Advantages and disadvantages of neodymium magnets.
Pros
- They retain full power for almost 10 years – the loss is just ~1% (in theory),
- Magnets very well defend themselves against loss of magnetization caused by ambient magnetic noise,
- By covering with a decorative coating of silver, the element has an proper look,
- The surface of neodymium magnets generates a powerful magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to versatility in designing and the ability to customize to unusual requirements,
- Wide application in modern industrial fields – they are commonly used in mass storage devices, brushless drives, advanced medical instruments, and modern systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Cons
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of creating nuts in the magnet and complex forms - preferred is a housing - mounting mechanism.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child safety. Furthermore, small components of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- Due to complex production process, their price is higher than average,
Holding force characteristics
Highest magnetic holding force – what it depends on?
- with the contact of a sheet made of low-carbon steel, ensuring maximum field concentration
- possessing a thickness of min. 10 mm to ensure full flux closure
- with a plane cleaned and smooth
- without any clearance between the magnet and steel
- during pulling in a direction perpendicular to the plane
- at ambient temperature room level
Practical lifting capacity: influencing factors
- Gap (betwixt the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Material type – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface quality – the more even the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Temperature – heating the magnet causes a temporary drop of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with neodymium magnets
Caution required
Use magnets with awareness. Their huge power can shock even experienced users. Plan your moves and do not underestimate their power.
Mechanical processing
Mechanical processing of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Safe distance
Intense magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Skin irritation risks
Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, cease working with magnets and use protective gear.
Adults only
Adult use only. Tiny parts pose a choking risk, causing intestinal necrosis. Store away from children and animals.
Keep away from electronics
Note: rare earth magnets generate a field that interferes with precision electronics. Keep a safe distance from your phone, device, and GPS.
Crushing force
Danger of trauma: The attraction force is so immense that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.
Eye protection
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.
Heat sensitivity
Watch the temperature. Heating the magnet to high heat will ruin its magnetic structure and pulling force.
Health Danger
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
