Advantages as well as disadvantages of rare earth magnets.
Pros
- They do not lose strength, even during approximately ten years – the drop in power is only ~1% (according to tests),
- They do not lose their magnetic properties even under close interference source,
- A magnet with a metallic gold surface has an effective appearance,
- Magnetic induction on the top side of the magnet remains extremely intense,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures reaching 230°C and above...
- Thanks to freedom in forming and the capacity to adapt to individual projects,
- Significant place in modern technologies – they find application in computer drives, brushless drives, medical devices, and multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating threads and complex shapes in magnets, we recommend using a housing - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, small components of these products are able to complicate diagnosis medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- with the contact of a yoke made of special test steel, ensuring full magnetic saturation
- whose thickness reaches at least 10 mm
- with an ground contact surface
- with zero gap (without coatings)
- during detachment in a direction vertical to the plane
- at standard ambient temperature
Lifting capacity in practice – influencing factors
- Distance (betwixt the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Angle of force application – highest force is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Steel type – mild steel attracts best. Alloy admixtures lower magnetic properties and holding force.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
- Temperature influence – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Precautions when working with neodymium magnets
Data carriers
Device Safety: Neodymium magnets can damage payment cards and delicate electronics (heart implants, hearing aids, timepieces).
Protective goggles
Neodymium magnets are ceramic materials, which means they are fragile like glass. Clashing of two magnets leads to them cracking into small pieces.
Medical interference
For implant holders: Strong magnetic fields affect electronics. Keep minimum 30 cm distance or request help to handle the magnets.
Operating temperature
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
Dust is flammable
Fire hazard: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.
Magnetic interference
Remember: neodymium magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.
Nickel coating and allergies
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness occurs, immediately stop working with magnets and use protective gear.
Crushing risk
Pinching hazard: The attraction force is so immense that it can result in hematomas, crushing, and even bone fractures. Use thick gloves.
Product not for children
Adult use only. Small elements can be swallowed, leading to serious injuries. Keep away from children and animals.
Handling rules
Use magnets with awareness. Their powerful strength can surprise even professionals. Stay alert and respect their force.
