Electromagnetic propulsion is a technology that uses electromagnetic forces to move objects. It typically involves the interaction between electric currents and magnetic fields, allowing for efficient and rapid movement without the need for traditional fuels or engines. This method is often seen in applications like maglev trains, which float above tracks, reducing friction and enabling high speeds. Another example of electromagnetic propulsion is in spacecraft, where it can be used for propulsion systems like ion thrusters. These systems generate thrust by accelerating ions using electric fields, making them suitable for long-duration space missions due to their efficiency and low fuel consumption.
