Neodymium Arc Magnets: Tips of Online Shopping

Neodymium magnets can be used in a variety of applications. This is because they come in many different shapes. Neodymium arc magnets are good examples of commonly sold shapes. They have several uses in varied industries. An arc is just a small segment of a professionally produced NdFeB magnet. It can be customized to match the customer’s specifications. So it is wise to purchase an arc segment after determining the correct size for a particular project. To shop quickly and conveniently, a customer can shop online. There are numerous stores that target USA customers. So make sure you pick a reputable and licensed seller of a variety of magnets.

A neodymium arc magnet is made via a complex technique that entails grinding and wire cutting. It is therefore necessary to look for the following characteristics before ordering arc segments.

·         Outer radius/diameter

·         Inner radius/diameter

·         Circumference of the round edge

·         Thickness

·         Length

·         Angle

There are many ways to use neodymium arc magnets. When determining how to use them, one must focus on their project requirements. Does it require small, medium or large arc segments? All of them are available on popular internet shops. In general these segments can be used to manufacture the following.

·         Auto motors. Whether one wants a neo arc magnet for the window rolling motor or starter they can all be ordered directly from an internet store.

·         Electric tools

·         Medical and health care devices, such as the MRI.

·         DC motors

·         Dynamo motor

·         Rotors

It is essential to note that arc magnets made from Neodymium, Iron and Boron are not unique than other magnet shapes. All of them have similar properties with regard to factors such as coercivity, Curie temperature, resistance to corrosion and energy product. But it is vital to note that neodymium arc magnets can be weaker or stronger depending on the N-rating or grade. For instance, an arc rated N38 is automatically weaker than an arc rated N55. A customer should be aware of the neodymium N-rating scale, which begins from N35 to N55. This will help them order neodymium arc segments that can assist them to finish their projects.

With regard to corrosion, small, medium and large-sized segments will be affected. A good vendor will automatically sell coated or plated magnets. They will display their products based on the kind of coating or plating they boast. A triple layer of nickel, copper and nickel is a very common plating method. There are also other materials used for protecting Neo magnets from rust, including zinc, copper, gold, silver, tin and epoxy among others. It is advisable to reflect on the environment that new arc magnets would be exposed to prior to buying them. This is because even a plated or coated magnet may not perform well in some surroundings. If guidance is required, a customer should contact the manufacturer or seller of their neodymium arc magnets.

Neodymium Bar Magnets: Orientation of Magnetization

As technology advances permanent magnets made of rare-earth magnets will remain in high demand. Depending on one’s project, a neodymium magnet of a particular shape can be found. For instance, neodymium bar magnets can be applied to projects that have straight edges. A bar magnet is a rectangular-shaped thing. It is a block from which many other shapes can be cut out. Bar-shaped neo magnets have varied sizes. Each size is compatible with a given application. Thus it is essential to know where to apply a neodymium bar magnet of a particular size. If a customer is not sure of the correct size or dimensions for their application, they should ask the manufacturer for assistance.

An experienced magnet manufacturer would obviously know which magnet fits where. Size is often described in terms of thickness, diameter, width and length among other factors. As far as neodymium bar magnets are concerned, size is defined using length x width x thickness. Thickness is normally found along the axis of magnetization and it is often the smallest dimension. When one is looking to buy a longer magnet, they will hardly find a type that is magnetized through thickness. In most cases long bar NdFeB magnets are magnetized via the width or length. So far one can realize that bar magnets can either be short or long. There is also a very necessary factor to consider. This is orientation, is defined as the direction of magnetization.

Usually identified during the die-pressing stage, orientation can differ in two ways. Some magnets lack orientation, meaning that they can be magnetized in all directions or any direction. These are known as isotropic. The types that have orientation, meaning that they can be magnetized in only one direction are called anisotropic. These are commonly preferred because of their strong magnetic field. When looking for neodymium bar magnets one should be keen on anisotropic and isotropic detail. It should be communicated clearly to the customer to avoid confusion. Some products on sale may be un-magnetized anisotropic or isotropic options. This important detail should also be clearly communicated by the vendor. The direction of magnetization can be symbolized in two ways: drawings or written words.

They usually write M or <M>. It is typically written next to the dimension that is parallel to the direction of magnetization. And they will also indicate whether the magnet has been magnetized through its thickness, diameter or axially. When a drawing is used to symbolize orientation, two labeled arrows are used pointing opposite directions and separated by letter M. The arrows are usually parallel to the direction of orientation or magnetization. Polarity is also indicated to help customers get their desired neodymium bar magnets. When polarity is unknown, a customer may pick the wrong choice for their function or project which will waste time and money. Polarity indication is particularly beneficial to those who wish to use non-symmetric NIB magnets.

Japan’s Search For Alternative Energy Is Almost Over

Almost entirely dependent on nuclear power just two years ago, Japan is making more investment into renewable energy.  The Japanese government is paying 22 billion yen, or $226 million, to construct the first three floating wind turbines 12 miles away from Fukushima.  By 2020 Japan plans to place 140 wind turbines to produce over 1 gigawatt of electricity.  That is equivalent to the power generated by a nuclear reactor.

These turbines are unlike any other as they float on giant platforms anchored to the seabed.  This new innovation expands potential locations for offshore wind farms, which are traditionally fixed into the seabed.  This limits their location to water depths of around 50 feet or less- close enough to shore that they are still visible.

The researchers estimate their floater-mounted turbines could work in water depths ranging from about 100 to 650 feet. This means that they could be placed about 30 to 100 miles out at sea. Because winds are stronger farther offshore, the floating windmills could also generate more energy—5.0 megawatts (MW), compared to 1.5 MW for onshore units and 3.5 MW for conventional offshore setups.  Like the offshore windmills currently in use, the floating turbines would use undersea cables to shuttle the electricity to land.

Harnessing wind in deeper waters off Japan could generate as much as 1,570 gigawatts of electricity, roughly eight times the current capacity of all of Japan’s power companies combined, according to computer simulations based on historical weather data by researchers at Tokyo University, one of the project’s main participants.

However the farther from the coast they place these floating wind farms, the more expensive it becomes to build them and transmit the power back to Japan.  It could become a cost-plus benefit analysis in which you weigh the benefits of the electricity versus the cost to build and maintain the infrastructure.
