Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
- Magnets perfectly defend themselves against loss of magnetization caused by ambient magnetic noise,
- Thanks to the shimmering finish, the coating of nickel, gold-plated, or silver gives an modern appearance,
- They feature high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Thanks to freedom in forming and the ability to customize to complex applications,
- Fundamental importance in advanced technology sectors – they are utilized in data components, drive modules, diagnostic systems, as well as technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- 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 prevent oxidation as well as corrosion.
- Due to limitations in realizing nuts and complex shapes in magnets, we propose using casing - magnetic mount.
- Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these magnets can disrupt the diagnostic process medical after entering the body.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- on a plate made of mild steel, effectively closing the magnetic flux
- with a thickness minimum 10 mm
- with an ground contact surface
- with zero gap (without paint)
- under vertical force direction (90-degree angle)
- at temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Space between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Plate material – low-carbon steel attracts best. Higher carbon content lower magnetic properties and lifting capacity.
- Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity was determined by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Safe handling of NdFeB magnets
Immense force
Exercise caution. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can react.
Skin irritation risks
Some people suffer from a sensitization to Ni, which is the common plating for neodymium magnets. Prolonged contact can result in a rash. It is best to use protective gloves.
Material brittleness
Neodymium magnets are sintered ceramics, which means they are very brittle. Impact of two magnets leads to them cracking into small pieces.
Pinching danger
Danger of trauma: The attraction force is so great that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Compass and GPS
A powerful magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Do not bring magnets near a smartphone to avoid breaking the sensors.
Heat warning
Control the heat. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
ICD Warning
For implant holders: Strong magnetic fields affect medical devices. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Fire warning
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Keep away from children
Absolutely keep magnets away from children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are tragic.
Protect data
Equipment safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, medical aids, timepieces).
