Pros as well as cons of rare earth magnets.
Pros
- They have constant strength, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
- They retain their magnetic properties even under strong external field,
- The use of an refined finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- The surface of neodymium magnets generates a powerful magnetic field – this is one of their assets,
- 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...
- Thanks to versatility in designing and the ability to modify to client solutions,
- Huge importance in future technologies – they are used in computer drives, brushless drives, advanced medical instruments, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in small systems
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength 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. 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 producing threads and complex forms in magnets, we propose using a housing - magnetic holder.
- Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Additionally, tiny parts of these products can complicate diagnosis medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Holding force characteristics
Maximum magnetic pulling force – what contributes to it?
- with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
- possessing a massiveness of minimum 10 mm to avoid saturation
- with an polished touching surface
- with direct contact (no coatings)
- under axial force vector (90-degree angle)
- at room temperature
What influences lifting capacity in practice
- Distance – the presence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Steel type – mild steel attracts best. Alloy admixtures lower magnetic permeability and lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
- Thermal factor – hot environment weakens pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet and the plate decreases the holding force.
H&S for magnets
Do not underestimate power
Handle magnets with awareness. Their immense force can surprise even experienced users. Stay alert and do not underestimate their power.
Do not give to children
Neodymium magnets are not intended for children. Accidental ingestion of a few magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and requires urgent medical intervention.
Keep away from computers
Very strong magnetic fields can destroy records on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.
Permanent damage
Monitor thermal conditions. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.
GPS Danger
A powerful magnetic field disrupts the functioning of compasses in smartphones and navigation systems. Maintain magnets near a smartphone to prevent breaking the sensors.
Serious injuries
Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Danger to pacemakers
People with a heart stimulator should keep an safe separation from magnets. The magnetic field can stop the operation of the implant.
Beware of splinters
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets will cause them shattering into small pieces.
Nickel allergy
A percentage of the population have a hypersensitivity to nickel, which is the common plating for neodymium magnets. Frequent touching might lead to a rash. It is best to use safety gloves.
Combustion hazard
Dust created during machining of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
