Strengths and weaknesses of neodymium magnets.
Advantages
- Their strength is durable, and after approximately 10 years it drops only by ~1% (theoretically),
- Magnets very well protect themselves against demagnetization caused by ambient magnetic noise,
- The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnets are distinguished by maximum magnetic induction on the outer side,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Due to the option of free forming and customization to unique projects, magnetic components can be created in a broad palette of shapes and sizes, which amplifies use scope,
- Versatile presence in modern industrial fields – they find application in data components, electric motors, advanced medical instruments, and industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Disadvantages
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing nuts and complex forms in magnets, we propose using a housing - magnetic mechanism.
- Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these products are able to complicate diagnosis medical in case of swallowing.
- With large orders the cost of neodymium magnets is a challenge,
Holding force characteristics
Highest magnetic holding force – what it depends on?
- on a base made of mild steel, perfectly concentrating the magnetic field
- whose thickness reaches at least 10 mm
- with an ideally smooth contact surface
- with direct contact (without coatings)
- for force acting at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Key elements affecting lifting force
- Distance – existence of any layer (rust, tape, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Load vector – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate decreases the load capacity.
Warnings
Serious injuries
Risk of injury: The attraction force is so immense that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.
Thermal limits
Avoid heat. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, look for HT versions (H, SH, UH).
Eye protection
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
Nickel coating and allergies
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, immediately stop working with magnets and wear gloves.
Dust is flammable
Dust generated during machining of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Keep away from electronics
Note: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a separation from your phone, tablet, and GPS.
Handling rules
Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.
No play value
Strictly store magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are life-threatening.
Keep away from computers
Data protection: Strong magnets can damage data carriers and delicate electronics (heart implants, medical aids, timepieces).
Health Danger
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
