Other offers
Pros as well as cons of rare earth magnets.
Pros
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- They retain their magnetic properties even under external field action,
- In other words, due to the aesthetic layer of gold, the element gains visual value,
- Neodymium magnets ensure maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Considering the ability of accurate molding and customization to custom requirements, NdFeB magnets can be manufactured in a variety of forms and dimensions, which makes them more universal,
- Key role in modern technologies – they serve a role in HDD drives, drive modules, medical devices, and multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- At very 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 experience a drop in strength. Often, when the temperature exceeds 80°C, their power 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 suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing threads and complex forms in magnets, we propose using casing - magnetic mount.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these products are able to be problematic in diagnostics medical when they are in the body.
- Due to complex production process, their price is relatively high,
Pull force analysis
Magnetic strength at its maximum – what contributes to it?
- using a base made of high-permeability steel, functioning as a ideal flux conductor
- with a thickness minimum 10 mm
- with an ideally smooth contact surface
- with zero gap (without coatings)
- during detachment in a direction perpendicular to the plane
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Distance (between the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Chemical composition of the base – mild steel attracts best. Higher carbon content decrease magnetic properties and lifting capacity.
- Surface quality – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Temperature – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under shearing force the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate decreases the holding force.
Permanent damage
Standard neodymium magnets (grade N) lose power when the temperature exceeds 80°C. Damage is permanent.
This is not a toy
Neodymium magnets are not intended for children. Swallowing multiple magnets may result in them pinching intestinal walls, which constitutes a critical condition and requires urgent medical intervention.
Fire risk
Combustion risk: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.
Shattering risk
Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Metal Allergy
It is widely known that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or select encased magnets.
Warning for heart patients
Warning for patients: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
Serious injuries
Big blocks can break fingers instantly. Do not put your hand betwixt two attracting surfaces.
Immense force
Exercise caution. Neodymium magnets attract from a distance and snap with huge force, often quicker than you can move away.
Electronic devices
Avoid bringing magnets near a wallet, laptop, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
Keep away from electronics
Remember: rare earth magnets produce a field that disrupts sensitive sensors. Keep a separation from your mobile, tablet, and navigation systems.
