Advantages as well as disadvantages of rare earth magnets.
Strengths
- They have constant strength, and over around ten years their performance decreases symbolically – ~1% (in testing),
- They are noted for resistance to demagnetization induced by external field influence,
- A magnet with a shiny gold surface has an effective appearance,
- The surface of neodymium magnets generates a powerful magnetic field – this is one of their assets,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to flexibility in forming and the capacity to modify to unusual requirements,
- Key role in modern industrial fields – they serve a role in data components, electromotive mechanisms, medical devices, also technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 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 resistant to moisture, in case of application outdoors
- Due to limitations in realizing nuts and complicated forms in magnets, we recommend using casing - magnetic mechanism.
- Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these devices can complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum magnetic pulling force – what affects it?
- on a base made of structural steel, optimally conducting the magnetic field
- whose thickness reaches at least 10 mm
- with an ideally smooth contact surface
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at temperature room level
Key elements affecting lifting force
- Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Metal type – not every steel attracts identically. High carbon content weaken 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 conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, however under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the load capacity.
H&S for magnets
Fire warning
Dust produced during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Thermal limits
Regular neodymium magnets (grade N) lose power when the temperature exceeds 80°C. Damage is permanent.
Risk of cracking
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
Serious injuries
Protect your hands. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!
Nickel coating and allergies
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, prevent direct skin contact and choose encased magnets.
Data carriers
Powerful magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Adults only
Always keep magnets away from children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are tragic.
Life threat
People with a ICD must keep an large gap from magnets. The magnetic field can interfere with the operation of the implant.
Compass and GPS
Remember: neodymium magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your mobile, device, and navigation systems.
Do not underestimate power
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
