v t e Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. The electric current produces a magnetic field around the conductor. The magnetic field strength depends on the magnitude of the electric current, and follows any changes in the magnitude of the current. Step 2: Test the Connectors. A coaxial cable doesn’t have polarity. Touch the probe leads on the two connectors of the coax cable. If the multimeter beeps and reads less than 1 ohm, your coaxial cable has continuity. If the reading exceeds one ohm, your connectors are faulty. Video | TheSmokinApe.Inductance per length in a coaxial cable.
