Advantages and disadvantages of rare earth magnets.
Benefits
- They retain full power for nearly 10 years – the loss is just ~1% (based on simulations),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- In other words, due to the glossy layer of gold, the element is aesthetically pleasing,
- Magnets possess impressive magnetic induction on the working surface,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
- Possibility of detailed machining and adapting to individual conditions,
- Huge importance in modern technologies – they are utilized in data components, brushless drives, advanced medical instruments, as well as technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Disadvantages
- At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- We recommend casing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets can disrupt the diagnostic process medical after entering the body.
- With large orders the cost of neodymium magnets is a challenge,
Pull force analysis
Maximum magnetic pulling force – what it depends on?
- with the contact of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with a plane cleaned and smooth
- under conditions of no distance (surface-to-surface)
- during pulling in a direction vertical to the mounting surface
- at conditions approx. 20°C
Key elements affecting lifting force
- Distance – existence of foreign body (paint, tape, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Direction of force – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually many times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick plate causes magnetic saturation, causing part of the power to be escaped into the air.
- Steel grade – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
- Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
- Thermal factor – hot environment reduces pulling force. 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 holding force is lower. Moreover, even a slight gap between the magnet and the plate reduces the lifting capacity.
Warnings
Precision electronics
An intense magnetic field negatively affects the operation of compasses in smartphones and navigation systems. Maintain magnets near a smartphone to avoid damaging the sensors.
Life threat
Individuals with a heart stimulator have to maintain an absolute distance from magnets. The magnetic field can interfere with the functioning of the implant.
Avoid contact if allergic
A percentage of the population suffer from a sensitization to nickel, which is the typical protective layer for neodymium magnets. Frequent touching can result in dermatitis. We suggest wear protective gloves.
Material brittleness
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Flammability
Powder produced during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Heat sensitivity
Keep cool. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Hand protection
Pinching hazard: The pulling power is so great that it can result in blood blisters, crushing, and broken bones. Use thick gloves.
Danger to the youngest
Strictly keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are life-threatening.
Threat to electronics
Intense magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
Caution required
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
