Pros and cons of rare earth magnets.
Strengths
- They retain magnetic properties for almost ten years – the drop is just ~1% (in theory),
- They are extremely resistant to demagnetization induced by external disturbances,
- In other words, due to the reflective finish of silver, the element gains a professional look,
- The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
- Thanks to versatility in constructing and the capacity to modify to unusual requirements,
- Wide application in high-tech industry – they are commonly used in magnetic memories, motor assemblies, precision medical tools, as well as industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- At strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- We recommend cover - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated shapes.
- Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these devices can disrupt the diagnostic process medical after entering the body.
- With large orders the cost of neodymium magnets is a challenge,
Pull force analysis
Maximum magnetic pulling force – what contributes to it?
- using a plate made of low-carbon steel, serving as a ideal flux conductor
- possessing a thickness of minimum 10 mm to ensure full flux closure
- characterized by lack of roughness
- with direct contact (without paint)
- under perpendicular force vector (90-degree angle)
- in stable room temperature
Determinants of practical lifting force of a magnet
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Plate material – low-carbon steel gives the best results. Higher carbon content lower magnetic permeability and holding force.
- Surface finish – full contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was measured with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet and the plate lowers the lifting capacity.
Safety rules for work with NdFeB magnets
Danger to pacemakers
People with a heart stimulator must maintain an safe separation from magnets. The magnetism can interfere with the operation of the life-saving device.
Danger to the youngest
Adult use only. Tiny parts can be swallowed, leading to serious injuries. Store out of reach of kids and pets.
Allergy Warning
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness appears, cease working with magnets and use protective gear.
Caution required
Handle magnets with awareness. Their immense force can surprise even professionals. Be vigilant and respect their force.
Shattering risk
Beware of splinters. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Do not overheat magnets
Monitor thermal conditions. Heating the magnet to high heat will ruin its properties and pulling force.
Compass and GPS
A powerful magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Maintain magnets near a device to avoid breaking the sensors.
Threat to electronics
Very strong magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.
Bone fractures
Pinching hazard: The pulling power is so immense that it can result in hematomas, pinching, and broken bones. Use thick gloves.
Dust explosion hazard
Mechanical processing of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
