Strengths as well as weaknesses of rare earth magnets.
Pros
- They retain full power for around 10 years – the loss is just ~1% (in theory),
- They possess excellent resistance to magnetic field loss when exposed to external fields,
- Thanks to the glossy finish, the layer of nickel, gold, or silver-plated gives an clean appearance,
- Neodymium magnets achieve maximum magnetic induction on a their surface, which ensures high operational effectiveness,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- In view of the possibility of accurate forming and adaptation to unique projects, NdFeB magnets can be produced in a wide range of forms and dimensions, which makes them more universal,
- Versatile presence in future technologies – they find application in magnetic memories, motor assemblies, precision medical tools, and multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Due to limitations in creating nuts and complicated shapes in magnets, we propose using a housing - magnetic mechanism.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. Additionally, small elements of these products are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Highest magnetic holding force – what affects it?
- on a block made of mild steel, effectively closing the magnetic field
- possessing a thickness of min. 10 mm to ensure full flux closure
- characterized by smoothness
- under conditions of ideal adhesion (surface-to-surface)
- during pulling in a direction vertical to the plane
- at ambient temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Space between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Angle of force application – highest force is available only during perpendicular pulling. The shear force of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – too thin plate does not accept the full field, causing part of the flux to be lost into the air.
- Chemical composition of the base – low-carbon steel attracts best. Higher carbon content reduce magnetic permeability and holding force.
- Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Thermal environment – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the holding force.
Safe handling of neodymium magnets
GPS Danger
GPS units and smartphones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can permanently damage the sensors in your phone.
Powerful field
Be careful. Rare earth magnets attract from a distance and connect with massive power, often faster than you can react.
Fire warning
Mechanical processing of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Operating temperature
Watch the temperature. Heating the magnet to high heat will permanently weaken its properties and pulling force.
Electronic hazard
Intense magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Magnet fragility
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets will cause them cracking into small pieces.
Life threat
People with a ICD should maintain an large gap from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Bone fractures
Danger of trauma: The pulling power is so great that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
Nickel coating and allergies
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness occurs, cease working with magnets and use protective gear.
Swallowing risk
Product intended for adults. Tiny parts can be swallowed, causing severe trauma. Keep away from children and animals.
