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 is d v dt λ = is the flux linkage and is measured in Wb –turns

EE 205 Dr. A. Zidouri - 4 - Self Inductance (Cont) The flux linkage λ is the product of magnetic field ( Φ ) measured in (Wb) and the number of turns linked by the field (N). N λ= Φ The magnetic flux Φ is related to the magnitude of the coil current by the relationship: where p is the permeance of the space occupied by the flux N is the number of turns i is the current pNi Φ =
