In textbooks on electromagnetism the H field is expressed in terms of the B field and then the H field is found for various things like toroidal cores and antennas. What exactly is the H field? Is it directly measurable? Does it actually exist? In textbooks the H field is found for a toroidal core with an air gap. The mathematical expression for the H field contains mu but the H field is supposed to be the component (of what?) that is independent of the material? I understand what the B field is but exactly what the H field is is a mystery to me. Can someone help?
