Strengths and weaknesses of rare earth magnets.
Benefits
- Their power is durable, and after around 10 years it drops only by ~1% (according to research),
- They possess excellent resistance to magnetism drop when exposed to external fields,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- They feature high magnetic induction at the operating surface, which increases their power,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the option of accurate forming and adaptation to unique projects, magnetic components can be manufactured in a variety of shapes and sizes, which makes them more universal,
- Huge importance in advanced technology sectors – they are commonly used in hard drives, electromotive mechanisms, medical devices, also technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and 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.
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing nuts and complex shapes in magnets, we propose using a housing - magnetic mechanism.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. Furthermore, tiny parts of these products are able to complicate diagnosis medical when they are in the body.
- With mass production the cost of neodymium magnets can be a barrier,
Lifting parameters
Magnetic strength at its maximum – what affects it?
- using a plate made of mild steel, acting as a ideal flux conductor
- possessing a massiveness of min. 10 mm to avoid saturation
- with an ideally smooth touching surface
- with zero gap (no coatings)
- for force acting at a right angle (in the magnet axis)
- in stable room temperature
Lifting capacity in practice – influencing factors
- Distance (betwixt the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Steel thickness – too thin plate does not close the flux, causing part of the power to be lost to the other side.
- Material composition – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Plate texture – ground elements ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was assessed by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet and the plate reduces the load capacity.
Safe handling of NdFeB magnets
Maximum temperature
Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Pinching danger
Risk of injury: The pulling power is so immense that it can result in hematomas, pinching, and broken bones. Use thick gloves.
Shattering risk
Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Fire warning
Dust produced during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Health Danger
Patients with a ICD have to keep an absolute distance from magnets. The magnetism can interfere with the functioning of the implant.
Danger to the youngest
Adult use only. Tiny parts can be swallowed, causing serious injuries. Store out of reach of children and animals.
Warning for allergy sufferers
Some people suffer from a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact can result in dermatitis. We recommend use safety gloves.
Do not underestimate power
Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Electronic devices
Do not bring magnets close to a purse, laptop, or TV. The magnetic field can destroy these devices and erase data from cards.
Magnetic interference
Be aware: rare earth magnets generate a field that confuses precision electronics. Maintain a safe distance from your mobile, device, and GPS.
