Advantages and disadvantages of neodymium magnets.
Advantages
- They retain full power for almost 10 years – the drop is just ~1% (in theory),
- Magnets perfectly defend themselves against loss of magnetization caused by foreign field sources,
- In other words, due to the reflective surface of nickel, the element becomes visually attractive,
- Magnetic induction on the surface of the magnet turns out to be impressive,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Considering the possibility of free shaping and customization to individualized projects, neodymium magnets can be modeled in a variety of shapes and sizes, which amplifies use scope,
- Key role in future technologies – they are commonly used in magnetic memories, electromotive mechanisms, precision medical tools, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in compact constructions
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in force. 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 oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited ability of making nuts in the magnet and complex shapes - preferred is a housing - magnetic holder.
- Health risk related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. Additionally, tiny parts of these magnets are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Maximum lifting capacity of the magnet – what it depends on?
- with the application of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a massiveness of at least 10 mm to avoid saturation
- characterized by lack of roughness
- under conditions of ideal adhesion (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- at room temperature
Key elements affecting lifting force
- Gap (between the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, corrosion or dirt).
- Load vector – maximum parameter is available only during perpendicular pulling. The shear force of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick sheet does not accept the full field, causing part of the flux to be wasted to the other side.
- Steel grade – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature influence – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet’s surface and the plate lowers the holding force.
Warnings
Handling rules
Use magnets consciously. Their immense force can shock even professionals. Be vigilant and do not underestimate their force.
Do not drill into magnets
Combustion risk: Neodymium dust is explosive. Avoid machining magnets in home conditions as this may cause fire.
Data carriers
Avoid bringing magnets near a purse, laptop, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Adults only
Absolutely store magnets away from children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are life-threatening.
Nickel coating and allergies
Medical facts indicate that the nickel plating (the usual finish) is a common allergen. If you have an allergy, prevent direct skin contact or choose encased magnets.
Risk of cracking
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Danger to pacemakers
Patients with a pacemaker have to keep an large gap from magnets. The magnetic field can stop the operation of the implant.
Power loss in heat
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. This process is irreversible.
Serious injuries
Mind your fingers. Two large magnets will join instantly with a force of massive weight, destroying everything in their path. Be careful!
Magnetic interference
Note: rare earth magnets generate a field that interferes with precision electronics. Keep a safe distance from your mobile, tablet, and GPS.
