Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- They do not lose magnetism, even over approximately ten years – the drop in strength is only ~1% (based on measurements),
- They maintain their magnetic properties even under close interference source,
- Thanks to the elegant finish, the coating of nickel, gold, or silver-plated gives an elegant appearance,
- Magnets exhibit huge magnetic induction on the outer layer,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Possibility of precise machining and adapting to individual requirements,
- Wide application in high-tech industry – they are utilized in mass storage devices, electric drive systems, advanced medical instruments, as well as multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise 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 nuts and complex forms in magnets, we recommend using a housing - magnetic mechanism.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these devices can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- using a sheet made of mild steel, functioning as a magnetic yoke
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- characterized by smoothness
- under conditions of no distance (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- at temperature room level
Practical aspects of lifting capacity – factors
- Distance (between the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to paint, corrosion or dirt).
- Load vector – highest force is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick plate causes magnetic saturation, causing part of the power to be wasted into the air.
- Material composition – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
- Surface finish – full contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature influence – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Magnetic media
Equipment safety: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, timepieces).
Pacemakers
Health Alert: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Hand protection
Large magnets can break fingers in a fraction of a second. Do not put your hand betwixt two strong magnets.
Powerful field
Handle magnets with awareness. Their powerful strength can shock even professionals. Stay alert and do not underestimate their force.
Heat warning
Monitor thermal conditions. Heating the magnet to high heat will destroy its properties and pulling force.
Swallowing risk
These products are not suitable for play. Eating multiple magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and necessitates immediate surgery.
GPS and phone interference
A strong magnetic field interferes with the operation of compasses in smartphones and navigation systems. Keep magnets near a device to prevent damaging the sensors.
Metal Allergy
Certain individuals have a contact allergy to nickel, which is the standard coating for neodymium magnets. Prolonged contact might lead to skin redness. It is best to wear protective gloves.
Beware of splinters
Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Machining danger
Dust produced during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
