Pros and cons of rare earth magnets.
Strengths
- They do not lose power, even over approximately 10 years – the decrease in lifting capacity is only ~1% (according to tests),
- They have excellent resistance to magnetic field loss due to opposing magnetic fields,
- In other words, due to the reflective layer of gold, the element becomes visually attractive,
- The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of exact forming as well as modifying to concrete needs,
- Significant place in future technologies – they find application in hard drives, motor assemblies, advanced medical instruments, also industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Limitations
- To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- 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, 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 those in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of producing threads in the magnet and complicated forms - recommended is a housing - mounting mechanism.
- Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical after entering the body.
- Due to neodymium price, their price is relatively high,
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- with the use of a yoke made of special test steel, ensuring full magnetic saturation
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with a plane cleaned and smooth
- without the slightest air gap between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- at conditions approx. 20°C
Determinants of practical lifting force of a magnet
- Clearance – existence of any layer (rust, tape, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Load vector – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin plate does not accept the full field, causing part of the flux to be wasted into the air.
- Steel grade – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
- Surface finish – full contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate decreases the lifting capacity.
Precautions when working with NdFeB magnets
Warning for allergy sufferers
Certain individuals have a contact allergy to nickel, which is the common plating for neodymium magnets. Extended handling might lead to an allergic reaction. It is best to wear protective gloves.
Threat to navigation
A powerful magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Maintain magnets near a smartphone to avoid breaking the sensors.
Health Danger
For implant holders: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
Handling guide
Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Electronic hazard
Equipment safety: Strong magnets can damage data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).
Magnets are brittle
Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Maximum temperature
Keep cool. NdFeB magnets are sensitive to heat. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Flammability
Machining of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Danger to the youngest
Product intended for adults. Tiny parts can be swallowed, leading to serious injuries. Keep out of reach of kids and pets.
Physical harm
Big blocks can break fingers in a fraction of a second. Do not place your hand between two attracting surfaces.
