Pros and cons of Nd2Fe14B magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They do not lose their magnetic properties even under external field action,
- A magnet with a metallic silver surface has an effective appearance,
- Magnets possess exceptionally strong magnetic induction on the outer side,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of individual creating and modifying to defined conditions,
- Versatile presence in high-tech industry – they find application in magnetic memories, drive modules, diagnostic systems, and complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength 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.
- We suggest casing - magnetic holder, due to difficulties in creating threads inside the magnet and complicated forms.
- Potential hazard resulting from small fragments 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 magnets can be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets can be a barrier,
Lifting parameters
Best holding force of the magnet in ideal parameters – what affects it?
- on a plate made of structural steel, optimally conducting the magnetic flux
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- characterized by smoothness
- without any insulating layer between the magnet and steel
- under vertical force vector (90-degree angle)
- at temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Distance (between the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, rust or debris).
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material composition – different alloys reacts the same. High carbon content weaken the attraction effect.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate decreases the holding force.
Safe handling of NdFeB magnets
Metal Allergy
It is widely known that the nickel plating (the usual finish) is a common allergen. If you have an allergy, refrain from touching magnets with bare hands and choose encased magnets.
Protective goggles
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Power loss in heat
Keep cool. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Product not for children
Absolutely store magnets away from children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are fatal.
Life threat
Warning for patients: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or request help to handle the magnets.
Magnetic interference
A powerful magnetic field disrupts the functioning of compasses in phones and navigation systems. Keep magnets close to a device to avoid breaking the sensors.
Fire warning
Dust produced during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Immense force
Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Physical harm
Large magnets can break fingers in a fraction of a second. Under no circumstances put your hand between two strong magnets.
Data carriers
Avoid bringing magnets close to a purse, laptop, or screen. The magnetism can permanently damage these devices and erase data from cards.
