Typically an antenna consists of an arrangement of metallic conductors (elements), electrically connected (often through a transmission line) to the receiver or transmitter. An oscillating current of <answer>electrons</answer> forced through the antenna by a transmitter will create an oscillating magnetic field around the antenna elements, while the charge of the <answer>electrons</answer> also creates an oscillating electric field along the elements. These time-varying fields radiate away from the antenna into space as a moving transverse electromagnetic field wave. Conversely, during reception, the oscillating electric and magnetic fields of an incoming radio wave exert force on the <answer>electrons</answer> in the antenna elements, causing them to move back and forth, creating oscillating currents in the antenna.
What particles are pushed through the antenna by a transmitter?
electrons
