Applications: Electric motors, Magnetic levitation, Magnetic storage devices

Electric motors convert electrical energy into mechanical movement by using magnetic fields to produce rotation, powering devices like fans and electric vehicles. Magnetic levitation (maglev) uses magnetic forces to lift and propel objects, enabling high-speed trains that glide smoothly with minimal friction. Magnetic storage devices, such as hard drives, store data by magnetizing tiny regions on a disk surface; reading or writing data involves detecting or changing these magnetic states. All three applications leverage magnetic fields and principles of electromagnetism to perform useful functions efficiently and with precision across various technologies.
