Pros and cons of rare earth magnets.
Apart from their strong magnetism, neodymium magnets have these key benefits:
- They do not lose magnetism, even over approximately 10 years – the decrease in lifting capacity is only ~1% (theoretically),
- Magnets perfectly protect themselves against demagnetization caused by ambient magnetic noise,
- By applying a smooth coating of nickel, the element presents an proper look,
- Magnets have maximum magnetic induction on the outer layer,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
- Thanks to the possibility of flexible molding and adaptation to specialized requirements, magnetic components can be modeled in a variety of forms and dimensions, which amplifies use scope,
- Universal use in innovative solutions – they find application in hard drives, brushless drives, precision medical tools, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in small systems
Disadvantages of NdFeB magnets:
- At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as 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 power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest a housing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these products are able to complicate diagnosis medical in case of swallowing.
- Due to expensive raw materials, their price exceeds standard values,
Maximum lifting capacity of the magnet – what it depends on?
Breakaway force was determined for the most favorable conditions, assuming:
- with the use of a yoke made of low-carbon steel, ensuring full magnetic saturation
- with a cross-section no less than 10 mm
- with a surface cleaned and smooth
- without the slightest insulating layer between the magnet and steel
- under perpendicular force vector (90-degree angle)
- in neutral thermal conditions
Practical aspects of lifting capacity – factors
During everyday use, the actual lifting capacity depends on a number of factors, presented from the most important:
- Gap (betwixt the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Material composition – not every steel attracts identically. High carbon content weaken the attraction effect.
- Smoothness – full contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
* Lifting capacity was assessed using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance {between} the magnet and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Crushing risk
Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!
Data carriers
Data protection: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).
GPS Danger
Remember: rare earth magnets produce a field that interferes with precision electronics. Maintain a safe distance from your mobile, tablet, and navigation systems.
Material brittleness
Neodymium magnets are sintered ceramics, which means they are fragile like glass. Collision of two magnets leads to them shattering into shards.
Allergy Warning
Medical facts indicate that nickel (the usual finish) is a strong allergen. If you have an allergy, refrain from direct skin contact or opt for coated magnets.
Do not drill into magnets
Mechanical processing of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Demagnetization risk
Regular neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
Adults only
Absolutely keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets connecting inside the body are tragic.
Warning for heart patients
For implant holders: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.
Caution required
Handle magnets with awareness. Their immense force can surprise even professionals. Be vigilant and respect their power.
Warning!
