1. Can a solenoid connected to alternating current generator be used as transmitter of electromagnetic radiation?
2. Can a solenoid be used as a receiver of electromagnetic waves?
I think point 2. is possible, since alternating magnetic field will induce voltage in the loops of solenoid.
An alternating current in a solenoid would generate an oscillation of magnetic dipole moment. I guess this would emit electromagnetic radiation based on the similarity between electric and magnetic field (since an oscillating electric dipole moment does emit electromagnetic radiation).
Are this considerations correct? Also why transmitters/receivers (for example radio antennas) never have the form of a solenoid?
