This paper will demonstrate how maglev trains work with electromagnets. We will provide information about the history of early electromagnets. We will also provide information on the locomotion process, which is done through the generation of an electromagnet field by the rotor around the stationary magnet causing the torque from the magnet to pull or push it [1]. The paper will describe how each part of the electromagnet works. There are projects that we will discuss that helped further the development of electromagnets. We’ll inform the reader of current working models around the world. As well as describing the train and how it functions and various examples of the types of systems. We will also give information about the ethics behind the train. New technologies in today’s world must not only perform in the short term but also into the foreseeable future. Sustainability is one of the most important factors to be considered before adopting any type of new technology, and Maglev trains are no exception. Luckily for maglevs the way they work leads to high sustainability. This paper will talk about sustainably as well. Through this paper one will gather greater knowledge about electromagnets and maglev trains
