Advantages and disadvantages of neodymium magnets.
Benefits
- Their magnetic field is durable, and after around 10 years it decreases only by ~1% (according to research),
- Neodymium magnets are exceptionally resistant to magnetic field loss caused by magnetic disturbances,
- In other words, due to the shiny layer of silver, the element is aesthetically pleasing,
- Magnetic induction on the working part of the magnet is maximum,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- In view of the option of accurate molding and customization to custom needs, neodymium magnets can be manufactured in a wide range of forms and dimensions, which amplifies use scope,
- Versatile presence in high-tech industry – they are utilized in HDD drives, brushless drives, diagnostic systems, as well as modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of creating nuts in the magnet and complicated shapes - preferred is cover - magnet mounting.
- Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products 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
Optimal lifting capacity of a neodymium magnet – what it depends on?
- using a base made of low-carbon steel, serving as a magnetic yoke
- with a cross-section minimum 10 mm
- characterized by smoothness
- without any insulating layer between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at room temperature
Determinants of lifting force in real conditions
- Distance (between the magnet and the metal), as even a tiny clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys attracts identically. High carbon content weaken the attraction effect.
- Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate reduces the load capacity.
Warnings
Eye protection
Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Caution required
Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Medical interference
Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
Electronic devices
Very strong magnetic fields can destroy records on payment cards, HDDs, and storage devices. Stay away of at least 10 cm.
Compass and GPS
Navigation devices and mobile phones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.
Heat warning
Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Hand protection
Large magnets can crush fingers instantly. Under no circumstances place your hand between two strong magnets.
Keep away from children
Absolutely keep magnets out of reach of children. Choking hazard is significant, and the effects of magnets clamping inside the body are fatal.
Dust explosion hazard
Fire hazard: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.
Warning for allergy sufferers
Certain individuals have a contact allergy to nickel, which is the common plating for neodymium magnets. Prolonged contact might lead to a rash. We strongly advise wear safety gloves.
