Advantages and disadvantages of rare earth magnets.
Pros
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- They are noted for resistance to demagnetization induced by external magnetic fields,
- The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Magnets have huge magnetic induction on the outer side,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures approaching 230°C and above...
- Thanks to versatility in constructing and the capacity to customize to individual projects,
- Fundamental importance in modern technologies – they are utilized in magnetic memories, electromotive mechanisms, precision medical tools, and industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- Neodymium 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 very 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 secure oxidation as well as corrosion.
- Due to limitations in creating nuts and complicated forms in magnets, we recommend using cover - magnetic mount.
- Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products can be problematic in diagnostics medical when they are in the body.
- With large orders the cost of neodymium magnets is a challenge,
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- using a base made of high-permeability steel, acting as a magnetic yoke
- possessing a thickness of min. 10 mm to avoid saturation
- with a surface cleaned and smooth
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction vertical to the mounting surface
- at room temperature
Practical aspects of lifting capacity – factors
- Distance (between the magnet and the plate), since even a very small distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Material composition – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Temperature – temperature increase results in weakening of induction. Check the thermal limit for a given model.
Lifting capacity was assessed using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Powerful field
Exercise caution. Neodymium magnets act from a long distance and snap with massive power, often faster than you can react.
Do not give to children
NdFeB magnets are not toys. Eating multiple magnets may result in them attracting across intestines, which constitutes a direct threat to life and requires immediate surgery.
Crushing force
Watch your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Dust is flammable
Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Electronic devices
Avoid bringing magnets close to a purse, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.
Allergy Warning
It is widely known that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, avoid touching magnets with bare hands or select coated magnets.
Health Danger
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Operating temperature
Avoid heat. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
Keep away from electronics
An intense magnetic field disrupts the operation of compasses in smartphones and navigation systems. Keep magnets close to a smartphone to avoid breaking the sensors.
Material brittleness
Watch out for shards. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.
