Harnessing Magnetism: Cutting-Edge Applications and Scientific Advancements
Main Article Content
Abstract
Magnetism is a key topic in the field of physics. It is also used in a variety of other applications to make useful and earth-friendly technologies. In this article, you will learn about the fundamentals of magnetism (based on the movement and spin of electrons), the different kinds of magnetism (ferromagnetism, diamagnetism, and superparamagnetism), and how we use them for various things. A number of recent advances, such as spintronics, magnetic skyrmions, magneto-ionics, and two-dimensional (2D) magnetic materials, are highlighted to demonstrate how the ability to manipulate magnetism at the nanometer scale underpins advances in data storage, quantum computers, and medical applications. Applications in health care, energy, information, and communication as well as technology for environmental protection are discussed (for example, magnetic resonance imaging, magnetic nanoparticles, magnetic levitation, magnetic cooling). There are also new trends such AI-designed magnetic tools, nature-mimicking magnetic systems and environmentally friendly magnets that don’t contain rare earth metals. Relevant topics are also addressed, such as pollution, health hazards, the difficulty of material recovery and high costs. This review briefly retells the story of the magnet and summarizes recent research involving magnets, while emphasizing the demand and philomovision that more investigation may be encouraged to be conducted in the future.
