Advantages as well as disadvantages of rare earth magnets.
Strengths
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (according to literature),
- Magnets perfectly protect themselves against loss of magnetization caused by ambient magnetic noise,
- By covering with a decorative layer of silver, the element gains an professional look,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Possibility of exact creating and optimizing to specific conditions,
- Fundamental importance in modern industrial fields – they serve a role in computer drives, brushless drives, diagnostic systems, and modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing threads and complicated shapes in magnets, we propose using casing - magnetic holder.
- Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. It is also worth noting that small components of these devices 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
Maximum magnetic pulling force – what it depends on?
- using a sheet made of low-carbon steel, serving as a magnetic yoke
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with a surface cleaned and smooth
- under conditions of gap-free contact (surface-to-surface)
- under perpendicular application of breakaway force (90-degree angle)
- at temperature room level
Lifting capacity in practice – influencing factors
- Clearance – existence of foreign body (rust, tape, air) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Plate material – low-carbon steel attracts best. Alloy admixtures decrease magnetic properties and lifting capacity.
- Smoothness – ideal contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
H&S for magnets
Phone sensors
A powerful magnetic field negatively affects the operation of magnetometers in smartphones and navigation systems. Do not bring magnets near a smartphone to prevent damaging the sensors.
Electronic devices
Data protection: Strong magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Bone fractures
Mind your fingers. Two powerful magnets will snap together instantly with a force of massive weight, destroying anything in their path. Be careful!
Powerful field
Use magnets consciously. Their immense force can surprise even experienced users. Plan your moves and respect their force.
Risk of cracking
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets will cause them cracking into shards.
Warning for allergy sufferers
It is widely known that the nickel plating (standard magnet coating) is a potent allergen. If your skin reacts to metals, refrain from direct skin contact and select encased magnets.
Power loss in heat
Avoid heat. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Combustion hazard
Fire warning: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.
Life threat
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Product not for children
Always store magnets away from children. Ingestion danger is high, and the effects of magnets connecting inside the body are life-threatening.
