Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- Their power is durable, and after around ten years it decreases only by ~1% (according to research),
- They are resistant to demagnetization induced by external disturbances,
- In other words, due to the reflective finish of nickel, the element gains a professional look,
- Magnetic induction on the top side of the magnet turns out to be strong,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Considering the option of flexible forming and customization to specialized needs, neodymium magnets can be manufactured in a variety of geometric configurations, which increases their versatility,
- Huge importance in advanced technology sectors – they are used in mass storage devices, motor assemblies, advanced medical instruments, also modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- Due to limitations in realizing nuts and complicated forms in magnets, we propose using cover - magnetic holder.
- Health risk to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child safety. Additionally, small elements of these devices can disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Highest magnetic holding force – what it depends on?
- on a base made of structural steel, effectively closing the magnetic flux
- with a thickness minimum 10 mm
- characterized by smoothness
- under conditions of ideal adhesion (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- at conditions approx. 20°C
Practical aspects of lifting capacity – factors
- Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Plate material – low-carbon steel attracts best. Alloy admixtures lower magnetic properties and holding force.
- Smoothness – ideal contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
Safety rules for work with neodymium magnets
Skin irritation risks
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, immediately stop handling magnets and wear gloves.
Risk of cracking
Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Keep away from electronics
A powerful magnetic field negatively affects the operation of magnetometers in smartphones and navigation systems. Keep magnets close to a smartphone to prevent damaging the sensors.
Medical interference
Patients with a pacemaker have to maintain an safe separation from magnets. The magnetism can interfere with the functioning of the life-saving device.
Flammability
Powder created during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Hand protection
Protect your hands. Two powerful magnets will join instantly with a force of massive weight, crushing everything in their path. Be careful!
Keep away from computers
Equipment safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, medical aids, mechanical watches).
Do not give to children
NdFeB magnets are not intended for children. Eating a few magnets may result in them attracting across intestines, which constitutes a direct threat to life and necessitates urgent medical intervention.
Safe operation
Handle with care. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can react.
Permanent damage
Keep cool. Neodymium magnets are sensitive to temperature. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
