Advantages and disadvantages of rare earth magnets.
Benefits
- Their magnetic field is maintained, and after approximately 10 years it drops only by ~1% (theoretically),
- They are noted for resistance to demagnetization induced by external magnetic fields,
- The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnetic induction on the working layer of the magnet turns out to be strong,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures approaching 230°C and above...
- Possibility of precise creating as well as adjusting to precise requirements,
- Fundamental importance in electronics industry – they serve a role in HDD drives, electric motors, medical devices, and industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's 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 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 start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited possibility of producing nuts in the magnet and complicated forms - preferred is casing - mounting mechanism.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these products can complicate diagnosis medical after entering the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- using a sheet made of high-permeability steel, acting as a circuit closing element
- with a thickness of at least 10 mm
- with an polished touching surface
- under conditions of ideal adhesion (surface-to-surface)
- under axial force vector (90-degree angle)
- at temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Air gap (betwixt the magnet and the metal), since even a tiny distance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Material type – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined by applying a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
H&S for magnets
Fragile material
NdFeB magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets will cause them breaking into shards.
Combustion hazard
Machining of neodymium magnets carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Life threat
Individuals with a heart stimulator must keep an absolute distance from magnets. The magnetic field can disrupt the functioning of the life-saving device.
GPS and phone interference
Navigation devices and smartphones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Handling rules
Exercise caution. Rare earth magnets attract from a long distance and connect with massive power, often quicker than you can move away.
Hand protection
Risk of injury: The attraction force is so great that it can result in hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Cards and drives
Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, timepieces).
Sensitization to coating
A percentage of the population have a sensitization to nickel, which is the common plating for neodymium magnets. Prolonged contact might lead to a rash. We strongly advise wear protective gloves.
Product not for children
Strictly store magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are tragic.
Demagnetization risk
Avoid heat. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).
