Pros as well as cons of neodymium magnets.
Benefits
- They retain magnetic properties for nearly 10 years – the loss is just ~1% (based on simulations),
- They retain their magnetic properties even under close interference source,
- Thanks to the shimmering finish, the plating of Ni-Cu-Ni, gold-plated, or silver gives an aesthetic appearance,
- Magnets exhibit extremely high magnetic induction on the outer layer,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of exact modeling as well as modifying to atypical conditions,
- Versatile presence in advanced technology sectors – they are commonly used in magnetic memories, drive modules, medical devices, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in small systems
Limitations
- At very strong impacts they can break, therefore we advise 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 strength. 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
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating nuts in the magnet and complicated shapes - preferred is cover - magnetic holder.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Furthermore, small elements of these devices are able to disrupt the diagnostic process medical after entering the body.
- With large orders the cost of neodymium magnets is economically unviable,
Holding force characteristics
Highest magnetic holding force – what it depends on?
- using a base made of mild steel, functioning as a magnetic yoke
- whose transverse dimension is min. 10 mm
- characterized by lack of roughness
- without any clearance between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Distance – existence of foreign body (rust, dirt, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Angle of force application – highest force is available only during perpendicular pulling. The shear force of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material composition – not every steel attracts identically. Alloy additives weaken the attraction effect.
- Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was assessed by applying a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet’s surface and the plate reduces the holding force.
Precautions when working with NdFeB magnets
Keep away from electronics
Be aware: neodymium magnets produce a field that confuses sensitive sensors. Keep a safe distance from your phone, device, and GPS.
Magnetic media
Avoid bringing magnets near a purse, computer, or screen. The magnetic field can destroy these devices and erase data from cards.
Handling guide
Exercise caution. Neodymium magnets act from a long distance and snap with massive power, often quicker than you can move away.
Hand protection
Danger of trauma: The attraction force is so great that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Combustion hazard
Powder created during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Demagnetization risk
Avoid heat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).
Life threat
Patients with a pacemaker have to maintain an safe separation from magnets. The magnetism can interfere with the operation of the life-saving device.
Nickel allergy
It is widely known that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, refrain from direct skin contact and opt for coated magnets.
Magnets are brittle
NdFeB magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets will cause them shattering into small pieces.
Choking Hazard
Strictly store magnets out of reach of children. Choking hazard is high, and the effects of magnets connecting inside the body are fatal.
