Advantages as well as disadvantages of neodymium magnets.
Pros
- Their magnetic field is durable, and after approximately ten years it decreases only by ~1% (according to research),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- In other words, due to the smooth finish of gold, the element gains visual value,
- Magnetic induction on the working layer of the magnet remains strong,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of accurate modeling as well as optimizing to defined requirements,
- Versatile presence in electronics industry – they find application in HDD drives, electric drive systems, advanced medical instruments, as well as industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited possibility of creating nuts in the magnet and complex shapes - preferred is casing - mounting mechanism.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these devices are able to be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum lifting force for a neodymium magnet – what it depends on?
- with the use of a sheet made of special test steel, guaranteeing maximum field concentration
- whose transverse dimension reaches at least 10 mm
- characterized by smoothness
- under conditions of ideal adhesion (metal-to-metal)
- under perpendicular application of breakaway force (90-degree angle)
- at conditions approx. 20°C
Magnet lifting force in use – key factors
- Clearance – the presence of foreign body (paint, dirt, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
- Material type – the best choice is high-permeability steel. Hardened steels may attract less.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
H&S for magnets
Hand protection
Large magnets can crush fingers instantly. Never put your hand between two attracting surfaces.
Do not drill into magnets
Mechanical processing of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Magnets are brittle
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Permanent damage
Watch the temperature. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
Danger to pacemakers
People with a pacemaker must maintain an large gap from magnets. The magnetism can interfere with the functioning of the implant.
Handling guide
Exercise caution. Neodymium magnets attract from a long distance and snap with massive power, often faster than you can react.
Allergy Warning
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation appears, immediately stop working with magnets and use protective gear.
Protect data
Intense magnetic fields can erase data on payment cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Magnetic interference
Note: neodymium magnets generate a field that disrupts sensitive sensors. Maintain a separation from your phone, tablet, and navigation systems.
Swallowing risk
NdFeB magnets are not toys. Accidental ingestion of a few magnets can lead to them attracting across intestines, which constitutes a direct threat to life and necessitates immediate surgery.
