Advantages as well as disadvantages of rare earth magnets.
Pros
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
- They maintain their magnetic properties even under external field action,
- A magnet with a metallic gold surface has an effective appearance,
- Magnets exhibit extremely high magnetic induction on the surface,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Possibility of accurate creating and modifying to precise conditions,
- Huge importance in modern industrial fields – they are used in magnetic memories, brushless drives, diagnostic systems, and complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of producing nuts in the magnet and complex shapes - recommended is casing - magnetic holder.
- Health risk resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these magnets are able to disrupt the diagnostic process medical after entering the body.
- Due to expensive raw materials, their price exceeds standard values,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a plate made of mild steel, perfectly concentrating the magnetic field
- with a cross-section no less than 10 mm
- characterized by smoothness
- under conditions of gap-free contact (metal-to-metal)
- during pulling in a direction vertical to the mounting surface
- at room temperature
Practical lifting capacity: influencing factors
- Distance – existence of foreign body (rust, dirt, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel gives the best results. Alloy admixtures decrease magnetic permeability and lifting capacity.
- Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet and the plate reduces the lifting capacity.
H&S for magnets
Keep away from computers
Do not bring magnets close to a wallet, computer, or screen. The magnetism can destroy these devices and erase data from cards.
Heat sensitivity
Watch the temperature. Exposing the magnet to high heat will ruin its properties and pulling force.
Metal Allergy
It is widely known that nickel (the usual finish) is a potent allergen. If your skin reacts to metals, avoid touching magnets with bare hands or choose versions in plastic housing.
Bone fractures
Big blocks can crush fingers instantly. Never put your hand between two attracting surfaces.
Fire risk
Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Health Danger
People with a ICD have to maintain an absolute distance from magnets. The magnetism can interfere with the functioning of the implant.
Precision electronics
GPS units and mobile phones are extremely susceptible to magnetism. Direct contact with a strong magnet can ruin the sensors in your phone.
This is not a toy
Always keep magnets away from children. Ingestion danger is significant, and the effects of magnets clamping inside the body are tragic.
Beware of splinters
NdFeB magnets are ceramic materials, meaning they are very brittle. Clashing of two magnets will cause them shattering into shards.
Respect the power
Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
