Advantages as well as disadvantages of rare earth magnets.
Benefits
- Their magnetic field is durable, and after approximately ten years it decreases only by ~1% (according to research),
- They do not lose their magnetic properties even under strong external field,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- In view of the potential of free forming and adaptation to individualized projects, NdFeB magnets can be modeled in a wide range of forms and dimensions, which makes them more universal,
- Key role in modern technologies – they are utilized in mass storage devices, brushless drives, medical equipment, and multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Weaknesses
- At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power 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
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of producing threads in the magnet and complicated shapes - preferred is a housing - magnetic holder.
- Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these products can disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what affects it?
- on a block made of structural steel, perfectly concentrating the magnetic field
- with a cross-section no less than 10 mm
- with an polished touching surface
- with total lack of distance (without coatings)
- for force acting at a right angle (pull-off, not shear)
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Gap (betwixt the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Plate thickness – too thin steel does not close the flux, causing part of the power to be lost to the other side.
- Material composition – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
- Smoothness – ideal contact is obtained only on polished steel. Rough texture reduce the real contact area, reducing force.
- Thermal environment – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, however under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the holding force.
Safe handling of neodymium magnets
Power loss in heat
Avoid heat. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Electronic hazard
Device Safety: Strong magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, timepieces).
Threat to navigation
A powerful magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Maintain magnets near a smartphone to prevent damaging the sensors.
Product not for children
Product intended for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep away from kids and pets.
Medical interference
Life threat: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Fire risk
Machining of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Metal Allergy
It is widely known that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, avoid direct skin contact or choose versions in plastic housing.
Bone fractures
Danger of trauma: The pulling power is so great that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.
Shattering risk
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets leads to them breaking into small pieces.
Do not underestimate power
Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
