Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- Their power is maintained, and after around 10 years it decreases only by ~1% (theoretically),
- They retain their magnetic properties even under strong external field,
- In other words, due to the glossy finish of silver, the element gains a professional look,
- Neodymium magnets achieve maximum magnetic induction on a their surface, which allows for strong attraction,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Due to the ability of accurate molding and adaptation to custom requirements, magnetic components can be created in a wide range of forms and dimensions, which expands the range of possible applications,
- Huge importance in modern technologies – they are used in hard drives, electric drive systems, diagnostic systems, also complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At 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.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- Due to limitations in realizing threads and complex forms in magnets, we recommend using a housing - magnetic mount.
- Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small elements of these products are able to complicate diagnosis medical after entering the body.
- Due to expensive raw materials, their price exceeds standard values,
Holding force characteristics
Maximum holding power of the magnet – what it depends on?
- using a base made of high-permeability steel, serving as a circuit closing element
- with a cross-section no less than 10 mm
- with an polished contact surface
- with zero gap (without paint)
- for force acting at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 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.
- Base massiveness – too thin plate does not accept the full field, causing part of the flux to be escaped to the other side.
- Chemical composition of the base – low-carbon steel gives the best results. Alloy steels lower magnetic properties and holding force.
- Surface finish – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
Operating temperature
Watch the temperature. Exposing the magnet to high heat will permanently weaken its magnetic structure and pulling force.
Fire risk
Dust created during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Safe operation
Use magnets consciously. Their immense force can shock even experienced users. Be vigilant and do not underestimate their force.
Electronic hazard
Do not bring magnets close to a wallet, laptop, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
Crushing force
Protect your hands. Two large magnets will snap together immediately with a force of massive weight, crushing everything in their path. Be careful!
Impact on smartphones
Navigation devices and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.
Material brittleness
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Sensitization to coating
A percentage of the population experience a hypersensitivity to nickel, which is the common plating for NdFeB magnets. Frequent touching may cause a rash. We recommend use safety gloves.
Pacemakers
Patients with a pacemaker have to keep an safe separation from magnets. The magnetic field can interfere with the functioning of the life-saving device.
Adults only
Strictly keep magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are tragic.
