Pros and cons of rare earth magnets.
Strengths
- They retain magnetic properties for almost ten years – the drop is just ~1% (based on simulations),
- Neodymium magnets prove to be exceptionally resistant to magnetic field loss caused by external interference,
- The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- They show high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Due to the option of accurate shaping and adaptation to individualized needs, neodymium magnets can be modeled in a variety of shapes and sizes, which expands the range of possible applications,
- Significant place in modern industrial fields – they are used in magnetic memories, electric drive systems, diagnostic systems, as well as complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- We recommend cover - magnetic mount, due to difficulties in creating threads inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Additionally, small elements of these devices are able to complicate diagnosis medical after entering the body.
- 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
Lifting parameters
Maximum magnetic pulling force – what affects it?
- using a base made of low-carbon steel, acting as a ideal flux conductor
- possessing a thickness of at least 10 mm to ensure full flux closure
- with a surface perfectly flat
- under conditions of no distance (surface-to-surface)
- during pulling in a direction vertical to the plane
- at standard ambient temperature
Determinants of lifting force in real conditions
- Distance (between the magnet and the metal), as even a very small distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, rust or debris).
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
- Steel thickness – too thin sheet does not close the flux, causing part of the flux to be escaped into the air.
- Steel grade – the best choice is high-permeability steel. Cast iron may generate lower lifting capacity.
- Surface structure – the more even the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Thermal factor – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was measured using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Powerful field
Exercise caution. Neodymium magnets attract from a long distance and snap with huge force, often faster than you can move away.
Shattering risk
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.
No play value
Product intended for adults. Tiny parts can be swallowed, leading to serious injuries. Store away from kids and pets.
Nickel allergy
Nickel alert: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, cease handling magnets and wear gloves.
Life threat
Patients with a ICD have to maintain an safe separation from magnets. The magnetism can interfere with the operation of the implant.
Maximum temperature
Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.
Dust explosion hazard
Dust produced during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
GPS and phone interference
Be aware: rare earth magnets produce a field that disrupts precision electronics. Keep a safe distance from your phone, device, and GPS.
Keep away from computers
Very strong magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.
Bone fractures
Big blocks can crush fingers in a fraction of a second. Under no circumstances put your hand betwixt two strong magnets.
