Pros as well as cons of rare earth magnets.
Advantages
- Their strength remains stable, and after around ten years it decreases only by ~1% (according to research),
- They have excellent resistance to magnetism drop as a result of opposing magnetic fields,
- The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to look better,
- Magnetic induction on the top side of the magnet remains maximum,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of detailed machining and adapting to concrete requirements,
- Key role in future technologies – they are utilized in hard drives, electromotive mechanisms, advanced medical instruments, and technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- 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 recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Due to limitations in producing nuts and complex shapes in magnets, we recommend using cover - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, if swallowed, which gains importance in the context of child safety. Additionally, small elements of these magnets are able to be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting force for a neodymium magnet – what contributes to it?
- on a base made of mild steel, perfectly concentrating the magnetic flux
- with a cross-section of at least 10 mm
- with an polished touching surface
- under conditions of no distance (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Practical aspects of lifting capacity – factors
- Distance – existence of foreign body (paint, tape, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (typically 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).
- Chemical composition of the base – mild steel gives the best results. Alloy steels reduce magnetic permeability and lifting capacity.
- Surface finish – full contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Temperature influence – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet and the plate decreases the load capacity.
Safety rules for work with neodymium magnets
Nickel allergy
Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction happens, immediately stop working with magnets and use protective gear.
Product not for children
Product intended for adults. Tiny parts pose a choking risk, causing serious injuries. Store out of reach of children and animals.
Fire risk
Dust created during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
GPS and phone interference
An intense magnetic field negatively affects the operation of compasses in smartphones and GPS navigation. Keep magnets close to a device to prevent breaking the sensors.
Permanent damage
Standard neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Cards and drives
Powerful magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
Eye protection
Neodymium magnets are sintered ceramics, which means they are very brittle. Collision of two magnets leads to them cracking into small pieces.
Danger to pacemakers
Life threat: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Pinching danger
Watch your fingers. Two powerful magnets will snap together immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!
Conscious usage
Handle with care. Rare earth magnets act from a distance and snap with huge force, often quicker than you can move away.
