Advantages as well as disadvantages of rare earth magnets.
Strengths
- They do not lose strength, even over around 10 years – the reduction in power is only ~1% (based on measurements),
- They possess excellent resistance to magnetism drop due to external fields,
- In other words, due to the aesthetic layer of nickel, the element becomes visually attractive,
- Neodymium magnets ensure maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- In view of the possibility of free forming and customization to unique projects, neodymium magnets can be created in a variety of forms and dimensions, which expands the range of possible applications,
- Fundamental importance in high-tech industry – they are utilized in computer drives, motor assemblies, advanced medical instruments, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in small systems
Cons
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their force 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
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of creating threads in the magnet and complicated forms - recommended is casing - magnetic holder.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which becomes key in the context of child health protection. It is also worth noting that small components of these devices are able to disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- using a plate made of mild steel, functioning as a circuit closing element
- with a thickness minimum 10 mm
- with an ground contact surface
- without the slightest clearance between the magnet and steel
- under vertical force direction (90-degree angle)
- at temperature room level
Key elements affecting lifting force
- Distance – existence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
- Steel thickness – too thin steel does not close the flux, causing part of the power to be lost to the other side.
- Material composition – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
- Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
- Temperature – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate lowers the holding force.
H&S for magnets
Magnets are brittle
NdFeB magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets leads to them cracking into shards.
Finger safety
Large magnets can crush fingers in a fraction of a second. Do not put your hand betwixt two attracting surfaces.
Maximum temperature
Regular neodymium magnets (N-type) lose power when the temperature surpasses 80°C. Damage is permanent.
Medical implants
Warning for patients: Powerful magnets affect medical devices. Keep at least 30 cm distance or request help to work with the magnets.
Electronic devices
Powerful magnetic fields can erase data on payment cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
Sensitization to coating
Certain individuals have a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Frequent touching can result in a rash. It is best to wear protective gloves.
Impact on smartphones
An intense magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Do not bring magnets close to a smartphone to avoid breaking the sensors.
This is not a toy
Absolutely keep magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are fatal.
Dust explosion hazard
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Caution required
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
