Pros and cons of Nd2Fe14B magnets.
Strengths
- They do not lose power, even after nearly ten years – the decrease in lifting capacity is only ~1% (theoretically),
- They maintain their magnetic properties even under external field action,
- In other words, due to the aesthetic surface of gold, the element becomes visually attractive,
- Magnets are characterized by excellent magnetic induction on the active area,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to freedom in designing and the ability to customize to individual projects,
- Huge importance in future technologies – they are commonly used in mass storage devices, motor assemblies, medical devices, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in miniature devices
Disadvantages
- At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of producing threads in the magnet and complex forms - recommended is a housing - magnet mounting.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. Furthermore, small components of these magnets can complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what it depends on?
- using a plate made of mild steel, acting as a circuit closing element
- with a cross-section no less than 10 mm
- with an polished contact surface
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction vertical to the plane
- in stable room temperature
Key elements affecting lifting force
- Distance (betwixt the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, corrosion or debris).
- Angle of force application – maximum parameter is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be escaped into the air.
- Material type – the best choice is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Smoothness – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was assessed with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.
H&S for magnets
Permanent damage
Watch the temperature. Exposing the magnet to high heat will ruin its properties and strength.
Do not give to children
Product intended for adults. Tiny parts pose a choking risk, leading to serious injuries. Keep out of reach of kids and pets.
Implant safety
Warning for patients: Powerful magnets affect medical devices. Maintain at least 30 cm distance or request help to handle the magnets.
Allergy Warning
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, cease handling magnets and wear gloves.
Threat to navigation
A powerful magnetic field disrupts the functioning of magnetometers in phones and GPS navigation. Keep magnets close to a smartphone to avoid damaging the sensors.
Dust is flammable
Drilling and cutting of NdFeB material carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Immense force
Handle with care. Rare earth magnets act from a long distance and connect with huge force, often quicker than you can react.
Risk of cracking
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Safe distance
Very strong magnetic fields can destroy records on payment cards, hard drives, and storage devices. Stay away of at least 10 cm.
Hand protection
Pinching hazard: The attraction force is so great that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
