Advantages and disadvantages of neodymium magnets.
Strengths
- They retain magnetic properties for around 10 years – the drop is just ~1% (according to analyses),
- Neodymium magnets remain extremely resistant to loss of magnetic properties caused by external magnetic fields,
- A magnet with a metallic silver surface is more attractive,
- They feature high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Possibility of accurate modeling and adjusting to concrete conditions,
- Wide application in advanced technology sectors – they serve a role in magnetic memories, brushless drives, diagnostic systems, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in small systems
Weaknesses
- At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. 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
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We recommend cover - magnetic mechanism, due to difficulties in creating threads inside the magnet and complex shapes.
- Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting force for a neodymium magnet – what contributes to it?
- with the use of a yoke made of special test steel, guaranteeing full magnetic saturation
- whose thickness equals approx. 10 mm
- characterized by even structure
- under conditions of no distance (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at room temperature
Impact of factors on magnetic holding capacity in practice
- Clearance – existence of foreign body (rust, tape, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Steel thickness – too thin sheet does not accept the full field, causing part of the power to be wasted to the other side.
- Steel type – mild steel attracts best. Alloy steels decrease magnetic permeability and holding force.
- Base smoothness – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently damage the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate decreases the holding force.
Warnings
Handling guide
Handle with care. Neodymium magnets act from a distance and snap with massive power, often faster than you can react.
Adults only
Strictly keep magnets out of reach of children. Ingestion danger is significant, and the effects of magnets connecting inside the body are fatal.
Crushing force
Big blocks can smash fingers instantly. Under no circumstances put your hand betwixt two strong magnets.
Flammability
Combustion risk: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.
Thermal limits
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. This process is irreversible.
Electronic devices
Powerful magnetic fields can destroy records on credit cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
Medical implants
Patients with a pacemaker must maintain an large gap from magnets. The magnetism can interfere with the operation of the life-saving device.
Keep away from electronics
Navigation devices and mobile phones are highly sensitive to magnetic fields. Direct contact with a strong magnet can permanently damage the sensors in your phone.
Nickel coating and allergies
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If redness happens, immediately stop working with magnets and wear gloves.
Risk of cracking
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
