Pros as well as cons of neodymium magnets.
Advantages
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (based on calculations),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- Thanks to the shimmering finish, the plating of nickel, gold-plated, or silver-plated gives an aesthetic appearance,
- The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures reaching 230°C and above...
- Thanks to modularity in constructing and the ability to modify to client solutions,
- Universal use in future technologies – they are utilized in magnetic memories, electromotive mechanisms, medical devices, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in small systems
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also improves 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 and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing threads and complicated forms in magnets, we recommend using casing - magnetic mount.
- Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these devices can complicate diagnosis medical in case of swallowing.
- Due to neodymium price, their price is relatively high,
Pull force analysis
Magnetic strength at its maximum – what affects it?
- on a base made of mild steel, perfectly concentrating the magnetic flux
- with a cross-section no less than 10 mm
- with a plane perfectly flat
- with zero gap (no paint)
- under vertical force direction (90-degree angle)
- at temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Distance (betwixt the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel type – mild steel gives the best results. Higher carbon content lower magnetic properties and holding force.
- Smoothness – full contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Operating temperature – neodymium magnets 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 the force acted perpendicularly, whereas under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
Permanent damage
Do not overheat. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Crushing risk
Large magnets can crush fingers instantly. Under no circumstances place your hand betwixt two strong magnets.
Nickel coating and allergies
It is widely known that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid touching magnets with bare hands or choose versions in plastic housing.
Handling guide
Exercise caution. Neodymium magnets act from a distance and snap with massive power, often faster than you can react.
Precision electronics
Be aware: neodymium magnets produce a field that confuses precision electronics. Maintain a safe distance from your mobile, device, and GPS.
Swallowing risk
Neodymium magnets are not intended for children. Accidental ingestion of multiple magnets may result in them attracting across intestines, which poses a severe health hazard and requires urgent medical intervention.
Magnet fragility
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Magnetic media
Avoid bringing magnets near a purse, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.
Danger to pacemakers
Patients with a pacemaker have to keep an safe separation from magnets. The magnetic field can disrupt the operation of the life-saving device.
Dust explosion hazard
Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
