Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They retain magnetic properties for almost 10 years – the drop is just ~1% (based on simulations),
- They are extremely resistant to demagnetization induced by external disturbances,
- In other words, due to the smooth surface of silver, the element looks attractive,
- Magnetic induction on the surface of the magnet turns out to be exceptional,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
- Thanks to the possibility of free shaping and customization to custom requirements, magnetic components can be created in a wide range of shapes and sizes, which amplifies use scope,
- Versatile presence in modern technologies – they are utilized in mass storage devices, electric motors, medical devices, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in miniature devices
Weaknesses
- At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- We suggest cover - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex forms.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which gains importance in the context of child safety. Furthermore, small components of these magnets can be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- using a sheet made of mild steel, acting as a magnetic yoke
- possessing a thickness of minimum 10 mm to ensure full flux closure
- characterized by lack of roughness
- under conditions of no distance (metal-to-metal)
- under axial force vector (90-degree angle)
- at room temperature
Key elements affecting lifting force
- Distance – existence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Load vector – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – too thin plate does not close the flux, causing part of the power to be escaped to the other side.
- Plate material – low-carbon steel gives the best results. Higher carbon content reduce magnetic permeability and lifting capacity.
- Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Temperature – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate decreases the holding force.
Warnings
Magnetic interference
Navigation devices and smartphones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.
Permanent damage
Regular neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Dust explosion hazard
Powder produced during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Do not underestimate power
Handle magnets with awareness. Their powerful strength can surprise even experienced users. Stay alert and respect their power.
Bodily injuries
Mind your fingers. Two large magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Electronic hazard
Avoid bringing magnets near a purse, computer, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
Protective goggles
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Wear goggles.
Choking Hazard
NdFeB magnets are not toys. Eating multiple magnets may result in them attracting across intestines, which constitutes a critical condition and requires immediate surgery.
Avoid contact if allergic
A percentage of the population have a contact allergy to nickel, which is the common plating for neodymium magnets. Frequent touching can result in dermatitis. We strongly advise use protective gloves.
ICD Warning
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
