Got it, thanks very much. Usually, for me, Wikipedia is not too easy to follow on involved scientific matters which is why I did not look there for an answer, but in this case it was easy to understand. I think my understanding got thrown off because some explanatory information I read...

I believe that if a put current through a coil of wire and if I have unlimited power to force through that current and if the coil can accept unlimited power without being degraded, I could produce a magnetic field in a vacuum of unlimited strength-is that correct? But supposedly if I applied...

Hi, Thanks for your post. Yes, I do need a further clarification regarding part of the definition of H that I've seen. I've seen H defined in part as the external field imposed upon a material by an external source and that H field in turn induces a magnetization field inside the material M...

Here is an even more profound question. If an H field is supposed to be due to current external to the material, then how can an H field exist inside a magnet that is floating in a vacuum with no external current source anywhere near it? Shouldn't H be zero since there is no source of a...

I am also confused by B and H. In some texts, they show B pointing one direction inside a magnet but H pointing the opposite direction. If B = uH, then how can it ever be true that the B vector can point in any direction other than the direction of the H vector inside a material? What...
