Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- Their power is maintained, and after approximately 10 years it drops only by ~1% (according to research),
- They possess excellent resistance to weakening of magnetic properties as a result of opposing magnetic fields,
- Thanks to the reflective finish, the coating of Ni-Cu-Ni, gold-plated, or silver gives an visually attractive appearance,
- Magnetic induction on the working layer of the magnet is impressive,
- 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...
- Thanks to modularity in shaping and the capacity to adapt to complex applications,
- Versatile presence in future technologies – they are commonly used in computer drives, motor assemblies, medical devices, as well as multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. 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 power (a factor is the shape and 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
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of making nuts in the magnet and complex forms - recommended is cover - mounting mechanism.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical when they are in 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
Detachment force of the magnet in optimal conditions – what it depends on?
- using a base made of high-permeability steel, functioning as a circuit closing element
- possessing a thickness of at least 10 mm to avoid saturation
- with an ideally smooth touching surface
- without the slightest air gap between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at conditions approx. 20°C
Determinants of practical lifting force of a magnet
- Gap between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is reached only during perpendicular pulling. The shear force of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Steel grade – the best choice is high-permeability steel. Cast iron may generate lower lifting capacity.
- Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
- Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
Do not drill into magnets
Fire warning: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
Cards and drives
Intense magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.
Physical harm
Mind your fingers. Two powerful magnets will snap together immediately with a force of massive weight, crushing everything in their path. Be careful!
Operating temperature
Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and pulling force.
Keep away from children
Product intended for adults. Small elements can be swallowed, causing severe trauma. Store out of reach of kids and pets.
Do not underestimate power
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Nickel coating and allergies
It is widely known that nickel (the usual finish) is a common allergen. If you have an allergy, avoid touching magnets with bare hands and opt for versions in plastic housing.
Life threat
Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
GPS and phone interference
A strong magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Maintain magnets near a device to avoid damaging the sensors.
Material brittleness
Beware of splinters. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.
