Strengths as well as weaknesses of rare earth magnets.
Pros
- They retain attractive force for around 10 years – the drop is just ~1% (based on simulations),
- They possess excellent resistance to magnetism drop as a result of external fields,
- Thanks to the glossy finish, the layer of Ni-Cu-Ni, gold, or silver gives an clean appearance,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to modularity in constructing and the ability to adapt to client solutions,
- Significant place in future technologies – they serve a role in data components, electric drive systems, precision medical tools, also multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- We recommend casing - magnetic mount, due to difficulties in producing nuts inside the magnet and complex forms.
- Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, 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
Optimal lifting capacity of a neodymium magnet – what it depends on?
- using a base made of high-permeability steel, acting as a magnetic yoke
- whose transverse dimension equals approx. 10 mm
- with an polished contact surface
- with total lack of distance (without paint)
- under perpendicular application of breakaway force (90-degree angle)
- in stable room temperature
Key elements affecting lifting force
- Distance (between the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is pure iron steel. Cast iron may attract less.
- Smoothness – ideal contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the holding force.
Safe handling of NdFeB magnets
Keep away from children
Strictly keep magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are tragic.
Precision electronics
Be aware: rare earth magnets produce a field that confuses precision electronics. Keep a separation from your phone, tablet, and navigation systems.
Pacemakers
For implant holders: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.
Safe distance
Very strong magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
Permanent damage
Keep cool. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
Powerful field
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Machining danger
Dust produced during cutting of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Magnets are brittle
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Collision of two magnets leads to them shattering into shards.
Physical harm
Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Nickel allergy
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness occurs, immediately stop handling magnets and use protective gear.
