Pros as well as cons of neodymium magnets.
Advantages
- Their power is durable, and after approximately ten years it decreases only by ~1% (theoretically),
- Neodymium magnets remain exceptionally resistant to demagnetization caused by external magnetic fields,
- By using a shiny layer of nickel, the element presents an aesthetic look,
- The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Thanks to the ability of free shaping and adaptation to individualized needs, magnetic components can be modeled in a wide range of shapes and sizes, which amplifies use scope,
- Huge importance in future technologies – they are used in hard drives, electric drive systems, diagnostic systems, as well as complex engineering applications.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Limitations
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Limited possibility of producing nuts in the magnet and complex forms - recommended is casing - mounting mechanism.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small components of these devices are able to complicate diagnosis medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum holding power of the magnet – what affects it?
- on a base made of mild steel, perfectly concentrating the magnetic field
- possessing a massiveness of minimum 10 mm to avoid saturation
- characterized by even structure
- under conditions of ideal adhesion (metal-to-metal)
- under vertical force vector (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Gap (betwixt the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, rust or debris).
- Angle of force application – maximum parameter is available only during perpendicular pulling. The shear force of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Metal type – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was assessed by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Pinching danger
Mind your fingers. Two large magnets will snap together instantly with a force of massive weight, destroying anything in their path. Be careful!
Cards and drives
Intense magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Impact on smartphones
GPS units and smartphones are extremely susceptible to magnetism. Close proximity with a strong magnet can ruin the internal compass in your phone.
Medical implants
Patients with a ICD must maintain an absolute distance from magnets. The magnetic field can stop the operation of the life-saving device.
Fire warning
Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Do not underestimate power
Exercise caution. Rare earth magnets act from a distance and snap with huge force, often quicker than you can move away.
Choking Hazard
Only for adults. Small elements can be swallowed, leading to severe trauma. Keep out of reach of kids and pets.
Protective goggles
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets leads to them cracking into small pieces.
Thermal limits
Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Metal Allergy
Certain individuals experience a hypersensitivity to Ni, which is the common plating for neodymium magnets. Extended handling might lead to skin redness. We recommend wear protective gloves.
