
For implant holders: Strong magnetic fields affect medical devices. Maintain at least 30 cm distance or ask another person to handle the magnets.
Fragile material
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Choking Hazard
These products are not intended for children. Accidental ingestion of several magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and necessitates urgent medical intervention.
Maximum temperature
Monitor thermal conditions. Heating the magnet to high heat will destroy its magnetic structure and pulling force.
Phone sensors
An intense magnetic field negatively affects the operation of magnetometers in phones and navigation systems. Do not bring magnets near a smartphone to prevent breaking the sensors.
Allergy Warning
Certain individuals experience a sensitization to Ni, which is the typical protective layer for neodymium magnets. Frequent touching may cause a rash. We recommend wear safety gloves.
Hand protection
Mind your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Protect data
Device Safety: Neodymium magnets can damage payment cards and delicate electronics (heart implants, medical aids, timepieces).
Mechanical processing
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
