Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- Their power is maintained, and after around ten years it drops only by ~1% (theoretically),
- They are extremely resistant to demagnetization induced by external magnetic fields,
- A magnet with a metallic silver surface looks better,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Due to the option of flexible shaping and adaptation to custom solutions, NdFeB magnets can be produced in a wide range of forms and dimensions, which amplifies use scope,
- Key role in advanced technology sectors – they are utilized in computer drives, drive modules, diagnostic systems, as well as industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- We suggest casing - magnetic mount, due to difficulties in producing threads inside the magnet and complex forms.
- Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small elements of these magnets can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Maximum holding power of the magnet – what contributes to it?
- on a block made of structural steel, perfectly concentrating the magnetic field
- whose thickness equals approx. 10 mm
- characterized by even structure
- under conditions of ideal adhesion (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- in neutral thermal conditions
Practical aspects of lifting capacity – factors
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Plate thickness – insufficiently thick plate causes magnetic saturation, causing part of the power to be escaped to the other side.
- Material composition – different alloys attracts identically. High carbon content weaken the attraction effect.
- Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
- Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet and the plate reduces the holding force.
Precautions when working with NdFeB magnets
Pinching danger
Protect your hands. Two powerful magnets will join immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Power loss in heat
Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Pacemakers
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Beware of splinters
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets leads to them cracking into shards.
Powerful field
Before starting, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Dust is flammable
Powder produced during machining of magnets is combustible. Do not drill into magnets unless you are an expert.
Sensitization to coating
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation occurs, immediately stop handling magnets and wear gloves.
Phone sensors
An intense magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Do not bring magnets near a smartphone to avoid breaking the sensors.
Keep away from computers
Equipment safety: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, medical aids, timepieces).
No play value
Strictly store magnets out of reach of children. Ingestion danger is significant, and the effects of magnets clamping inside the body are fatal.
