Pros and cons of rare earth magnets.
Strengths
- They do not lose power, even after around 10 years – the reduction in power is only ~1% (based on measurements),
- They maintain their magnetic properties even under external field action,
- Thanks to the elegant finish, the plating of Ni-Cu-Ni, gold, or silver-plated gives an modern appearance,
- Neodymium magnets deliver maximum magnetic induction on a small area, which allows for strong attraction,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of exact creating and adapting to precise needs,
- Wide application in high-tech industry – they are used in hard drives, electric motors, diagnostic systems, also industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We suggest casing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complex forms.
- Possible danger to health – tiny shards of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these devices can complicate diagnosis medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum lifting force for a neodymium magnet – what affects it?
- using a base made of high-permeability steel, acting as a ideal flux conductor
- whose transverse dimension equals approx. 10 mm
- with a surface cleaned and smooth
- under conditions of no distance (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is available only during perpendicular pulling. The resistance to sliding of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Material type – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was measured with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate lowers the load capacity.
Warnings
Danger to the youngest
Always store magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are tragic.
Pinching danger
Big blocks can smash fingers instantly. Never place your hand betwixt two attracting surfaces.
Heat warning
Avoid heat. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Precision electronics
Note: rare earth magnets generate a field that disrupts precision electronics. Maintain a separation from your mobile, device, and GPS.
Magnet fragility
Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Sensitization to coating
Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, cease working with magnets and wear gloves.
Medical interference
Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Mechanical processing
Machining of neodymium magnets carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Safe distance
Avoid bringing magnets close to a purse, laptop, or TV. The magnetism can permanently damage these devices and erase data from cards.
Powerful field
Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.
