Advantages as well as disadvantages of rare earth magnets.
Strengths
- They do not lose strength, even over around ten years – the decrease in strength is only ~1% (based on measurements),
- They maintain their magnetic properties even under close interference source,
- In other words, due to the smooth surface of silver, the element is aesthetically pleasing,
- Magnetic induction on the top side of the magnet turns out to be exceptional,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- In view of the possibility of precise forming and adaptation to individualized needs, magnetic components can be modeled in a variety of forms and dimensions, which makes them more universal,
- Wide application in future technologies – they are utilized in mass storage devices, electric drive systems, diagnostic systems, also modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating nuts and complicated shapes in magnets, we recommend using cover - magnetic mechanism.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these devices can be problematic in diagnostics medical in case of swallowing.
- Due to neodymium price, their price is relatively high,
Lifting parameters
Maximum holding power of the magnet – what affects it?
- on a base made of mild steel, perfectly concentrating the magnetic flux
- whose thickness equals approx. 10 mm
- with a surface cleaned and smooth
- with total lack of distance (no paint)
- for force applied at a right angle (in the magnet axis)
- in stable room temperature
Impact of factors on magnetic holding capacity in practice
- Clearance – the presence of any layer (rust, dirt, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of nominal force).
- Steel thickness – insufficiently thick steel does not accept the full field, causing part of the power to be escaped into the air.
- Metal type – not every steel attracts identically. High carbon content weaken the attraction effect.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal factor – hot environment reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
Protective goggles
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Physical harm
Pinching hazard: The pulling power is so great that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.
Handling guide
Before use, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Do not drill into magnets
Machining of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Heat warning
Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. This process is irreversible.
Do not give to children
Strictly keep magnets out of reach of children. Choking hazard is significant, and the consequences of magnets clamping inside the body are very dangerous.
Metal Allergy
It is widely known that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, prevent direct skin contact and opt for coated magnets.
Impact on smartphones
A strong magnetic field negatively affects the operation of magnetometers in smartphones and navigation systems. Keep magnets close to a smartphone to avoid breaking the sensors.
Medical implants
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
Protect data
Avoid bringing magnets close to a wallet, laptop, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
