What is the significance of self-inductance in a coaxial cable and how does it affect the transmission of signals through the cable?

Self-inductance in a coaxial cable is significant because it creates a magnetic field around the cable when current flows through it. This magnetic field can interfere with the transmission of signals by causing signal loss or distortion. To minimize this effect, coaxial cables are designed with specific spacing and materials to reduce self-inductance and improve signal transmission quality.
