Advantages and disadvantages of rare earth magnets.
Advantages
- Their magnetic field is durable, and after approximately 10 years it drops only by ~1% (theoretically),
- They are resistant to demagnetization induced by external magnetic fields,
- By covering with a decorative coating of silver, the element presents an modern look,
- Magnetic induction on the working layer of the magnet turns out to be strong,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Thanks to versatility in shaping and the ability to modify to client solutions,
- Key role in innovative solutions – they are commonly used in mass storage devices, brushless drives, advanced medical instruments, and technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating nuts and complicated shapes in magnets, we recommend using a housing - magnetic mechanism.
- Health risk resulting from small fragments of magnets are risky, if swallowed, which becomes key in the context of child safety. Furthermore, small components of these products are able to disrupt the diagnostic process medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- on a base made of mild steel, effectively closing the magnetic flux
- with a thickness minimum 10 mm
- with an ground touching surface
- under conditions of ideal adhesion (metal-to-metal)
- under axial force vector (90-degree angle)
- at room temperature
Magnet lifting force in use – key factors
- Distance – existence of any layer (rust, dirt, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Angle of force application – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick steel does not close the flux, causing part of the power to be escaped to the other side.
- Material type – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
- Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, however under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate reduces the load capacity.
H&S for magnets
This is not a toy
NdFeB magnets are not suitable for play. Swallowing multiple magnets may result in them attracting across intestines, which poses a direct threat to life and requires urgent medical intervention.
Demagnetization risk
Keep cool. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Immense force
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Precision electronics
Remember: rare earth magnets produce a field that disrupts sensitive sensors. Keep a separation from your phone, device, and GPS.
Fragile material
Beware of splinters. Magnets can explode upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.
Medical interference
Warning for patients: Powerful magnets disrupt electronics. Keep at least 30 cm distance or ask another person to work with the magnets.
Bone fractures
Risk of injury: The pulling power is so immense that it can result in blood blisters, crushing, and broken bones. Use thick gloves.
Machining danger
Dust generated during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Electronic hazard
Very strong magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
Allergy Warning
Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, prevent direct skin contact or choose versions in plastic housing.
