Advantages and disadvantages of Nd2Fe14B magnets.
Pros
- They do not lose power, even after nearly 10 years – the drop in power is only ~1% (according to tests),
- They have excellent resistance to magnetic field loss due to external magnetic sources,
- A magnet with a smooth gold surface has an effective appearance,
- Neodymium magnets create maximum magnetic induction on a small area, which increases force concentration,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures reaching 230°C and above...
- Possibility of custom machining and adjusting to defined conditions,
- Key role in high-tech industry – they are commonly used in HDD drives, electric drive systems, medical devices, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in compact constructions
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in strength. 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
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in producing threads and complicated shapes in magnets, we recommend using cover - magnetic mount.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets can be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Best holding force of the magnet in ideal parameters – what contributes to it?
- on a base made of mild steel, effectively closing the magnetic field
- with a thickness no less than 10 mm
- with an ground touching surface
- under conditions of no distance (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- in stable room temperature
Determinants of practical lifting force of a magnet
- Distance – existence of foreign body (rust, tape, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Steel thickness – too thin sheet causes magnetic saturation, causing part of the flux to be escaped into the air.
- Metal type – different alloys reacts the same. High carbon content worsen the attraction effect.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Warnings
Swallowing risk
Adult use only. Small elements can be swallowed, leading to serious injuries. Store out of reach of kids and pets.
Fragile material
Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
Protect data
Very strong magnetic fields can erase data on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Life threat
Warning for patients: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or request help to handle the magnets.
Skin irritation risks
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction happens, cease handling magnets and wear gloves.
Maximum temperature
Keep cool. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Serious injuries
Mind your fingers. Two large magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!
Fire risk
Machining of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Impact on smartphones
GPS units and smartphones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Caution required
Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
