Pros as well as cons of rare earth magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- A magnet with a shiny gold surface looks better,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the ability of accurate molding and customization to specialized projects, magnetic components can be modeled in a variety of shapes and sizes, which expands the range of possible applications,
- Significant place in modern technologies – they are used in magnetic memories, drive modules, precision medical tools, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in small systems
Limitations
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets lose strength 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 rust. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We recommend casing - magnetic holder, due to difficulties in creating nuts inside the magnet and complex forms.
- Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical after entering the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what affects it?
- with the contact of a yoke made of special test steel, ensuring full magnetic saturation
- whose transverse dimension equals approx. 10 mm
- with a surface free of scratches
- under conditions of gap-free contact (metal-to-metal)
- under perpendicular force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Gap (betwixt the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to paint, rust or dirt).
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Smoothness – ideal contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Precautions when working with NdFeB magnets
Bodily injuries
Mind your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Product not for children
Neodymium magnets are not suitable for play. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and necessitates urgent medical intervention.
Eye protection
Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Electronic hazard
Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).
Immense force
Handle with care. Rare earth magnets act from a distance and snap with huge force, often faster than you can move away.
Operating temperature
Do not overheat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, ask us about HT versions (H, SH, UH).
Medical interference
Medical warning: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Metal Allergy
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, immediately stop working with magnets and use protective gear.
Compass and GPS
An intense magnetic field interferes with the operation of compasses in phones and GPS navigation. Keep magnets close to a device to avoid damaging the sensors.
Dust is flammable
Dust created during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
