Strengths and weaknesses of rare earth magnets.
Pros
- They have stable power, and over more than 10 years their performance decreases symbolically – ~1% (according to theory),
- Magnets perfectly protect themselves against loss of magnetization caused by ambient magnetic noise,
- In other words, due to the shiny surface of nickel, the element becomes visually attractive,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- 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...
- Thanks to flexibility in forming and the capacity to adapt to complex applications,
- Fundamental importance in modern industrial fields – they are used in mass storage devices, electromotive mechanisms, precision medical tools, and modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Cons
- To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We suggest cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. It is also worth noting that tiny parts of these magnets can complicate diagnosis medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- with the application of a yoke made of special test steel, guaranteeing full magnetic saturation
- possessing a massiveness of at least 10 mm to avoid saturation
- characterized by even structure
- with direct contact (without paint)
- under perpendicular application of breakaway force (90-degree angle)
- at standard ambient temperature
Determinants of practical lifting force of a magnet
- Distance (between the magnet and the metal), as even a tiny clearance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, rust or debris).
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Material type – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was measured with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet’s surface and the plate decreases the holding force.
H&S for magnets
Combustion hazard
Powder created during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.
ICD Warning
People with a heart stimulator have to keep an large gap from magnets. The magnetism can stop the functioning of the implant.
Demagnetization risk
Avoid heat. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
Risk of cracking
Beware of splinters. Magnets can explode upon violent connection, ejecting shards into the air. Wear goggles.
GPS Danger
Navigation devices and smartphones are highly sensitive to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.
Electronic devices
Device Safety: Strong magnets can ruin data carriers and delicate electronics (heart implants, medical aids, timepieces).
Avoid contact if allergic
It is widely known that nickel (the usual finish) is a strong allergen. If you have an allergy, prevent direct skin contact or select encased magnets.
Respect the power
Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Physical harm
Mind your fingers. Two large magnets will join instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!
Do not give to children
Strictly keep magnets away from children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are fatal.
