Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- Neodymium magnets remain extremely resistant to demagnetization caused by external interference,
- By using a reflective layer of nickel, the element acquires an professional look,
- The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
- 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 individual forming and optimizing to concrete requirements,
- Huge importance in innovative solutions – they serve a role in magnetic memories, drive modules, diagnostic systems, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in miniature devices
Cons
- At strong impacts they can crack, therefore we recommend 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 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 while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We suggest a housing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these devices are able to complicate diagnosis medical when they are in the body.
- Due to expensive raw materials, their price exceeds standard values,
Holding force characteristics
Magnetic strength at its maximum – what contributes to it?
- on a plate made of structural steel, effectively closing the magnetic flux
- with a cross-section no less than 10 mm
- with a surface cleaned and smooth
- under conditions of gap-free contact (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- in temp. approx. 20°C
Magnet lifting force in use – key factors
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Load vector – maximum parameter is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick steel causes magnetic saturation, causing part of the power to be lost into the air.
- Chemical composition of the base – low-carbon steel gives the best results. Alloy steels decrease magnetic permeability and holding force.
- Plate texture – ground elements guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Precautions when working with NdFeB magnets
Fragile material
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets will cause them cracking into small pieces.
Nickel allergy
Certain individuals suffer from a sensitization to Ni, which is the common plating for neodymium magnets. Frequent touching might lead to a rash. We strongly advise use safety gloves.
Immense force
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Fire risk
Combustion risk: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.
Precision electronics
An intense magnetic field disrupts the operation of compasses in phones and GPS navigation. Keep magnets near a smartphone to prevent damaging the sensors.
Heat warning
Avoid heat. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Bone fractures
Large magnets can smash fingers instantly. Never put your hand betwixt two attracting surfaces.
Threat to electronics
Avoid bringing magnets close to a purse, computer, or screen. The magnetism can destroy these devices and wipe information from cards.
Warning for heart patients
For implant holders: Powerful magnets disrupt medical devices. Keep at least 30 cm distance or request help to handle the magnets.
This is not a toy
Always store magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are fatal.
