Flux linkage is used because:

  1. it is a vector
  2. the induced e.m.f. in a coil depends on the change in flux through all its turns
  3. it is easier to measure than current
  4. coils have only one turn
Answer

B) the induced e.m.f. in a coil depends on the change in flux through all its turns
