Advantages as well as disadvantages of neodymium magnets.
Pros
- They retain magnetic properties for nearly ten years – the loss is just ~1% (in theory),
- They do not lose their magnetic properties even under strong external field,
- Thanks to the elegant finish, the layer of nickel, gold-plated, or silver gives an modern appearance,
- Magnetic induction on the working layer of the magnet turns out to be very high,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to versatility in forming and the ability to adapt to unusual requirements,
- Versatile presence in electronics industry – they serve a role in HDD drives, electric motors, medical devices, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in compact constructions
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in force. 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
- 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 suggest casing - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these magnets can disrupt the diagnostic process 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 holding power of the magnet – what contributes to it?
- on a block made of structural steel, perfectly concentrating the magnetic flux
- possessing a thickness of at least 10 mm to avoid saturation
- characterized by even structure
- with total lack of distance (no paint)
- under perpendicular force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Distance (betwixt the magnet and the metal), as even a very small distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Direction of force – maximum parameter is reached only during pulling at a 90° angle. The shear force of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick plate does not close the flux, causing part of the power to be wasted to the other side.
- Material type – ideal substrate is pure iron steel. Stainless steels may attract less.
- Base smoothness – the smoother and more polished the surface, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet and the plate lowers the lifting capacity.
Safe handling of neodymium magnets
Heat sensitivity
Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.
Keep away from computers
Very strong magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Nickel coating and allergies
Studies show that the nickel plating (the usual finish) is a common allergen. If you have an allergy, prevent touching magnets with bare hands or select encased magnets.
Product not for children
NdFeB magnets are not intended for children. Eating a few magnets may result in them attracting across intestines, which poses a direct threat to life and necessitates immediate surgery.
Machining danger
Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.
Threat to navigation
An intense magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Keep magnets near a device to avoid damaging the sensors.
Warning for heart patients
Patients with a ICD must maintain an safe separation from magnets. The magnetism can disrupt the functioning of the life-saving device.
Powerful field
Handle magnets with awareness. Their immense force can surprise even experienced users. Be vigilant and do not underestimate their power.
Crushing force
Big blocks can crush fingers in a fraction of a second. Under no circumstances place your hand betwixt two strong magnets.
Material brittleness
Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
