Electromagnetic transducers are devices that convert energy from one form to another using electromagnetic principles. They typically transform electrical energy into mechanical energy or vice versa. Common examples include microphones, which convert sound waves into electrical signals, and speakers, which do the opposite by turning electrical signals back into sound. These transducers operate based on the interaction between electric currents and magnetic fields. When an electric current flows through a coil of wire in a magnetic field, it generates a force that can produce movement. This principle is fundamental in various applications, including electric motors and generators.
