Advantages as well as disadvantages of rare earth magnets.
Strengths
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
- They are extremely resistant to demagnetization induced by external field influence,
- The use of an refined coating of noble metals (nickel, gold, silver) causes the element to look better,
- Magnetic induction on the working part of the magnet turns out to be impressive,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to freedom in forming and the ability to modify to client solutions,
- Significant place in modern technologies – they are utilized in data components, motor assemblies, precision medical tools, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in miniature devices
Disadvantages
- At strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited possibility of making nuts in the magnet and complex forms - preferred is cover - magnetic holder.
- Possible danger related to microscopic parts of magnets are risky, if swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these devices can be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Highest magnetic holding force – what affects it?
- on a plate made of structural steel, perfectly concentrating the magnetic flux
- with a thickness minimum 10 mm
- with an ideally smooth touching surface
- with total lack of distance (without paint)
- for force acting at a right angle (pull-off, not shear)
- at room temperature
Determinants of practical lifting force of a magnet
- Gap (betwixt the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Direction of force – highest force is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material type – the best choice is pure iron steel. Stainless steels may have worse magnetic properties.
- Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
H&S for magnets
Threat to navigation
Remember: neodymium magnets generate a field that disrupts precision electronics. Keep a safe distance from your mobile, tablet, and GPS.
Danger to pacemakers
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Choking Hazard
Always store magnets away from children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are tragic.
Hand protection
Large magnets can smash fingers in a fraction of a second. Do not put your hand betwixt two attracting surfaces.
Threat to electronics
Very strong magnetic fields can erase data on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Heat sensitivity
Control the heat. Heating the magnet to high heat will destroy its properties and pulling force.
Metal Allergy
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness occurs, immediately stop handling magnets and wear gloves.
Combustion hazard
Powder produced during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Eye protection
Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Handling guide
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
