Strengths and weaknesses of rare earth magnets.
Benefits
- They do not lose power, even after nearly 10 years – the reduction in strength is only ~1% (according to tests),
- Magnets very well resist against loss of magnetization caused by external fields,
- A magnet with a shiny nickel surface has better aesthetics,
- Magnetic induction on the top side of the magnet turns out to be strong,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
- Possibility of individual machining as well as adapting to concrete requirements,
- Fundamental importance in modern technologies – they serve a role in data components, electromotive mechanisms, diagnostic systems, and complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in creating threads and complex shapes in magnets, we propose using casing - magnetic mechanism.
- Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices can complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the contact of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- with a thickness no less than 10 mm
- with an ideally smooth contact surface
- under conditions of no distance (metal-to-metal)
- for force applied at a right angle (in the magnet axis)
- at ambient temperature room level
Determinants of practical lifting force of a magnet
- Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Metal type – not every steel attracts identically. High carbon content worsen the attraction effect.
- Surface finish – ideal contact is obtained only on polished steel. Rough texture reduce the real contact area, reducing force.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate decreases the lifting capacity.
H&S for magnets
Bodily injuries
Pinching hazard: The pulling power is so great that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Powerful field
Handle magnets consciously. Their huge power can shock even experienced users. Be vigilant and do not underestimate their power.
Do not drill into magnets
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Avoid contact if allergic
Certain individuals suffer from a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Extended handling can result in skin redness. We suggest use protective gloves.
This is not a toy
Only for adults. Small elements can be swallowed, causing severe trauma. Store away from children and animals.
Threat to electronics
Avoid bringing magnets close to a wallet, laptop, or screen. The magnetic field can destroy these devices and wipe information from cards.
Danger to pacemakers
For implant holders: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.
Compass and GPS
Navigation devices and smartphones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Magnet fragility
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Operating temperature
Regular neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. Damage is permanent.
