Strengths as well as weaknesses of rare earth magnets.
Strengths
- Their strength remains stable, and after around 10 years it drops only by ~1% (according to research),
- Neodymium magnets are characterized by remarkably resistant to demagnetization caused by magnetic disturbances,
- The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- Neodymium magnets ensure maximum magnetic induction on a contact point, which increases force concentration,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
- Possibility of exact machining as well as optimizing to specific requirements,
- Universal use in innovative solutions – they serve a role in hard drives, electric motors, precision medical tools, also multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Limited ability of making threads in the magnet and complex forms - recommended is casing - magnet mounting.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these devices are able to complicate diagnosis medical when they are in the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum lifting force for a neodymium magnet – what it depends on?
- with the contact of a yoke made of special test steel, guaranteeing maximum field concentration
- possessing a thickness of min. 10 mm to avoid saturation
- characterized by even structure
- with total lack of distance (no coatings)
- for force applied at a right angle (in the magnet axis)
- at conditions approx. 20°C
Lifting capacity in real conditions – factors
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Material type – ideal substrate is high-permeability steel. Stainless steels may attract less.
- Surface finish – ideal contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Adults only
Absolutely store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets clamping inside the body are tragic.
Electronic devices
Equipment safety: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
Warning for allergy sufferers
Studies show that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, refrain from direct skin contact and opt for versions in plastic housing.
Finger safety
Large magnets can crush fingers in a fraction of a second. Do not put your hand between two strong magnets.
Fire risk
Powder created during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Respect the power
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Risk of cracking
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Operating temperature
Keep cool. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
Warning for heart patients
For implant holders: Strong magnetic fields disrupt electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.
GPS Danger
Remember: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your mobile, tablet, and navigation systems.
