J. H. Ross, Department of Physics, Texas A&M University Inductance (ch. 30) Φ m = I L defines L = inductance m = “self” flux due to I in the inductor so, ε = L ( dI dt ) 1 = I 2 M defines M = mutual inductance 2 = M ( dI 1 dt ) Units for M or L : 1 Henry (1 H) = 1 T m 2 /A (or 1 s) Long solenoid result: L o n 2 Al or μ o N 2 RL transients: = L dI dt back emf (opposes current increase)
