Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- Their strength is durable, and after around 10 years it drops only by ~1% (according to research),
- They have excellent resistance to weakening of magnetic properties as a result of opposing magnetic fields,
- In other words, due to the aesthetic layer of gold, the element gains visual value,
- They show high magnetic induction at the operating surface, making them more effective,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures approaching 230°C and above...
- Thanks to modularity in constructing and the capacity to modify to specific needs,
- Huge importance in innovative solutions – they are utilized in HDD drives, brushless drives, precision medical tools, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in compact constructions
Limitations
- At strong impacts they can crack, therefore we advise placing them in strong housings. 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, as well as 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 corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend cover - magnetic mount, due to difficulties in creating threads inside the magnet and complex forms.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these products are able to complicate diagnosis 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
Detachment force of the magnet in optimal conditions – what affects it?
- with the contact of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- possessing a thickness of at least 10 mm to ensure full flux closure
- with an ideally smooth contact surface
- with direct contact (without paint)
- for force acting at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Clearance – existence of any layer (rust, tape, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- 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.
- Steel thickness – too thin plate causes magnetic saturation, causing part of the flux to be lost into the air.
- Metal type – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
- Surface structure – the more even the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Thermal environment – temperature increase results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity was assessed using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate lowers the holding force.
Precautions when working with NdFeB magnets
Choking Hazard
These products are not intended for children. Accidental ingestion of multiple magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and necessitates urgent medical intervention.
Skin irritation risks
It is widely known that the nickel plating (standard magnet coating) is a strong allergen. For allergy sufferers, prevent touching magnets with bare hands and choose coated magnets.
Machining danger
Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.
Compass and GPS
A strong magnetic field disrupts the functioning of compasses in smartphones and GPS navigation. Keep magnets close to a smartphone to prevent breaking the sensors.
Medical implants
For implant holders: Strong magnetic fields affect electronics. Maintain at least 30 cm distance or request help to work with the magnets.
Magnets are brittle
Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.
Thermal limits
Regular neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. The loss of strength is permanent.
Bone fractures
Risk of injury: The pulling power is so immense that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Caution required
Exercise caution. Neodymium magnets act from a distance and connect with huge force, often faster than you can react.
Threat to electronics
Device Safety: Neodymium magnets can damage payment cards and sensitive devices (heart implants, medical aids, timepieces).
