Pros and cons of rare earth magnets.
Pros
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- They are noted for resistance to demagnetization induced by external disturbances,
- By using a decorative layer of nickel, the element has an proper look,
- Magnetic induction on the top side of the magnet turns out to be very high,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
- Possibility of detailed shaping and adjusting to individual conditions,
- Fundamental importance in modern technologies – they are used in computer drives, electric drive systems, medical devices, also other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- 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 experience a drop in power. Often, when the temperature exceeds 80°C, their power 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 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.
- We suggest casing - magnetic mount, due to difficulties in creating threads inside the magnet and complicated shapes.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these magnets can complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Maximum lifting capacity of the magnet – what affects it?
- with the application of a yoke made of special test steel, ensuring maximum field concentration
- whose thickness equals approx. 10 mm
- with a plane cleaned and smooth
- under conditions of no distance (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- at standard ambient temperature
What influences lifting capacity in practice
- Clearance – the presence of foreign body (rust, tape, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Plate material – low-carbon steel gives the best results. Alloy admixtures decrease magnetic permeability and lifting capacity.
- Smoothness – ideal contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet and the plate reduces the load capacity.
Safe handling of neodymium magnets
Do not drill into magnets
Machining of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Cards and drives
Avoid bringing magnets near a purse, laptop, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Phone sensors
Navigation devices and mobile phones are highly susceptible to magnetic fields. Direct contact with a strong magnet can ruin the sensors in your phone.
Medical implants
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Heat sensitivity
Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Safe operation
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Magnet fragility
Despite the nickel coating, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Allergy Warning
Studies show that nickel (standard magnet coating) is a common allergen. For allergy sufferers, avoid touching magnets with bare hands or select coated magnets.
Pinching danger
Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!
Danger to the youngest
These products are not toys. Swallowing multiple magnets can lead to them attracting across intestines, which constitutes a critical condition and necessitates urgent medical intervention.
