Not a constant electric current but a changing one will generate electromagnetic waves.
First: If you have a lone electron, and it is accelerated in any way, it will send off an electromagnetic wave. This is because a changing electric field generates a magnetic field.
It is also true that changing magnetic field will generate an electric field. This is the reason that if you have an electric current, which is generating a magnetic field, and you change the current you generate an electromagnetic wave. To generate a continuous sinusoidal electromagnetic wave you continuously change the current sinusoidally.
What else can I help you with?
What starts the vibration of the electric and magnetic fields in an electromagnetic wave?
The vibration of the electric and magnetic fields in an electromagnetic wave is initiated by a changing electric current or an accelerating electric charge. When these occur, the varying electric and magnetic fields interact and propagate through space in the form of an electromagnetic wave.
Is it possible to transmit electricity as electromagnetic waves?
Well, when you transmit something as an electromagnetic wave, it is no longer an electric current, since an electromagnetic wave doesn't involve movement of charges. However, you can convert electrical energy into an electromagnetic wave, transfer that, and then convert it back to an electric current at the receiving end.
Is an electric field associated with an electromagnetic wave constant in time?
No, the electric field oscillates in magnitude and direction as it propagates in the electromagnetic wave.
What type of wave is EM radiation?
EM radiation is short for electromagnetic radiation. It is a wave in the electric and magnetic fields.EM radiation is short for electromagnetic radiation. It is a wave in the electric and magnetic fields.EM radiation is short for electromagnetic radiation. It is a wave in the electric and magnetic fields.EM radiation is short for electromagnetic radiation. It is a wave in the electric and magnetic fields.
What is the direction of propagation of an electromagnetic wave?
An electromagnetic wave propagates in a direction perpendicular to both the electric and magnetic fields.

How do the electric and magnetic field of an electromagnetic wave regenerate each other?
In an electromagnetic wave, the changing electric field creates a magnetic field, and the changing magnetic field in turn regenerates the electric field. This process continues as the wave propagates through space, leading to the self-sustaining nature of electromagnetic waves.

Tell how you know if a wave is electromagnetic in character?
A wave is electromagnetic in character if the wave is produced by the acceleration of an electric charge. Another indication is a wave is electromagnetic if it is propagated by the periodic variation of intensities of, usually, perpendicular electric and magnetic fields.
