Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- Their magnetic field is durable, and after approximately 10 years it decreases only by ~1% (according to research),
- Magnets effectively resist against demagnetization caused by external fields,
- Thanks to the reflective finish, the surface of Ni-Cu-Ni, gold-plated, or silver gives an aesthetic appearance,
- Magnets have very high magnetic induction on the surface,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Thanks to freedom in constructing and the capacity to adapt to specific needs,
- Universal use in innovative solutions – they find application in hard drives, electric motors, diagnostic systems, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in compact constructions
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in creating nuts and complex forms in magnets, we propose using cover - magnetic mount.
- Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Additionally, tiny parts of these magnets are able to be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets is a challenge,
Pull force analysis
Best holding force of the magnet in ideal parameters – what contributes to it?
- on a base made of mild steel, optimally conducting the magnetic flux
- whose thickness is min. 10 mm
- with an polished contact surface
- under conditions of ideal adhesion (surface-to-surface)
- under vertical force vector (90-degree angle)
- in temp. approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Clearance – existence of foreign body (paint, dirt, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Direction of force – highest force is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Material type – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- Temperature influence – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was assessed by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate reduces the lifting capacity.
Warnings
Heat warning
Watch the temperature. Heating the magnet to high heat will ruin its magnetic structure and pulling force.
Precision electronics
Be aware: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your mobile, device, and GPS.
Warning for allergy sufferers
A percentage of the population suffer from a hypersensitivity to Ni, which is the common plating for neodymium magnets. Prolonged contact might lead to dermatitis. We strongly advise use protective gloves.
This is not a toy
Only for adults. Small elements pose a choking risk, leading to serious injuries. Keep away from children and animals.
Combustion hazard
Dust produced during machining of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Hand protection
Large magnets can break fingers instantly. Do not place your hand between two strong magnets.
Health Danger
Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Safe operation
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Material brittleness
Watch out for shards. Magnets can fracture upon violent connection, launching shards into the air. Eye protection is mandatory.
Electronic devices
Do not bring magnets near a wallet, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.
