Strengths as well as weaknesses of rare earth magnets.
Strengths
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- Magnets effectively defend themselves against loss of magnetization caused by ambient magnetic noise,
- In other words, due to the smooth finish of silver, the element looks attractive,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
- Considering the option of flexible shaping and customization to specialized needs, NdFeB magnets can be produced in a variety of shapes and sizes, which increases their versatility,
- Fundamental importance in modern industrial fields – they find application in HDD drives, electric motors, advanced medical instruments, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in compact constructions
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in strength. 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 usually 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.
- Limited possibility of making threads in the magnet and complicated shapes - recommended is cover - magnetic holder.
- Health risk resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small elements of these products are able to be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- using a sheet made of high-permeability steel, serving as a ideal flux conductor
- possessing a thickness of minimum 10 mm to avoid saturation
- with an ground touching surface
- 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 lifting force in real conditions
- Distance (betwixt the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Load vector – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick plate causes magnetic saturation, causing part of the flux to be wasted into the air.
- Material type – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
- Thermal environment – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate reduces the holding force.
Precautions when working with neodymium magnets
Nickel allergy
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, immediately stop handling magnets and wear gloves.
Beware of splinters
Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
Life threat
Life threat: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
GPS Danger
GPS units and mobile phones are extremely susceptible to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Machining danger
Combustion risk: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.
Pinching danger
Big blocks can crush fingers in a fraction of a second. Do not put your hand betwixt two strong magnets.
Do not underestimate power
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
No play value
Absolutely store magnets away from children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are fatal.
Operating temperature
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Protect data
Avoid bringing magnets near a wallet, laptop, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
