Pros as well as cons of neodymium magnets.
Advantages
- They do not lose magnetism, even after nearly ten years – the drop in power is only ~1% (according to tests),
- They are noted for resistance to demagnetization induced by external field influence,
- A magnet with a smooth nickel surface has better aesthetics,
- Magnetic induction on the top side of the magnet is very high,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures approaching 230°C and above...
- Possibility of exact shaping as well as optimizing to atypical applications,
- Key role in modern technologies – they are used in hard drives, drive modules, precision medical tools, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in compact constructions
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets experience 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 start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- We recommend a housing - magnetic holder, due to difficulties in realizing threads inside the magnet and complex forms.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Furthermore, small components of these devices are able to complicate diagnosis medical when they are in the body.
- With mass production the cost of neodymium magnets is economically unviable,
Pull force analysis
Highest magnetic holding force – what affects it?
- on a base made of mild steel, effectively closing the magnetic flux
- with a cross-section of at least 10 mm
- with an polished contact surface
- under conditions of ideal adhesion (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- in stable room temperature
Magnet lifting force in use – key factors
- Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Material composition – different alloys attracts identically. Alloy additives weaken the attraction effect.
- Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
- Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was measured by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the holding force is lower. In addition, even a small distance between the magnet and the plate decreases the holding force.
Precautions when working with NdFeB magnets
Machining danger
Fire hazard: Neodymium dust is explosive. Do not process magnets without safety gear as this risks ignition.
Respect the power
Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Crushing force
Large magnets can smash fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.
Compass and GPS
An intense magnetic field disrupts the operation of compasses in smartphones and navigation systems. Maintain magnets near a device to prevent damaging the sensors.
Safe distance
Device Safety: Neodymium magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, mechanical watches).
Pacemakers
Patients with a heart stimulator should keep an safe separation from magnets. The magnetic field can stop the operation of the life-saving device.
Power loss in heat
Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and strength.
Risk of cracking
Watch out for shards. Magnets can fracture upon violent connection, launching shards into the air. Eye protection is mandatory.
Adults only
These products are not toys. Swallowing several magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and necessitates immediate surgery.
Allergy Warning
A percentage of the population experience a sensitization to nickel, which is the standard coating for neodymium magnets. Extended handling can result in a rash. We suggest wear protective gloves.
