Advantages as well as disadvantages of neodymium magnets.
Strengths
- They have stable power, and over around ten years their performance decreases symbolically – ~1% (according to theory),
- Neodymium magnets prove to be extremely resistant to magnetic field loss caused by external magnetic fields,
- Thanks to the elegant finish, the surface of Ni-Cu-Ni, gold-plated, or silver gives an aesthetic appearance,
- They feature high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Thanks to flexibility in shaping and the ability to customize to individual projects,
- Versatile presence in modern industrial fields – they serve a role in hard drives, brushless drives, diagnostic systems, as well as multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We suggest casing - magnetic mount, due to difficulties in creating nuts inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, small components of these magnets can complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum holding power of the magnet – what affects it?
- with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- whose thickness equals approx. 10 mm
- with an ground touching surface
- without the slightest clearance between the magnet and steel
- during detachment in a direction perpendicular to the plane
- at ambient temperature room level
Practical aspects of lifting capacity – factors
- Gap (between the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin plate does not close the flux, causing part of the flux to be wasted to the other side.
- Steel grade – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
- Smoothness – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, whereas under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate lowers the holding force.
Safe handling of NdFeB magnets
Avoid contact if allergic
Medical facts indicate that nickel (the usual finish) is a common allergen. For allergy sufferers, avoid direct skin contact or select coated magnets.
This is not a toy
These products are not toys. Accidental ingestion of several magnets may result in them attracting across intestines, which constitutes a direct threat to life and necessitates urgent medical intervention.
Threat to navigation
A strong magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Do not bring magnets close to a smartphone to prevent breaking the sensors.
Magnetic media
Intense magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Stay away of at least 10 cm.
Do not overheat magnets
Keep cool. NdFeB magnets are sensitive to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Risk of cracking
Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.
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.
Physical harm
Big blocks can smash fingers in a fraction of a second. Do not place your hand betwixt two attracting surfaces.
Medical implants
For implant holders: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or request help to handle the magnets.
Safe operation
Handle with care. Rare earth magnets attract from a long distance and connect with massive power, often quicker than you can move away.
