Advantages as well as disadvantages of rare earth magnets.
Pros
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- Magnets perfectly protect themselves against demagnetization caused by foreign field sources,
- In other words, due to the smooth layer of gold, the element becomes visually attractive,
- Magnetic induction on the working layer of the magnet remains impressive,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
- Possibility of individual shaping and adjusting to defined needs,
- Key role in electronics industry – they are commonly used in computer drives, electromotive mechanisms, precision medical tools, also industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets experience 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
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest a housing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical when they are in the body.
- Due to complex production process, their price exceeds standard values,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the application of a yoke made of special test steel, ensuring maximum field concentration
- with a cross-section of at least 10 mm
- with a surface perfectly flat
- without any insulating layer between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at temperature room level
Determinants of practical lifting force of a magnet
- Gap (betwixt the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to paint, corrosion or debris).
- Angle of force application – highest force is available only during perpendicular pulling. The shear force of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick plate does not close the flux, causing part of the power to be lost to the other side.
- Material composition – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
- Plate texture – ground elements ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity was measured using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
Warnings
Flammability
Drilling and cutting of NdFeB material carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Serious injuries
Mind your fingers. Two large magnets will snap together instantly with a force of massive weight, crushing anything in their path. Be careful!
Thermal limits
Regular neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Sensitization to coating
Some people suffer from a contact allergy to Ni, which is the typical protective layer for NdFeB magnets. Extended handling can result in skin redness. We suggest use safety gloves.
Respect the power
Use magnets with awareness. Their immense force can shock even professionals. Stay alert and respect their force.
Material brittleness
Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Medical implants
People with a ICD should maintain an safe separation from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Danger to the youngest
These products are not intended for children. Accidental ingestion of several magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and necessitates immediate surgery.
Magnetic interference
Note: neodymium magnets generate a field that interferes with precision electronics. Maintain a safe distance from your mobile, device, and GPS.
Data carriers
Equipment safety: Neodymium magnets can damage data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).
