Advantages as well as disadvantages of Nd2Fe14B magnets.
Benefits
- They retain attractive force for nearly ten years – the loss is just ~1% (in theory),
- They maintain their magnetic properties even under external field action,
- In other words, due to the smooth finish of silver, the element gains visual value,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
- 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 flexibility in forming and the ability to customize to client solutions,
- Fundamental importance in modern technologies – they are used in mass storage devices, electromotive mechanisms, advanced medical instruments, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in small systems
Disadvantages
- At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in realizing threads and complicated shapes in magnets, we propose using a housing - magnetic holder.
- Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- Due to expensive raw materials, their price exceeds standard values,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the contact of a sheet made of special test steel, ensuring full magnetic saturation
- whose transverse dimension equals approx. 10 mm
- with a plane perfectly flat
- without any insulating layer between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at room temperature
Lifting capacity in real conditions – factors
- Air gap (betwixt the magnet and the metal), as even a very small clearance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Steel thickness – too thin steel does not close the flux, causing part of the flux to be lost into the air.
- Chemical composition of the base – low-carbon steel attracts best. Higher carbon content reduce magnetic properties and lifting capacity.
- Surface condition – ground elements ensure maximum contact, which improves force. Uneven metal weaken the grip.
- 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).
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate decreases the holding force.
Safety rules for work with neodymium magnets
Magnetic media
Very strong magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Keep away from children
Only for adults. Tiny parts pose a choking risk, causing serious injuries. Store out of reach of kids and pets.
ICD Warning
People with a heart stimulator have to maintain an safe separation from magnets. The magnetism can interfere with the functioning of the implant.
Protective goggles
NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Impact of two magnets will cause them breaking into shards.
Allergic reactions
It is widely known that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, prevent touching magnets with bare hands and opt for versions in plastic housing.
GPS Danger
GPS units and mobile phones are extremely sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Hand protection
Pinching hazard: The attraction force is so immense that it can cause blood blisters, crushing, and broken bones. Use thick gloves.
Heat warning
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. Damage is permanent.
Dust is flammable
Drilling and cutting of neodymium magnets carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Immense force
Use magnets consciously. Their huge power can surprise even experienced users. Be vigilant and do not underestimate their force.
