Pros and cons of neodymium magnets.
Benefits
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (according to literature),
- Neodymium magnets remain extremely resistant to magnetic field loss caused by external field sources,
- A magnet with a metallic nickel surface is more attractive,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
- Thanks to flexibility in designing and the ability to modify to individual projects,
- Huge importance in modern industrial fields – they are utilized in mass storage devices, drive modules, diagnostic systems, and modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- At strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. 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
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Limited ability of making nuts in the magnet and complex forms - recommended is casing - mounting mechanism.
- Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small elements of these devices are able to be problematic in diagnostics medical when they are in the body.
- Due to complex production process, their price is relatively high,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- using a plate made of low-carbon steel, acting as a ideal flux conductor
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- characterized by smoothness
- without any clearance between the magnet and steel
- during detachment in a direction perpendicular to the mounting surface
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Base massiveness – too thin steel causes magnetic saturation, causing part of the power to be wasted to the other side.
- Plate material – mild steel gives the best results. Alloy steels lower magnetic properties and holding force.
- Surface structure – the more even the surface, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
Safety rules for work with neodymium magnets
Warning for allergy sufferers
Studies show that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands or select coated magnets.
Handling guide
Handle with care. Neodymium magnets attract from a distance and snap with huge force, often faster than you can react.
Magnets are brittle
NdFeB magnets are ceramic materials, meaning they are fragile like glass. Impact of two magnets leads to them shattering into small pieces.
Danger to the youngest
Product intended for adults. Small elements can be swallowed, causing severe trauma. Store away from kids and pets.
Fire risk
Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Impact on smartphones
Navigation devices and smartphones are highly susceptible to magnetic fields. Close proximity with a strong magnet can permanently damage the internal compass in your phone.
Medical implants
Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
Serious injuries
Watch your fingers. Two large magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!
Cards and drives
Equipment safety: Strong magnets can damage data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).
Demagnetization risk
Do not overheat. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, look for HT versions (H, SH, UH).
