Pros as well as cons of rare earth magnets.
Pros
- Their power is durable, and after approximately 10 years it decreases only by ~1% (according to research),
- They do not lose their magnetic properties even under strong external field,
- In other words, due to the smooth finish of gold, the element gains visual value,
- Magnets are distinguished by extremely high magnetic induction on the outer side,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
- Possibility of individual forming as well as adjusting to concrete needs,
- Significant place in modern technologies – they are used in hard drives, electric drive systems, diagnostic systems, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in compact constructions
Disadvantages
- 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 raises their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in creating threads and complex forms in magnets, we propose using cover - magnetic mount.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these devices are able to disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price is higher than average,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a plate made of structural steel, effectively closing the magnetic field
- possessing a thickness of minimum 10 mm to avoid saturation
- with an ideally smooth touching surface
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at temperature room level
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Wall 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. High carbon content worsen the attraction effect.
- Surface condition – ground elements ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, whereas under shearing force the holding force is lower. Additionally, even a slight gap between the magnet and the plate lowers the load capacity.
Warnings
Thermal limits
Control the heat. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.
GPS Danger
Note: neodymium magnets generate a field that interferes with precision electronics. Maintain a separation from your phone, device, and GPS.
Nickel coating and allergies
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. For allergy sufferers, prevent touching magnets with bare hands and choose encased magnets.
Magnetic media
Powerful magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Handling rules
Use magnets with awareness. Their huge power can surprise even professionals. Plan your moves and respect their power.
Adults only
NdFeB magnets are not intended for children. Eating multiple magnets can lead to them attracting across intestines, which poses a critical condition and necessitates urgent medical intervention.
Protective goggles
Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Crushing force
Large magnets can crush fingers in a fraction of a second. Do not put your hand betwixt two strong magnets.
Implant safety
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Dust is flammable
Fire hazard: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
