Can an electric current generate an electromagnetic wave?
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.
The transfer of thermal energy by electromagnetic wave?
Electric current
What changes a sound wave into an electric current?
Sound waves are longitudinal waves. These would vibrate a diaphragm which has been attached with a coil kept in a magnetic field. As the coil vibrates then current is induced. This is how sound wave gets changed into electric current.
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.
A vibrating electric charge produce what kind of wave?
electric wave

Why is the electric current you receive at your house is called alternating current?
The voltage and current are delivered in a sine wave that goes positive and then negative at 60 cycles per second. Google sine wave to see what a sine wave looks like.

Does earphones change electric current to sound wave?
Yes, ear buds and headphones are miniature speakers.
A vibrating electric charge produce what kind of wave?
electric wave
Can a sound wave produce a magnetic field?
sound wave cannot produce magnetic field because magnetic field is created due to flow of electric currents sound is a mechanical wave, sound is produced due to vibration in a medium so sound wave cannot create electric current or magnetic field
Can electromagnetic wave deflect by electric or magnetic field?
No. An electromagnetic wave IS electric and magnetic fields.
What is the continuous flow of electric charges through a material?
Yes, an electric current is the flow of charged particles.
What is the direction of flow of electric current in an electric current?
DC current
What type of wave is 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.
