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. A*s*i*m*o*v .... The truth is WAY out there! |
