Advantages as well as disadvantages of neodymium magnets.
Advantages
- They retain magnetic properties for almost 10 years – the loss is just ~1% (according to analyses),
- Magnets perfectly defend themselves against loss of magnetization caused by external fields,
- Thanks to the reflective finish, the layer of Ni-Cu-Ni, gold, or silver gives an modern appearance,
- Magnets are distinguished by maximum magnetic induction on the outer layer,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures approaching 230°C and above...
- Possibility of exact modeling and modifying to concrete conditions,
- Significant place in modern technologies – they are utilized in hard drives, motor assemblies, medical equipment, and technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Disadvantages
- At strong impacts they can break, therefore we recommend 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 strength. Often, when the temperature exceeds 80°C, their power 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 rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating threads and complex shapes in magnets, we propose using casing - magnetic holder.
- Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, small components of these magnets can be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets is economically unviable,
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- with the contact of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- whose transverse dimension equals approx. 10 mm
- characterized by lack of roughness
- without any air gap between the magnet and steel
- during pulling in a direction vertical to the plane
- in neutral thermal conditions
Determinants of lifting force in real conditions
- Air gap (betwixt the magnet and the metal), 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 varnish, rust or dirt).
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Base massiveness – too thin plate does not close the flux, causing part of the power to be wasted to the other side.
- Steel type – low-carbon steel gives the best results. Alloy admixtures lower magnetic properties and lifting capacity.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal environment – heating the magnet results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate decreases the lifting capacity.
Precautions when working with neodymium magnets
Power loss in heat
Control the heat. Heating the magnet to high heat will destroy its properties and pulling force.
Fragile material
Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Phone sensors
Note: neodymium magnets generate a field that interferes with sensitive sensors. Keep a separation from your phone, tablet, and navigation systems.
Implant safety
People with a ICD should keep an absolute distance from magnets. The magnetism can interfere with the operation of the life-saving device.
Do not underestimate power
Use magnets with awareness. Their immense force can surprise even professionals. Be vigilant and do not underestimate their force.
Skin irritation risks
Some people experience a contact allergy to Ni, which is the standard coating for NdFeB magnets. Extended handling might lead to an allergic reaction. We recommend use protective gloves.
Hand protection
Large magnets can smash fingers in a fraction of a second. Do not place your hand between two strong magnets.
Do not give to children
Neodymium magnets are not intended for children. Eating multiple magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and necessitates urgent medical intervention.
Protect data
Device Safety: Neodymium magnets can damage payment cards and sensitive devices (heart implants, hearing aids, timepieces).
Combustion hazard
Powder generated during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
