Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They do not lose strength, even during nearly 10 years – the drop in strength is only ~1% (theoretically),
- Neodymium magnets remain highly resistant to loss of magnetic properties caused by magnetic disturbances,
- By using a shiny coating of gold, the element presents an elegant look,
- Magnetic induction on the working layer of the magnet is very high,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Due to the potential of precise forming and customization to unique projects, NdFeB magnets can be produced in a wide range of shapes and sizes, which increases their versatility,
- Versatile presence in electronics industry – they are utilized in HDD drives, brushless drives, advanced medical instruments, and industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Cons
- At very strong impacts they can break, therefore we recommend placing them in steel cases. 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 power. Often, when the temperature exceeds 80°C, their power 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 and corrosion.
- Limited possibility of making nuts in the magnet and complex shapes - recommended is cover - magnet mounting.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these devices can disrupt the diagnostic process medical in case of swallowing.
- With mass production the cost of neodymium magnets is economically unviable,
Lifting parameters
Maximum holding power of the magnet – what it depends on?
- with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- with a thickness of at least 10 mm
- with an ground touching surface
- with total lack of distance (without paint)
- for force acting at a right angle (pull-off, not shear)
- at standard ambient temperature
Key elements affecting lifting force
- Space between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Base massiveness – insufficiently thick sheet does not close the flux, causing part of the flux to be wasted to the other side.
- Metal type – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
- Surface finish – full contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was determined by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet and the plate decreases the lifting capacity.
Warnings
Nickel coating and allergies
It is widely known that nickel (standard magnet coating) is a common allergen. If you have an allergy, refrain from direct skin contact and opt for encased magnets.
Machining danger
Dust produced during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Respect the power
Exercise caution. Rare earth magnets act from a long distance and snap with huge force, often quicker than you can move away.
Bodily injuries
Risk of injury: The attraction force is so immense that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
Keep away from children
Only for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Store away from children and animals.
Electronic hazard
Do not bring magnets close to a wallet, computer, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
GPS Danger
Note: neodymium magnets generate a field that confuses sensitive sensors. Keep a safe distance from your phone, tablet, and GPS.
Health Danger
Patients with a ICD must maintain an safe separation from magnets. The magnetic field can stop the operation of the implant.
Magnets are brittle
Neodymium magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets will cause them breaking into shards.
Permanent damage
Avoid heat. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
