Strengths and weaknesses of neodymium magnets.
Pros
- They have stable power, and over around 10 years their performance decreases symbolically – ~1% (in testing),
- They have excellent resistance to magnetic field loss when exposed to external fields,
- A magnet with a smooth gold surface is more attractive,
- Neodymium magnets ensure maximum magnetic induction on a their surface, which increases force concentration,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- In view of the ability of precise forming and adaptation to specialized projects, magnetic components can be manufactured in a wide range of geometric configurations, which expands the range of possible applications,
- Wide application in advanced technology sectors – they are utilized in HDD drives, electric motors, advanced medical instruments, and other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- At very strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power 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
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Limited ability of producing nuts in the magnet and complex shapes - recommended is cover - magnet mounting.
- Possible danger related to microscopic parts 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 be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Maximum lifting capacity of the magnet – what it depends on?
- with the contact of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- whose thickness equals approx. 10 mm
- with a surface perfectly flat
- with direct contact (no coatings)
- during pulling in a direction perpendicular to the mounting surface
- at room temperature
Magnet lifting force in use – key factors
- Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel grade – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal weaken the grip.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was determined using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
H&S for magnets
Pacemakers
Individuals with a ICD must maintain an large gap from magnets. The magnetism can stop the operation of the implant.
Data carriers
Powerful magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Maximum temperature
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
Sensitization to coating
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid touching magnets with bare hands or select versions in plastic housing.
Protective goggles
NdFeB magnets are sintered ceramics, which means they are very brittle. Collision of two magnets will cause them shattering into shards.
Handling guide
Handle magnets with awareness. Their immense force can shock even experienced users. Be vigilant and do not underestimate their force.
Bodily injuries
Large magnets can crush fingers in a fraction of a second. Under no circumstances put your hand between two strong magnets.
Dust explosion hazard
Dust produced during cutting of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
This is not a toy
Absolutely keep magnets out of reach of children. Choking hazard is significant, and the effects of magnets connecting inside the body are tragic.
Compass and GPS
A powerful magnetic field negatively affects the operation of compasses in phones and GPS navigation. Maintain magnets close to a smartphone to prevent breaking the sensors.
