Advantages as well as disadvantages of rare earth magnets.
Pros
- They have stable power, and over around 10 years their performance decreases symbolically – ~1% (in testing),
- Magnets perfectly defend themselves against loss of magnetization caused by foreign field sources,
- Thanks to the elegant finish, the layer of nickel, gold-plated, or silver-plated gives an professional appearance,
- Magnets have extremely high magnetic induction on the active area,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to flexibility in forming and the capacity to modify to complex applications,
- Significant place in modern industrial fields – they find application in HDD drives, drive modules, advanced medical instruments, as well as industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Disadvantages
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and 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
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of producing threads in the magnet and complicated forms - preferred is a housing - magnetic holder.
- Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these products can complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what affects it?
- with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
- possessing a massiveness of at least 10 mm to avoid saturation
- with a plane free of scratches
- without any insulating layer between the magnet and steel
- under perpendicular force vector (90-degree angle)
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Distance (betwixt the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Plate thickness – too thin plate does not accept the full field, causing part of the flux to be escaped to the other side.
- Plate material – mild steel gives the best results. Higher carbon content reduce magnetic permeability and holding force.
- Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature – temperature increase results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Precautions when working with neodymium magnets
Powerful field
Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Shattering risk
Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Nickel coating and allergies
Some people suffer from a contact allergy to nickel, which is the common plating for NdFeB magnets. Frequent touching can result in dermatitis. We strongly advise wear safety gloves.
Do not overheat magnets
Control the heat. Heating the magnet above 80 degrees Celsius will ruin its properties and pulling force.
Danger to the youngest
Product intended for adults. Tiny parts can be swallowed, causing serious injuries. Keep away from kids and pets.
Threat to navigation
A strong magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Maintain magnets close to a device to prevent damaging the sensors.
Keep away from computers
Very strong magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.
Warning for heart patients
Individuals with a ICD have to keep an safe separation from magnets. The magnetism can disrupt the functioning of the life-saving device.
Serious injuries
Risk of injury: The pulling power is so great that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
Dust is flammable
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
