Advantages as well as disadvantages of neodymium magnets.
Pros
- Their magnetic field is durable, and after approximately 10 years it decreases only by ~1% (theoretically),
- They do not lose their magnetic properties even under strong external field,
- Thanks to the reflective finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an clean appearance,
- Magnets are characterized by huge magnetic induction on the active area,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to modularity in forming and the capacity to modify to individual projects,
- Wide application in advanced technology sectors – they serve a role in data components, drive modules, diagnostic systems, also multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Cons
- At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as 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 strength decreases (depending on the size, as well as 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 start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited ability of making nuts in the magnet and complicated shapes - recommended is casing - magnetic holder.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Furthermore, small components of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- Due to expensive raw materials, their price is higher than average,
Pull force analysis
Highest magnetic holding force – what it depends on?
- using a base made of low-carbon steel, functioning as a ideal flux conductor
- with a cross-section of at least 10 mm
- characterized by even structure
- without the slightest insulating layer between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- at conditions approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Metal type – not every steel reacts the same. High carbon content worsen the attraction effect.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was determined using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Implant safety
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Cards and drives
Avoid bringing magnets near a purse, laptop, or screen. The magnetism can destroy these devices and erase data from cards.
Nickel allergy
Nickel alert: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, immediately stop handling magnets and wear gloves.
Mechanical processing
Combustion risk: Rare earth powder is explosive. Do not process magnets in home conditions as this may cause fire.
Serious injuries
Protect your hands. Two powerful magnets will join instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Heat warning
Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. The loss of strength is permanent.
Do not give to children
Adult use only. Small elements can be swallowed, leading to intestinal necrosis. Store out of reach of children and animals.
Magnetic interference
Remember: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a separation from your phone, tablet, and GPS.
Conscious usage
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Beware of splinters
NdFeB magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets leads to them shattering into shards.
