Pros and cons of Nd2Fe14B magnets.
Advantages
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
- Magnets perfectly protect themselves against demagnetization caused by external fields,
- In other words, due to the aesthetic layer of nickel, the element looks attractive,
- Neodymium magnets create maximum magnetic induction on a contact point, which allows for strong attraction,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
- Due to the possibility of free forming and adaptation to unique solutions, neodymium magnets can be produced in a wide range of forms and dimensions, which amplifies use scope,
- Significant place in electronics industry – they are used in hard drives, motor assemblies, precision medical tools, and other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases 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 and 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 magnets in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in creating nuts and complicated forms in magnets, we recommend using a housing - 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. Additionally, tiny parts of these magnets are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- using a sheet made of low-carbon steel, serving as a circuit closing element
- whose thickness is min. 10 mm
- with a plane cleaned and smooth
- under conditions of ideal adhesion (surface-to-surface)
- during pulling in a direction vertical to the plane
- at conditions approx. 20°C
Lifting capacity in real conditions – factors
- Clearance – the presence of any layer (rust, tape, air) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Chemical composition of the base – low-carbon steel attracts best. Alloy steels lower magnetic permeability and lifting capacity.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves force. Rough surfaces reduce efficiency.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was assessed by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet and the plate reduces the holding force.
H&S for magnets
Heat warning
Do not overheat. NdFeB magnets are susceptible to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).
GPS and phone interference
Navigation devices and mobile phones are highly susceptible to magnetic fields. Direct contact with a strong magnet can ruin the internal compass in your phone.
Material brittleness
Neodymium magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets will cause them breaking into shards.
Crushing force
Danger of trauma: The attraction force is so immense that it can cause hematomas, pinching, and broken bones. Use thick gloves.
Handling guide
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Allergic reactions
It is widely known that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, prevent touching magnets with bare hands and choose versions in plastic housing.
Warning for heart patients
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Safe distance
Do not bring magnets close to a purse, laptop, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
Do not give to children
These products are not intended for children. Accidental ingestion of a few magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and requires urgent medical intervention.
Combustion hazard
Drilling and cutting of neodymium magnets carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
