Electromagnetic susceptibility refers to the ability of a material to become magnetized when exposed to an external electromagnetic field. It indicates how easily a material can be influenced by electric and magnetic fields. Materials can be classified based on their susceptibility, such as diamagnetic, paramagnetic, and ferromagnetic, each responding differently to electromagnetic forces. The concept is important in various applications, including electronics, where materials with specific susceptibilities are used to design components like inductors and transformers. Understanding electromagnetic susceptibility helps engineers select appropriate materials for devices that rely on electromagnetic interactions, ensuring optimal performance and efficiency.
