Strengths as well as weaknesses of rare earth magnets.
Benefits
- They retain attractive force for around 10 years – the loss is just ~1% (in theory),
- They are resistant to demagnetization induced by external disturbances,
- A magnet with a shiny nickel surface has an effective appearance,
- Neodymium magnets generate maximum magnetic induction on a small area, which increases force concentration,
- 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...
- Possibility of precise creating as well as adapting to precise applications,
- Wide application in electronics industry – they are commonly used in computer drives, electromotive mechanisms, medical devices, also other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Limitations
- At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating threads and complex shapes in magnets, we recommend using a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. Furthermore, small components of these magnets are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Highest magnetic holding force – what affects it?
- with the use of a yoke made of special test steel, guaranteeing maximum field concentration
- whose transverse dimension reaches at least 10 mm
- with a plane cleaned and smooth
- with zero gap (without impurities)
- during detachment in a direction vertical to the mounting surface
- at standard ambient temperature
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Direction of force – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface structure – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, however under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate decreases the holding force.
Safety rules for work with neodymium magnets
Dust explosion hazard
Mechanical processing of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Immense force
Be careful. Neodymium magnets act from a long distance and snap with massive power, often faster than you can move away.
Beware of splinters
Neodymium magnets are ceramic materials, meaning they are very brittle. Impact of two magnets leads to them cracking into shards.
Implant safety
Individuals with a heart stimulator must maintain an safe separation from magnets. The magnetism can interfere with the operation of the life-saving device.
Protect data
Avoid bringing magnets close to a wallet, computer, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.
Compass and GPS
A strong magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Maintain magnets near a device to prevent damaging the sensors.
Demagnetization risk
Do not overheat. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Choking Hazard
Adult use only. Tiny parts pose a choking risk, causing intestinal necrosis. Store out of reach of kids and pets.
Skin irritation risks
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, cease handling magnets and wear gloves.
Serious injuries
Large magnets can break fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.
