Answer the following multiple-choice question by giving the correct answer letter in parentheses. Provide CONCISE reasoning for the answer, and make sure to finish the response with "ANSWER: X" where X is one of (A), (B), (C), (D), etc. Question: When a medium is present, we introduce the electric displacement vector and magnetic field strength in addition to the original electric field strength and magnetic induction. Why was magnetic induction not initially called magnetic field strength? Besides historical reasons, can we see any clues from the equations of static magnetic fields? (A) Yes, because the equations of static magnetic fields have the same structure as those of electrostatic fields. (B) Yes, because magnetic induction is a vector source produced by charge density, which is different from the property of electric field strength being a scalar source produced by current density. (C) Yes, because magnetic induction is a scalar source produced by current density, which is different from the property of electric field strength being a vector source produced by charge density. (D) No (E) Yes, because magnetic induction is a vector source produced by current density, which is different from the property of electric field strength being a scalar source produced by charge density. (F) Yes, because the Maxwell's equations for magnetic media without conduction currents and residual magnetism only become equivalent to the Maxwell's equations for dielectric media when magnetic field strength, magnetic induction, and permeability are respectively replaced by electric field strength, electric displacement, and dielectric constant. (G) Yes, because magnetic induction is a scalar source produced by charge density, which is different from the property of electric field strength being a vector source produced by current density.
