Pros and cons of Nd2Fe14B magnets.
Benefits
- They have stable power, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
- They do not lose their magnetic properties even under strong external field,
- A magnet with a shiny nickel surface has better aesthetics,
- Magnetic induction on the surface of the magnet remains impressive,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to versatility in shaping and the ability to customize to unusual requirements,
- Key role in future technologies – they are commonly used in data components, brushless drives, advanced medical instruments, as well as industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- At strong impacts they can crack, therefore we advise placing them in steel cases. 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 power. 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
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic mount, due to difficulties in creating nuts inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, tiny parts of these devices can be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum lifting capacity of the magnet – what contributes to it?
- using a base made of low-carbon steel, acting as a circuit closing element
- possessing a massiveness of at least 10 mm to avoid saturation
- with a plane free of scratches
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction vertical to the mounting surface
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Clearance – existence of foreign body (paint, dirt, air) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Steel grade – the best choice is high-permeability steel. Cast iron may attract less.
- Surface quality – the more even the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was determined by applying 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 slight gap between the magnet’s surface and the plate lowers the holding force.
Warnings
Respect the power
Exercise caution. Neodymium magnets attract from a distance and snap with massive power, often quicker than you can react.
Maximum temperature
Control the heat. Heating the magnet to high heat will destroy its properties and pulling force.
Precision electronics
A powerful magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Maintain magnets near a device to avoid damaging the sensors.
Threat to electronics
Equipment safety: Strong magnets can damage payment cards and delicate electronics (heart implants, medical aids, timepieces).
Dust explosion hazard
Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.
ICD Warning
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Protective goggles
Beware of splinters. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
No play value
Strictly store magnets out of reach of children. Choking hazard is high, and the effects of magnets connecting inside the body are life-threatening.
Pinching danger
Big blocks can break fingers instantly. Under no circumstances place your hand betwixt two strong magnets.
Skin irritation risks
Some people have a contact allergy to Ni, which is the standard coating for NdFeB magnets. Extended handling can result in an allergic reaction. We strongly advise wear protective gloves.
