Strengths as well as weaknesses of rare earth magnets.
Benefits
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (according to literature),
- Magnets perfectly resist against loss of magnetization caused by ambient magnetic noise,
- By using a decorative layer of gold, the element has an proper look,
- They show high magnetic induction at the operating surface, which increases their power,
- 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...
- In view of the potential of accurate forming and customization to specialized needs, NdFeB magnets can be created in a wide range of forms and dimensions, which increases their versatility,
- Universal use in high-tech industry – they are used in computer drives, electromotive mechanisms, precision medical tools, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in small systems
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in force. 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
- 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 secure oxidation and corrosion.
- We suggest casing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Possible danger to health – tiny shards of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these products can be problematic in diagnostics 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
Best holding force of the magnet in ideal parameters – what it depends on?
- with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
- with a thickness no less than 10 mm
- characterized by lack of roughness
- under conditions of gap-free contact (metal-to-metal)
- for force applied at a right angle (in the magnet axis)
- at standard ambient temperature
Lifting capacity in real conditions – factors
- Air gap (betwixt the magnet and the plate), because even a microscopic clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to paint, corrosion or dirt).
- Angle of force application – maximum parameter is available only during perpendicular pulling. The shear force of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin steel does not accept the full field, causing part of the power to be lost to the other side.
- Plate material – mild steel gives the best results. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Surface finish – ideal contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was measured using a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Safety rules for work with neodymium magnets
Do not give to children
Strictly store magnets away from children. Choking hazard is significant, and the consequences of magnets connecting inside the body are very dangerous.
Fragile material
Watch out for shards. Magnets can explode upon violent connection, ejecting shards into the air. Eye protection is mandatory.
Immense force
Handle magnets with awareness. Their powerful strength can shock even experienced users. Stay alert and do not underestimate their force.
Impact on smartphones
Navigation devices and smartphones are highly sensitive to magnetic fields. Direct contact with a strong magnet can permanently damage the internal compass in your phone.
Dust explosion hazard
Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Danger to pacemakers
People with a pacemaker should keep an safe separation from magnets. The magnetic field can disrupt the operation of the implant.
Physical harm
Danger of trauma: The attraction force is so great that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.
Metal Allergy
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, immediately stop working with magnets and use protective gear.
Operating temperature
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.
Safe distance
Do not bring magnets near a purse, laptop, or screen. The magnetism can destroy these devices and erase data from cards.
