Strengths and weaknesses of rare earth magnets.
Benefits
- They retain full power for around ten years – the loss is just ~1% (in theory),
- They maintain their magnetic properties even under strong external field,
- Thanks to the glossy finish, the plating of nickel, gold-plated, or silver-plated gives an visually attractive appearance,
- Neodymium magnets create maximum magnetic induction on a small surface, which ensures high operational effectiveness,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in forming and the capacity to adapt to complex applications,
- Wide application in electronics industry – they are commonly used in mass storage devices, electric drive systems, medical devices, also other advanced devices.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend 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 power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing threads and complicated forms in magnets, we propose using casing - magnetic mechanism.
- Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, tiny parts of these magnets can complicate diagnosis medical in case of swallowing.
- With mass production the cost of neodymium magnets can be a barrier,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what it depends on?
- using a plate made of low-carbon steel, acting as a circuit closing element
- whose transverse dimension reaches at least 10 mm
- with an polished contact surface
- under conditions of no distance (metal-to-metal)
- for force applied at a right angle (in the magnet axis)
- at ambient temperature room level
Determinants of practical lifting force of a magnet
- Clearance – the presence of any layer (paint, tape, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of nominal force).
- Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be wasted into the air.
- Material type – the best choice is high-permeability steel. Cast iron may attract less.
- Surface structure – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet and the plate decreases the load capacity.
Warnings
Sensitization to coating
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, cease handling magnets and wear gloves.
Crushing risk
Watch your fingers. Two powerful magnets will snap together immediately with a force of massive weight, crushing anything in their path. Be careful!
Respect the power
Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Medical implants
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Shattering risk
Protect your eyes. Magnets can fracture upon violent connection, launching shards into the air. Wear goggles.
Magnetic interference
An intense magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Maintain magnets near a device to avoid breaking the sensors.
Fire warning
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Protect data
Do not bring magnets close to a purse, computer, or TV. The magnetic field can destroy these devices and erase data from cards.
Product not for children
Adult use only. Tiny parts can be swallowed, causing severe trauma. Store away from children and animals.
Heat sensitivity
Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
