Strengths and weaknesses of rare earth magnets.
Pros
- They have unchanged lifting capacity, and over more than 10 years their performance decreases symbolically – ~1% (according to theory),
- They feature excellent resistance to magnetism drop due to external fields,
- In other words, due to the glossy surface of gold, the element gains a professional look,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures approaching 230°C and above...
- Due to the ability of flexible shaping and customization to custom requirements, magnetic components can be produced in a wide range of forms and dimensions, which increases their versatility,
- Versatile presence in advanced technology sectors – they find application in data components, drive modules, diagnostic systems, and complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At very strong impacts they can break, 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 power. Often, when the temperature exceeds 80°C, their strength 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
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Limited possibility of producing nuts in the magnet and complicated forms - recommended is cover - mounting mechanism.
- Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Furthermore, small elements of these products are able to complicate diagnosis medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum holding power of the magnet – what it depends on?
- on a plate made of mild steel, optimally conducting the magnetic field
- whose thickness is min. 10 mm
- characterized by even structure
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction vertical to the mounting surface
- at temperature room level
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Metal type – different alloys reacts the same. Alloy additives worsen the attraction effect.
- Surface condition – ground elements ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
- Thermal environment – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the lifting capacity.
Warnings
Do not overheat magnets
Regular neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. This process is irreversible.
Handling rules
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Keep away from children
Always keep magnets away from children. Ingestion danger is significant, and the effects of magnets clamping inside the body are fatal.
ICD Warning
Individuals with a ICD should keep an safe separation from magnets. The magnetism can disrupt the functioning of the life-saving device.
Machining danger
Fire warning: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.
Threat to electronics
Very strong magnetic fields can destroy records on credit cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.
Skin irritation risks
Studies show that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, prevent direct skin contact and choose versions in plastic housing.
Pinching danger
Large magnets can smash fingers in a fraction of a second. Never place your hand between two strong magnets.
Magnet fragility
NdFeB magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets will cause them shattering into shards.
Precision electronics
Navigation devices and smartphones are extremely susceptible to magnetism. Close proximity with a strong magnet can permanently damage the sensors in your phone.
