  4. Coefficient of Coupling • k is known as the coefficient of coupling • value lies between 0 and 1 • k = 0 when two coils have no common flux • Φ12 = Φ21 = 0 • P12 = 0 • 1/k2 = ∞ • M = 0 ECE 201 Circuit Theory 1

  5. Coefficient of Coupling continued • k = 1 • Φ11 and Φ22 are both = 0 • all flux linking coil1 links coil 2 • can’t be • using magnetic materials in the space allows conditions for k to approach 1 ECE 201 Circuit Theory 1
