No. Only those carrying AC. Those carrying DC have a constant magnetic field around them and emit no waves.
yes
No. Current flow creates electromagnetic fields in space. Electromagnetic fields, in turn, can create current flow in conductors. The electric fields do not directly create magnetic fields, nor do magnetic fields directly create electric fields.
Ultrasonic waves are high frequency sonic waves. They're sound, which is mechanical energy. Electromagnetic waves are waves of electromagnetic energy, like radio waves or light. Mechanical energy is different from electromagnetic energy, hence the reason for ultrasonic waves not taking the form of electromagnetic waves.
because sound waves are not a electromagnetic waves because they need a medium for travel....hence electromagnetic spectrum is based on the electromagnetic waves ..like radio waves , micro waves , etc....
electromagnetic waves are longitudinal (like a slinky).
Sound waves aren't an electromagnetic wave. So aren't seismic waves. So aren't waves in the ocean, in your hair, or waves bye-bye.
is a flow of electromagnetic waves that have a potential
Current flows through any conductor when electromagnetic waves fly past it. That's how a radio antenna works.

Electromagnetic waves
According to Faraday's law: "When current is passed through a conductor, an EM field is produced surrounding it." As an antenna contains one or more conductors, the terminals of which are connected to some voltage, when this voltage at the terminals is applied, it produces/induces the alternating current which radiates the elements in the electromagnetic field. (Transmission) The reverse of this occurs in reception; where the electromagnetic field from another source induces an alternating current in the antenna, and a corresponding voltage at the antenna's terminals.
Radio waves ARE electromagnetic waves.
Electromagnetic waves are transferred by electromagnetic radiation.
first of all electromagnetic waves are energy waves. and we call electromagnetic waves RADIATION.
Examples of mechanical waves are waves in the ocean and sound waves from devices like mouths, trombones, and radios. Electromagnetic waves like sunshine and X-rays are not mechanical waves because matter is not doing the waving.

A transmitter is a set of equipment used to generate and transmit. It transmits electromagnetic waves carrying messages or signals.
