Pros and cons of Nd2Fe14B magnets.
Advantages
- They retain full power for around 10 years – the drop is just ~1% (according to analyses),
- They are extremely resistant to demagnetization induced by external field influence,
- Thanks to the reflective finish, the plating of Ni-Cu-Ni, gold-plated, or silver-plated gives an aesthetic appearance,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures reaching 230°C and above...
- Possibility of precise forming as well as adjusting to defined applications,
- Fundamental importance in modern industrial fields – they are utilized in data components, electromotive mechanisms, diagnostic systems, as well as multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- At very strong impacts they can break, therefore we advise placing them in steel cases. 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 strength. Often, when the temperature exceeds 80°C, their power 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Due to limitations in producing threads and complicated shapes in magnets, we propose using casing - magnetic mechanism.
- Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. It is also worth noting that small elements of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- using a sheet made of mild steel, acting as a ideal flux conductor
- with a thickness minimum 10 mm
- characterized by smoothness
- without the slightest insulating layer between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in stable room temperature
Practical lifting capacity: influencing factors
- Clearance – existence of any layer (paint, tape, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- 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.
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material type – the best choice is pure iron steel. Cast iron may attract less.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
- Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
H&S for magnets
Choking Hazard
NdFeB magnets are not intended for children. Swallowing several magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and necessitates immediate surgery.
Permanent damage
Regular neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.
Cards and drives
Do not bring magnets near a wallet, computer, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Eye protection
Protect your eyes. Magnets can explode upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
Handling rules
Exercise caution. Neodymium magnets act from a distance and snap with huge force, often faster than you can move away.
Pacemakers
People with a pacemaker should keep an safe separation from magnets. The magnetism can interfere with the operation of the implant.
Metal Allergy
Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, cease working with magnets and wear gloves.
Keep away from electronics
A powerful magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Maintain magnets close to a smartphone to avoid breaking the sensors.
Hand protection
Risk of injury: The attraction force is so immense that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.
Mechanical processing
Drilling and cutting of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
