Strengths and weaknesses of rare earth magnets.
Strengths
- They have stable power, and over around ten years their performance decreases symbolically – ~1% (according to theory),
- They do not lose their magnetic properties even under close interference source,
- By covering with a decorative layer of gold, the element acquires an nice look,
- Magnets have excellent magnetic induction on the outer side,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of exact forming and modifying to defined requirements,
- Significant place in advanced technology sectors – they are used in magnetic memories, motor assemblies, medical equipment, as well as industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- At strong impacts they can crack, therefore we recommend 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 power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in realizing nuts and complicated forms in magnets, we propose using casing - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. Furthermore, small components of these magnets are able to complicate diagnosis medical when they are in the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what contributes to it?
- using a base made of low-carbon steel, serving as a circuit closing element
- whose transverse dimension is min. 10 mm
- with a plane cleaned and smooth
- under conditions of no distance (metal-to-metal)
- during pulling in a direction vertical to the mounting surface
- at temperature room level
Practical aspects of lifting capacity – factors
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Base massiveness – too thin sheet does not close the flux, causing part of the flux to be lost into the air.
- Plate material – mild steel attracts best. Alloy steels lower magnetic properties and lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
- Temperature influence – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Safe handling of NdFeB magnets
Health Danger
Medical warning: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Data carriers
Do not bring magnets close to a purse, laptop, or screen. The magnetic field can destroy these devices and wipe information from cards.
Threat to navigation
Navigation devices and mobile phones are highly susceptible to magnetic fields. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Respect the power
Be careful. Neodymium magnets attract from a distance and connect with massive power, often quicker than you can react.
Warning for allergy sufferers
Medical facts indicate that nickel (standard magnet coating) is a strong allergen. If you have an allergy, prevent touching magnets with bare hands or select coated magnets.
Hand protection
Big blocks can break fingers instantly. Under no circumstances put your hand between two attracting surfaces.
Permanent damage
Keep cool. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Dust is flammable
Drilling and cutting of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Beware of splinters
Beware of splinters. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
Product not for children
Product intended for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Store away from children and animals.
