Strengths and weaknesses of rare earth magnets.
Advantages
- They do not lose magnetism, even after nearly 10 years – the reduction in strength is only ~1% (according to tests),
- Neodymium magnets are remarkably resistant to magnetic field loss caused by external magnetic fields,
- In other words, due to the reflective surface of nickel, the element looks attractive,
- Magnets possess impressive magnetic induction on the active area,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of precise shaping as well as adjusting to specific requirements,
- Fundamental importance in modern technologies – they find application in hard drives, electric motors, medical devices, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in small systems
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Due to limitations in realizing threads and complex shapes in magnets, we propose using casing - magnetic mount.
- Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, tiny parts of these magnets are able to disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what it depends on?
- using a sheet made of low-carbon steel, functioning as a circuit closing element
- with a thickness minimum 10 mm
- with an ground touching surface
- without any clearance between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at temperature approx. 20 degrees Celsius
Impact of factors on magnetic holding capacity in practice
- Clearance – existence of foreign body (paint, dirt, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Steel thickness – too thin plate does not close the flux, causing part of the flux to be escaped to the other side.
- Material type – the best choice is high-permeability steel. Hardened steels may attract less.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature influence – hot environment reduces magnetic field. Too high temperature can permanently damage the magnet.
Lifting capacity was determined with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet and the plate decreases the holding force.
Safety rules for work with neodymium magnets
Machining danger
Powder produced during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Caution required
Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.
This is not a toy
These products are not intended for children. Eating several magnets can lead to them attracting across intestines, which poses a direct threat to life and necessitates immediate surgery.
Finger safety
Risk of injury: The attraction force is so immense that it can result in hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Precision electronics
A powerful magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Keep magnets near a smartphone to prevent breaking the sensors.
Electronic hazard
Equipment safety: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).
Beware of splinters
Neodymium magnets are ceramic materials, which means they are very brittle. Impact of two magnets leads to them cracking into small pieces.
Danger to pacemakers
Medical warning: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Maximum temperature
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.
Allergic reactions
Studies show that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, refrain from direct skin contact and opt for coated magnets.
