Strengths as well as weaknesses of neodymium magnets.
Benefits
- They retain magnetic properties for almost ten years – the drop is just ~1% (in theory),
- Neodymium magnets are extremely resistant to demagnetization caused by external interference,
- A magnet with a shiny nickel surface has an effective appearance,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
- Thanks to freedom in designing and the ability to adapt to specific needs,
- Huge importance in future technologies – they are used in data components, brushless drives, precision medical tools, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in miniature devices
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also increases their 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, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of making nuts in the magnet and complicated shapes - recommended is casing - mounting mechanism.
- Health risk related to microscopic parts of magnets are risky, if swallowed, which gains importance in the context of child safety. Furthermore, tiny parts of these devices can disrupt the diagnostic process medical after entering the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum magnetic pulling force – what affects it?
- using a sheet made of mild steel, acting as a magnetic yoke
- with a cross-section of at least 10 mm
- with an ideally smooth touching surface
- under conditions of no distance (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Gap (betwixt the magnet and the metal), as even a tiny distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Steel thickness – insufficiently thick steel does not accept the full field, causing part of the flux to be wasted to the other side.
- Steel grade – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
- Surface quality – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate reduces the holding force.
H&S for magnets
Swallowing risk
Strictly store magnets away from children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are tragic.
Do not overheat magnets
Do not overheat. NdFeB magnets are sensitive to heat. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
Electronic devices
Avoid bringing magnets near a wallet, computer, or screen. The magnetic field can permanently damage these devices and erase data from cards.
Phone sensors
GPS units and smartphones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can permanently damage the sensors in your phone.
Medical implants
Warning for patients: Strong magnetic fields affect electronics. Keep at least 30 cm distance or ask another person to work with the magnets.
Metal Allergy
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness appears, immediately stop working with magnets and use protective gear.
Do not drill into magnets
Powder created during cutting of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Immense force
Handle magnets with awareness. Their immense force can shock even professionals. Plan your moves and respect their force.
Crushing risk
Large magnets can crush fingers instantly. Never place your hand between two strong magnets.
Risk of cracking
Despite metallic appearance, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
