EE 205 Dr. A. Zidouri-3-Self Inductance •A magnetic field consists of force surrounding the current carrying conductor. •The voltage induced in the conductor is proportional to the number of lines that collapse into or cut the conductor. Faraday’s Law isdvdtλ=λis the flux linkage and is measured in Wb –turns
