Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- They do not lose power, even during around 10 years – the decrease in lifting capacity is only ~1% (according to tests),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the working part of the magnet turns out to be very high,
- 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...
- Due to the option of accurate shaping and customization to unique needs, NdFeB magnets can be created in a broad palette of geometric configurations, which makes them more universal,
- Fundamental importance in advanced technology sectors – they are used in hard drives, electric drive systems, medical equipment, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in compact constructions
Disadvantages
- At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Limited ability of making nuts in the magnet and complex shapes - preferred is casing - magnet mounting.
- Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting force for a neodymium magnet – what it depends on?
- with the contact of a yoke made of low-carbon steel, ensuring full magnetic saturation
- possessing a thickness of at least 10 mm to ensure full flux closure
- with an polished contact surface
- under conditions of ideal adhesion (surface-to-surface)
- under axial force direction (90-degree angle)
- at standard ambient temperature
Lifting capacity in real conditions – factors
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
- Plate thickness – insufficiently thick plate causes magnetic saturation, causing part of the flux to be escaped to the other side.
- Chemical composition of the base – mild steel attracts best. Higher carbon content reduce magnetic properties and lifting capacity.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Precautions when working with neodymium magnets
Choking Hazard
Product intended for adults. Tiny parts can be swallowed, causing serious injuries. Keep out of reach of kids and pets.
Nickel allergy
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction happens, immediately stop working with magnets and use protective gear.
Magnets are brittle
Protect your eyes. Magnets can explode upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.
Heat sensitivity
Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.
Handling rules
Use magnets consciously. Their powerful strength can shock even professionals. Plan your moves and do not underestimate their force.
Medical implants
People with a ICD have to keep an safe separation from magnets. The magnetism can stop the operation of the implant.
Crushing force
Risk of injury: The pulling power is so immense that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
Precision electronics
Navigation devices and smartphones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Mechanical processing
Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Safe distance
Intense magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
