Pros as well as cons of rare earth magnets.
Advantages
- Their strength remains stable, and after approximately 10 years it decreases only by ~1% (theoretically),
- Magnets very well protect themselves against demagnetization caused by ambient magnetic noise,
- Thanks to the metallic finish, the plating of nickel, gold-plated, or silver-plated gives an professional appearance,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Neodymium magnets are characterized by very 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...
- Considering the potential of flexible forming and adaptation to individualized needs, magnetic components can be produced in a wide range of geometric configurations, which increases their versatility,
- Key role in high-tech industry – they are used in mass storage devices, electric motors, medical equipment, as well as modern systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. 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
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of creating threads in the magnet and complicated forms - recommended is casing - magnet mounting.
- Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these products can disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Maximum lifting capacity of the magnet – what affects it?
- on a plate made of mild steel, perfectly concentrating the magnetic field
- possessing a massiveness of at least 10 mm to ensure full flux closure
- characterized by even structure
- with total lack of distance (without coatings)
- under axial force vector (90-degree angle)
- at ambient temperature room level
Lifting capacity in practice – influencing factors
- Air gap (betwixt the magnet and the metal), since even a microscopic clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Chemical composition of the base – mild steel attracts best. Alloy steels lower magnetic properties and holding force.
- Plate texture – ground elements ensure maximum contact, which improves force. Uneven metal weaken the grip.
- Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate decreases the holding force.
Safe handling of neodymium magnets
Finger safety
Mind your fingers. Two large magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!
Allergy Warning
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, immediately stop handling magnets and use protective gear.
Eye protection
NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets leads to them breaking into shards.
Implant safety
Individuals with a heart stimulator have to keep an absolute distance from magnets. The magnetic field can interfere with the functioning of the life-saving device.
Machining danger
Powder created during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Product not for children
Adult use only. Small elements can be swallowed, causing serious injuries. Store away from kids and pets.
Electronic hazard
Do not bring magnets near a wallet, laptop, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.
Thermal limits
Control the heat. Heating the magnet to high heat will permanently weaken its properties and pulling force.
Handling rules
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Compass and GPS
A strong magnetic field interferes with the operation of magnetometers in smartphones and GPS navigation. Do not bring magnets close to a smartphone to avoid damaging the sensors.
