Electromagnetic systems are technologies that utilize the principles of electromagnetism, which is the interaction between electric fields and magnetic fields. These systems can be found in various applications, such as electric motors, transformers, and wireless communication devices. They rely on the generation and manipulation of electromagnetic waves to function effectively. In an electromagnetic system, electric currents create magnetic fields, and changing magnetic fields can induce electric currents. This principle is fundamental to devices like generators and inductors. Overall, electromagnetic systems play a crucial role in modern technology, enabling efficient energy transfer and communication.
