How significant are hysteresis losses in iron wires with RF currents?


I understand that iron isn't a great choice of conductor for RF currents, as a wire dipole antenna for example. I understand there are several reasons, but I'm wondering specifically about one: hysteresis losses. How significant are hysteresis losses when an iron wire is a conductor, not part of a magnetic circuit? Can they be calculated? Are there any empirical data?

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
