JK Must have been before electrostatics was invented. :-)


Yes, but you are changing the topic into static fields. We were
discussing changing electric fields, not statics but dynamics!


JK But do you agree that it's not impossible for an E field to exist
JK without an H field?


A static E field can exist alone but to detect it requires something
like a field-mill which basically converts it into a changing EM field
that can be readily detected. A simple field-mill is basically a
rapidly spinning antenna. Relativity at work.
