Strong magnets are deployed in different industries for different purposes, but for the same reasons. Strong magnets impose power in a flexible, predictable, renewable and releasable manner. On heavy kit in military hardware, logistic chains, agriculture, construction and manufacturing these magnets capture, hold, lift, carry and release the whole gamut of goods, gates, gears and gantry.
Suspended over loose run bulk goods, including foodstuffs and pharmaceuticals, quarter ton plate magnets lift and arrest metallic waste. Powerful magnets are embedded in industrial scale doors, gates, trays, hatches, hoses and housings as an intuitive, predictable pull force release and sure and certain, controlled, soft close. Harnessing strong magnets, magnetic couplings, especially in liquid pumps and propeller assemblies, deliver predictable mechanical power through separation barriers. The threshold at which a magnet relinquishes power is often deployed as a torque limiter, protecting motors and gearing assemblies from excessive mechanical force in a jam or crash stop event.
This fail safe function, returning equipment to a risk free state via magnetic agency, is a vital characteristic of magnetic engagement. Winches and hydraulics lean, lock, load and lift using powerful dedicated magnets to regulate and enforce the smooth, supple expression of industrial grade mechanical power. Powerful Rare Earth Neodymium Magnets such as blocks and discs, weigh in at 500 to 1500 grams, yet offer a pull force of up to 295 kilograms. They are often harnessed in water conditioning devices for capturing or crushing heavy metals, mineral salts and rust, turning hard water soft.
AMF magnetics stock a range of especially strong magnets. Our large Neodymium Rare Earth magnets are extremely powerful. Below are some common questions customers have in regards to powerful magnets and our answers.
Which magnets are the strongest?
Neodymium magnets are members of the rare earth family. They are the strongest magnets on the market in terms of holding power and magnetic energy output. This translates into a powerful holding ability that exceeds all other magnetic materials. The mechanical strength of Neodymium products is enhanced by capping the magnet with a steel cover or casing which protects the magnet from being damaged. These capped Neodymium magnets are known as Pot Magnets and are one of the most versatile magnets in the entire product range
Why are Neodymium magnets so strong?
The combination of Boron, Iron and Neodymium elements into a ferromagnetic alloy ( Nd2Fe14B)) results in a material with a tetragonal crystal structure that is able to store a high level of magnetic saturation. This high-level saturation is achieved by aligning the unpaired electrons in the Neodymium atoms which can then project a magnetic field of great intensity and high magnetic energy. This abundance of strength means more magnetic power can be extracted from a magnet with smaller dimensions than previously would have been required. This, in turn, has had a considerable impact on an enormous number of industries and product designs
How to remove strong magnets?
Super-strong magnets and very large magnets can be dangerous!
Protect yourself when handling or using strong or large magnets by wearing gloves and eye protection.
Are strong magnets safe?
Never allow children to play with strong magnets or small magnets. Small magnets especially are a well documented choking hazard for children!
Our tips for handling and working with strong magnets:
- Careless handling and storage of large magnets can result in personal injury.!
- Strong magnets can attract steel or another magnet very quickly and with enough force to damage skin or property.
- The magnetic field of a large magnet can also operate over large distances so it is possible for the magnet to jump across a table with great force.
- Hold magnets with a firm grip when ferrous material or another magnet is present.
- Wrap or cover magnets in protective, impact-resistant material when not in use.
- Place a thick non-ferrous spacer between two magnets so they are easier to separate and use.
- Strong magnets can be removed by slowly and carefully sliding the magnet over a void or right-angled edge of a workbench or countertop.
- Pay attention to adjacent work areas and nearby environments that may contain other magnetic material and surfaces.
- Damaged fingers and other injuries are a common occurrence when strong magnets are handled carelessly or incorrectly!
