Pros and cons of rare earth magnets.
Advantages
- Their strength is durable, and after approximately 10 years it decreases only by ~1% (according to research),
- They do not lose their magnetic properties even under close interference source,
- A magnet with a shiny silver surface is more attractive,
- Neodymium magnets ensure maximum magnetic induction on a small surface, which allows for strong attraction,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures reaching 230°C and above...
- Possibility of custom creating as well as modifying to precise applications,
- Versatile presence in advanced technology sectors – they serve a role in data components, drive modules, medical devices, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in miniature devices
Limitations
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating nuts and complicated shapes in magnets, we recommend using cover - magnetic mount.
- Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, tiny parts of these magnets are able to disrupt the diagnostic process medical after entering the body.
- Due to expensive raw materials, their price is higher than average,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what contributes to it?
- on a block made of structural steel, effectively closing the magnetic flux
- with a cross-section minimum 10 mm
- with a plane cleaned and smooth
- with total lack of distance (without paint)
- for force applied at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Gap between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Stainless steels may attract less.
- Surface finish – ideal contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was measured by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet’s surface and the plate lowers the holding force.
Warnings
Handling guide
Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Sensitization to coating
It is widely known that nickel (the usual finish) is a common allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or choose versions in plastic housing.
Do not overheat magnets
Keep cool. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Eye protection
Neodymium magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets will cause them cracking into shards.
Electronic devices
Very strong magnetic fields can erase data on payment cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Dust explosion hazard
Powder generated during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Medical implants
Medical warning: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Bone fractures
Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Keep away from electronics
An intense magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Maintain magnets close to a device to prevent breaking the sensors.
Keep away from children
Adult use only. Tiny parts can be swallowed, leading to severe trauma. Keep out of reach of kids and pets.
