Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They have constant strength, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
- They possess excellent resistance to magnetism drop due to opposing magnetic fields,
- Thanks to the shimmering finish, the plating of Ni-Cu-Ni, gold-plated, or silver gives an elegant appearance,
- They feature high magnetic induction at the operating surface, making them more effective,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Due to the option of free molding and adaptation to individualized solutions, NdFeB magnets can be manufactured in a broad palette of geometric configurations, which amplifies use scope,
- Fundamental importance in modern technologies – they are used in mass storage devices, electric motors, advanced medical instruments, and technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power 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 usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in producing threads and complex forms in magnets, we propose using casing - magnetic mount.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
- With mass production the cost of neodymium magnets is economically unviable,
Lifting parameters
Detachment force of the magnet in optimal conditions – what it depends on?
- using a base made of high-permeability steel, functioning as a magnetic yoke
- with a thickness minimum 10 mm
- with a surface perfectly flat
- with direct contact (no coatings)
- under vertical force direction (90-degree angle)
- at room temperature
What influences lifting capacity in practice
- Distance – the presence of foreign body (paint, tape, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material type – the best choice is pure iron steel. Cast iron may attract less.
- Surface structure – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
Warnings
Operating temperature
Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. Damage is permanent.
Precision electronics
An intense magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Do not bring magnets close to a smartphone to avoid damaging the sensors.
Serious injuries
Watch your fingers. Two large magnets will join instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!
Conscious usage
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Threat to electronics
Intense magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.
ICD Warning
Medical warning: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
Shattering risk
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Keep away from children
Strictly keep magnets out of reach of children. Choking hazard is high, and the effects of magnets connecting inside the body are tragic.
Warning for allergy sufferers
Some people suffer from a sensitization to nickel, which is the typical protective layer for neodymium magnets. Frequent touching might lead to an allergic reaction. We suggest use safety gloves.
Do not drill into magnets
Drilling and cutting of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
