Pros as well as cons of neodymium magnets.
Benefits
- Their power is maintained, and after around 10 years it drops only by ~1% (according to research),
- Magnets very well protect themselves against loss of magnetization caused by foreign field sources,
- By covering with a shiny coating of gold, the element acquires an nice look,
- They feature high magnetic induction at the operating surface, which increases their power,
- 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...
- Possibility of individual creating as well as modifying to concrete conditions,
- Significant place in advanced technology sectors – they are utilized in hard drives, brushless drives, advanced medical instruments, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in miniature devices
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength 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
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Limited possibility of making threads in the magnet and complicated forms - recommended is casing - magnetic holder.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these magnets are able to complicate diagnosis medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Holding force characteristics
Maximum lifting capacity of the magnet – what contributes to it?
- on a base made of structural steel, perfectly concentrating the magnetic flux
- with a thickness minimum 10 mm
- with an ground contact surface
- under conditions of ideal adhesion (metal-to-metal)
- under vertical force vector (90-degree angle)
- at conditions approx. 20°C
Practical aspects of lifting capacity – factors
- Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Steel thickness – insufficiently thick steel does not close the flux, causing part of the flux to be wasted to the other side.
- Material type – the best choice is pure iron steel. Hardened steels may attract less.
- Surface finish – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal environment – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, whereas under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
H&S for magnets
GPS Danger
Navigation devices and mobile phones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can decalibrate the sensors in your phone.
Crushing force
Big blocks can smash fingers instantly. Never place your hand betwixt two strong magnets.
Do not give to children
Neodymium magnets are not intended for children. Eating multiple magnets may result in them pinching intestinal walls, which poses a critical condition and requires urgent medical intervention.
Magnets are brittle
Neodymium magnets are ceramic materials, meaning they are very brittle. Impact of two magnets will cause them shattering into small pieces.
Power loss in heat
Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. Damage is permanent.
Warning for heart patients
Individuals with a pacemaker should maintain an safe separation from magnets. The magnetic field can stop the operation of the life-saving device.
Conscious usage
Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Warning for allergy sufferers
It is widely known that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, refrain from direct skin contact or opt for versions in plastic housing.
Machining danger
Dust created during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Safe distance
Very strong magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.
