Are magnets capable of environmental sustainability?

Magnets are good for this planet’s prosperity. For instance, Flexible magnet sheets are made from 75% recyclable materials, 100% pre-consumer product. Some printable magnet sheet versions are 100% recyclable and can be added back into the manufacturing process to make more magnet sheets. The magnet should never lose their force so fast, so they don’t wear out and are reusable, saving space in landfills. Magnets offer limitless potential for customization at any stage in the process of design. They are available in any shape, size, or color and are good for the environment by recycling and saving resources.

Permanent Magnets – Revolution for Sustainability

Magnetic materials, exclusively permanent magnets, are significant for the performance of renewable energy technologies. The increased dependence on renewable energy sources has accelerated studies in energy-saving technologies around the world. This research focuses on how magnetic materials play an essential role in dynamic renewable energies. Magnetic materials are supposed to be a major key in driving the new industrial revolution.

Application of permanent magnet for sustainability

The technology development focus has shifted towards renewable or recycled as the new energy source frontiers in current years. Magnetic materials play a crucial role in devices’ efficient performance in various applications such as power generation, air-conditioning, transportation, and telecommunications. The drive to improve electricity transmission efficiency and replace oil-based fuels with innovative electric motors in transportation has motivated researchers to focus on magnetic material technologies.

The exceeding demand for electricity in the past few decades will require a heavy investment in energy-proficient power generation in some instances; smaller sized lightweight devices are favorite, such as in transportation and wind power. The need for maximized power volume at various operating temperatures has shown a path to developing rare-earth permanent magnet procedures to improve electromotor temperature stability.

NdFeB magnet for energy storage

Another approach is developing textured nano-composites, which may lead to the next generation of permanent magnets. It is the prime reality that the world is moving towards cleaner and more efficient energy sources. It is expected that a new industrial revolt will be ignited by such need, which will carry online specialized industries to meet the energy demand. At present, the choice of a permanent magnetic material for an application is mainly based on a balanced consideration of price and performance. The goal for lightweight designs of devices and portable sizes has enabled NdFeB to be the magnet of choice for higher-end applications.

The powerful factor in demand for permanent magnets is high-energy electronic products such as iPods, DVDs, sensors, cameras, and, most important, cell phones. High-energy magnets enable these devices’ efficiency, which significantly reduces the electrical power requirement of those devices. There are many other applications where NdFeB has been used vastly, like electric vehicles, electric-assisted speakers, windmill generators, magnetic separation units, electric bicycles, and magnetic resonance imaging (MRI).

NdFeB magnets development emanates the need to obtain effective magnetic energy products utilized in many technologies such as clean energy technologies for sustainability are wind turbine generators and hybrid regenerative motors, transportation components, and consumer products.

Permanent magnetic play a pivotal role in modern society owing to their unique ability to perform several tasks as follows:

    1. It aids in converting mechanical energy to electrical energy.
    2. It is suitable for transmitting and distributing electric power effectively.
    3. Magnets facilitate microwave communications.

Besides the benefits, the major problem resides in the materials from which permanent magnets are made. Most of the permanent magnets used in renewable energy technologies are constructed from rare-earth metal alloys. These materials have byproducts that are harmful to the environment and thus contradict the aim of sustainability. Further, these are costly for their availability, which cannot fulfill the purpose of economic sustainability.

However, eliminating rare-earth metals with a more sustainable one is the solution to such an issue on which several research projects are going.

Scientists are studying the usability of different readily accessible metals as the alternative to rare-earth metals. By this approach, they are trying to resolve the drawbacks we have with generating clean energy technologies.

Some of the on-going studies focus on widely available as well as easily accessible materials to reduce the extraction cost.

Conclusion:

There is no doubt that scientists and engineers worldwide focus on reducing the reliance on hydrocarbon energy sources in favor of renewable energy.

Without using clean energy technologies in favor of reducing the carbon footprints and their impacts, we can’t save our earth from being destroyed. Permanent magnet finds use in many renewable energy technologies and is key to its success.

Furthermore, our sustainable development goals will be fulfilled by creating clean energy technologies more sustainably. It refers to not only environmental sustainability but also social and economic sustainability. Considering rare-earth metals for the future of green technology, we can reach our ecological goal.

However, as these materials are referred to as “critical raw materials” due to the difficulty in locating and extracting, these are not cost-effective. That’s the only drawback of using rare-earth-based permanent magnets, which can be resolved after finding the potential alternative to fulfill sustainability in every possible way.
