[QUOTE="Einstein, post: 157315, member: 288"] I do see that you corrected your statement about current being used up. I wasn't trying to pick on you. But I still don't think you're quite understanding that no current flows through an antenna during radio wave emission. The antenna is always connected as if it was half of a capacitor. Ideally the antenna should have no capacitance. But it does because the antenna has surface area. Since no current flows through the antenna, no magnetic field is present during emission of the radio wave. So only an electric wave is transmitted. But I did find a link to a high frequency current probe you could use to verify no AC magnetic wave is present in your transmitting antenna.

Anyway you got me thinking how a magnetic wave antenna could be made. I think a normal radio transmitter could be used with minimal modification. Any current carrying conductor will emit a magnetic field. So it occurred to me that grounding the end of the radio antenna would allow current to run through.
