Strengths as well as weaknesses of rare earth magnets.
Strengths
- They retain attractive force for around 10 years – the drop is just ~1% (according to analyses),
- They feature excellent resistance to weakening of magnetic properties as a result of opposing magnetic fields,
- In other words, due to the aesthetic layer of gold, the element gains visual value,
- Magnets exhibit impressive magnetic induction on the outer side,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in constructing and the capacity to customize to unusual requirements,
- Versatile presence in modern industrial fields – they are commonly used in magnetic memories, brushless drives, advanced medical instruments, as well as complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We suggest cover - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated forms.
- Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, small elements of these magnets are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Maximum holding power of the magnet – what affects it?
- using a sheet made of high-permeability steel, acting as a magnetic yoke
- with a thickness no less than 10 mm
- characterized by smoothness
- with direct contact (without coatings)
- under axial force vector (90-degree angle)
- at temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys attracts identically. High carbon content weaken the attraction effect.
- Surface structure – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal factor – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was assessed using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate reduces the holding force.
Safety rules for work with NdFeB magnets
Safe distance
Avoid bringing magnets near a wallet, computer, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Health Danger
Patients with a ICD have to maintain an absolute distance from magnets. The magnetism can stop the functioning of the implant.
Skin irritation risks
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness happens, cease working with magnets and use protective gear.
Phone sensors
Navigation devices and smartphones are extremely susceptible to magnetism. Close proximity with a strong magnet can permanently damage the internal compass in your phone.
Caution required
Use magnets consciously. Their powerful strength can shock even professionals. Stay alert and respect their force.
Magnets are brittle
Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Demagnetization risk
Watch the temperature. Exposing the magnet to high heat will permanently weaken its magnetic structure and pulling force.
Dust is flammable
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Finger safety
Mind your fingers. Two powerful magnets will join immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Do not give to children
These products are not toys. Accidental ingestion of several magnets may result in them pinching intestinal walls, which poses a critical condition and necessitates immediate surgery.
