Advantages and disadvantages of rare earth magnets.
Pros
- They retain full power for around 10 years – the drop is just ~1% (according to analyses),
- Magnets perfectly protect themselves against loss of magnetization caused by ambient magnetic noise,
- A magnet with a shiny nickel surface looks better,
- The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
- Possibility of custom modeling and modifying to concrete conditions,
- Fundamental importance in electronics industry – they are commonly used in magnetic memories, motor assemblies, advanced medical instruments, and other advanced devices.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Disadvantages
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in force. 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 start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of producing nuts in the magnet and complex forms - recommended is casing - magnetic holder.
- Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Furthermore, tiny parts of these magnets can disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Highest magnetic holding force – what it depends on?
- on a plate made of structural steel, perfectly concentrating the magnetic field
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with a plane perfectly flat
- under conditions of gap-free contact (metal-to-metal)
- during pulling in a direction vertical to the plane
- in temp. approx. 20°C
Determinants of practical lifting force of a magnet
- Gap (between the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Plate material – mild steel gives the best results. Alloy steels decrease magnetic permeability and holding force.
- Surface finish – ideal contact is possible only on polished steel. Rough texture create air cushions, reducing force.
- Temperature – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the holding force.
H&S for magnets
Life threat
Life threat: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
No play value
Only for adults. Small elements pose a choking risk, causing severe trauma. Keep away from children and animals.
Crushing risk
Watch your fingers. Two large magnets will join instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Phone sensors
Remember: rare earth magnets generate a field that interferes with sensitive sensors. Maintain a separation from your phone, tablet, and GPS.
Cards and drives
Data protection: Strong magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, timepieces).
Magnet fragility
Neodymium magnets are sintered ceramics, meaning they are very brittle. Collision of two magnets leads to them shattering into small pieces.
Handling rules
Handle magnets with awareness. Their huge power can shock even experienced users. Be vigilant and do not underestimate their force.
Nickel allergy
Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction happens, immediately stop working with magnets and wear gloves.
Power loss in heat
Keep cool. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
Flammability
Powder generated during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
