1. Which statement about the nature of electric and magnetic fields is the most accurate? A)Fields can only ever be "electric" or "magnetic", regardless of reference frame. B)Whether a field is seen as "electric" or "magnetic" depends on the motion of the reference frame relative to the sources of the field. C)"Electric" and "magnetic" fields are entirely unrelated.
