Strengths and weaknesses of neodymium magnets.
Advantages
- They have unchanged lifting capacity, and over around ten years their attraction force decreases symbolically – ~1% (in testing),
- They show high resistance to demagnetization induced by external field influence,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
- Thanks to freedom in designing and the ability to adapt to specific needs,
- Significant place in future technologies – they are utilized in data components, brushless drives, medical equipment, and modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Limitations
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Limited possibility of making threads in the magnet and complicated shapes - preferred is a housing - magnetic holder.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these products can be problematic in diagnostics medical in case of swallowing.
- Due to expensive raw materials, their price exceeds standard values,
Lifting parameters
Highest magnetic holding force – what it depends on?
- on a base made of mild steel, optimally conducting the magnetic field
- whose transverse dimension equals approx. 10 mm
- with an ground contact surface
- without the slightest air gap between the magnet and steel
- under vertical force vector (90-degree angle)
- in neutral thermal conditions
Determinants of lifting force in real conditions
- Distance – existence of foreign body (rust, tape, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys attracts identically. High carbon content weaken the attraction effect.
- Surface structure – the smoother and more polished the surface, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate lowers the holding force.
Warnings
Electronic devices
Do not bring magnets near a purse, computer, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Fire risk
Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.
Magnetic interference
Be aware: neodymium magnets generate a field that disrupts precision electronics. Keep a separation from your mobile, device, and GPS.
This is not a toy
Always store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are life-threatening.
Powerful field
Handle with care. Rare earth magnets attract from a distance and connect with huge force, often faster than you can react.
Medical implants
Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Warning for allergy sufferers
A percentage of the population suffer from a contact allergy to Ni, which is the common plating for NdFeB magnets. Frequent touching can result in an allergic reaction. We strongly advise use safety gloves.
Do not overheat magnets
Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.
Fragile material
Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Crushing risk
Risk of injury: The pulling power is so great that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
