Advantages and disadvantages of rare earth magnets.
Strengths
- They have constant strength, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
- Neodymium magnets prove to be remarkably resistant to loss of magnetic properties caused by external magnetic fields,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- They feature high magnetic induction at the operating surface, which affects their effectiveness,
- 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...
- Due to the ability of free molding and adaptation to specialized solutions, neodymium magnets can be produced in a wide range of forms and dimensions, which expands the range of possible applications,
- Huge importance in modern industrial fields – they are commonly used in magnetic memories, electric drive systems, medical devices, as well as other advanced devices.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Limitations
- At strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. 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 usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited possibility of creating threads in the magnet and complicated shapes - recommended is cover - magnet mounting.
- Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices can complicate diagnosis medical after entering the body.
- Due to complex production process, their price is higher than average,
Pull force analysis
Best holding force of the magnet in ideal parameters – what affects it?
- with the application of a yoke made of special test steel, ensuring maximum field concentration
- possessing a thickness of min. 10 mm to avoid saturation
- with a plane perfectly flat
- under conditions of ideal adhesion (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 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.
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Material type – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
- Surface structure – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Temperature – temperature increase causes a temporary drop 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 a perpendicular force was applied, whereas under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate decreases the lifting capacity.
Safety rules for work with NdFeB magnets
Keep away from computers
Powerful magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Danger to the youngest
Only for adults. Tiny parts can be swallowed, causing serious injuries. Store away from kids and pets.
Respect the power
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Implant safety
Warning for patients: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or request help to handle the magnets.
Bone fractures
Danger of trauma: The pulling power is so immense that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Eye protection
Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Skin irritation risks
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, immediately stop working with magnets and use protective gear.
Fire risk
Powder generated during grinding of magnets is combustible. Do not drill into magnets unless you are an expert.
Permanent damage
Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
Keep away from electronics
Be aware: neodymium magnets generate a field that interferes with precision electronics. Keep a safe distance from your mobile, device, and GPS.
