Advantages as well as disadvantages of rare earth magnets.
Strengths
- They retain attractive force for around 10 years – the drop is just ~1% (according to analyses),
- Neodymium magnets prove to be exceptionally resistant to demagnetization caused by external field sources,
- By using a lustrous coating of nickel, the element presents an modern look,
- Neodymium magnets achieve maximum magnetic induction on a their surface, which allows for strong attraction,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to modularity in forming and the ability to customize to individual projects,
- Key role in modern technologies – they serve a role in hard drives, electric motors, precision medical tools, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in compact constructions
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We recommend casing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated forms.
- Health risk resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child health protection. Additionally, small components of these magnets can complicate diagnosis medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum holding power of the magnet – what it depends on?
- on a base made of structural steel, effectively closing the magnetic flux
- whose thickness equals approx. 10 mm
- with a surface perfectly flat
- with zero gap (without coatings)
- during pulling in a direction vertical to the mounting surface
- at conditions approx. 20°C
What influences lifting capacity in practice
- Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Plate material – mild steel gives the best results. Higher carbon content decrease magnetic permeability and lifting capacity.
- Surface structure – the smoother and more polished the surface, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate decreases the load capacity.
Safe handling of NdFeB magnets
Fragile material
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Finger safety
Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!
Handling rules
Handle with care. Rare earth magnets act from a long distance and connect with massive power, often faster than you can react.
Metal Allergy
Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, prevent touching magnets with bare hands or opt for encased magnets.
Dust is flammable
Mechanical processing of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Heat sensitivity
Control the heat. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
GPS Danger
A strong magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Do not bring magnets near a smartphone to avoid damaging the sensors.
Magnetic media
Powerful magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.
Keep away from children
NdFeB magnets are not suitable for play. Accidental ingestion of multiple magnets may result in them connecting inside the digestive tract, which constitutes a direct threat to life and requires immediate surgery.
Medical interference
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
