Electric to Magnetic Circuit Quantities

Basic Circuits

General Strategy

  • Write down equivalent circuit
  • Find l’s of circuit (you can combine series lengths into one l and reluctance to save on computation)
  • Find the reluctance (R) of each l
  • Find R_tot (total reluctance)
  • Use R_tot, N, and I to find magnetic flux
  • Find B if needed

Sample Definitions for l

here some sample definitions for l are given which were used to find reluctance
