Pros as well as cons of rare earth magnets.
Benefits
- They retain attractive force for almost 10 years – the loss is just ~1% (in theory),
- Magnets perfectly resist against demagnetization caused by external fields,
- In other words, due to the shiny finish of nickel, the element gains a professional look,
- Neodymium magnets deliver maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to the potential of accurate molding and adaptation to unique solutions, NdFeB magnets can be modeled in a wide range of geometric configurations, which makes them more universal,
- Universal use in advanced technology sectors – they are commonly used in hard drives, electromotive mechanisms, medical devices, as well as industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in creating nuts and complicated shapes in magnets, we propose using cover - magnetic mechanism.
- Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Furthermore, tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a block made of structural steel, perfectly concentrating the magnetic flux
- with a thickness minimum 10 mm
- with an polished touching surface
- under conditions of no distance (surface-to-surface)
- under perpendicular application of breakaway force (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Impact of factors on magnetic holding capacity in practice
- Gap (between the magnet and the metal), since even a tiny clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick plate causes magnetic saturation, causing part of the power to be wasted into the air.
- Material composition – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet’s surface and the plate reduces the holding force.
Safe handling of neodymium magnets
Thermal limits
Regular neodymium magnets (N-type) lose power when the temperature goes above 80°C. This process is irreversible.
Bodily injuries
Watch your fingers. Two powerful magnets will snap together instantly with a force of massive weight, crushing anything in their path. Be careful!
Material brittleness
Neodymium magnets are sintered ceramics, which means they are very brittle. Clashing of two magnets will cause them breaking into shards.
Precision electronics
Navigation devices and smartphones are highly susceptible to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.
Warning for heart patients
Warning for patients: Strong magnetic fields disrupt medical devices. Maintain at least 30 cm distance or request help to work with the magnets.
Flammability
Powder generated during grinding of magnets is combustible. Do not drill into magnets unless you are an expert.
Powerful field
Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Think ahead.
Nickel allergy
A percentage of the population experience a sensitization to nickel, which is the common plating for neodymium magnets. Extended handling may cause dermatitis. We strongly advise use safety gloves.
Danger to the youngest
Absolutely store magnets out of reach of children. Choking hazard is significant, and the effects of magnets clamping inside the body are very dangerous.
Cards and drives
Intense magnetic fields can destroy records on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
