Pros and cons of rare earth magnets.
Benefits
- Their power is durable, and after approximately ten years it decreases only by ~1% (theoretically),
- They possess excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
- In other words, due to the glossy layer of nickel, the element gains a professional look,
- Magnetic induction on the working part of the magnet is exceptional,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to the ability of precise molding and customization to unique solutions, NdFeB magnets can be produced in a variety of shapes and sizes, which amplifies use scope,
- Universal use in modern technologies – they are used in magnetic memories, electric drive systems, medical equipment, also industrial machines.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also increases their durability
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 extremely resistant to heat
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of creating nuts in the magnet and complex forms - recommended is cover - magnetic holder.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, tiny parts of these devices are able to complicate diagnosis medical when they are in the body.
- Due to neodymium price, their price exceeds standard values,
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what it depends on?
- with the application of a sheet made of low-carbon steel, ensuring full magnetic saturation
- with a thickness no less than 10 mm
- with a plane cleaned and smooth
- with total lack of distance (no impurities)
- for force acting at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Magnet lifting force in use – key factors
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Plate thickness – insufficiently thick plate does not accept the full field, causing part of the power to be escaped to the other side.
- Steel type – mild steel attracts best. Higher carbon content decrease magnetic permeability and lifting capacity.
- Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was measured with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Safe handling of NdFeB magnets
Finger safety
Pinching hazard: The attraction force is so immense that it can cause hematomas, pinching, and broken bones. Use thick gloves.
Eye protection
Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
GPS and phone interference
Navigation devices and mobile phones are highly susceptible to magnetism. Direct contact with a strong magnet can decalibrate the sensors in your phone.
Skin irritation risks
Studies show that the nickel plating (the usual finish) is a common allergen. If your skin reacts to metals, avoid touching magnets with bare hands and select coated magnets.
Caution required
Use magnets with awareness. Their huge power can surprise even professionals. Plan your moves and do not underestimate their force.
Implant safety
Warning for patients: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.
Dust is flammable
Fire hazard: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.
Heat warning
Avoid heat. Neodymium magnets are sensitive to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).
Electronic devices
Powerful magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Do not give to children
Adult use only. Tiny parts can be swallowed, causing serious injuries. Store away from kids and pets.
