I beleive what you are referring to is a modulated signal which can be either amplitude, frequency or phase modulation. As with radio signals carrying information: AM, FM or PM.

Does a moving magnetic field produce an electric current?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
Can an electric current exert a force on a magnet?
In a conductor - only if the field is moving, thus changing.
What is the classical explanation of a dc electric current in a metallic wave?
A changing magnetic field always produces an electric field, and conversely, a changing electric field always produces a magnetic field. This interaction of electric and magnetic forces gives rise to a condition in space known as an electromagnetic field.
What causes a electric current in a electric circuit?
Voltage causes current to flow in an electric circuit.
What does the electric current have?
In metal conductors, electric current is the flow of electrons.
What does an electric current Carry?
Electric current carries electric charge. Actually to say it in the right sense, we have to say that electric current is the rate of flow of electric charges
The current that flows in an electric circuit carries what?
Current Carries Negatively charged electrons.
A carries electric current easily while an does not?
a insulator
What do you call a material that carries an electric current?
A Conductor.
How electric current have magnetic effect?
The magnetic force acts only on moving electric charges; A constant electric current produces an unchanging magnetic field and a changing electric current produces a changing magnetic field.
A substance that carries an electric current when dissolved in water is called?
Electrolyte
A moving magnet produces an electric current is this true?
A changing magnetic field produces an electric current, so yes. This is true.
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.
Is an electric voltage a varying electric current that reprsents information?
false
Is electric current stored anywhere?
Electric current is the movement of charge around a circuit and so cannot really be stored, however, the energy which it carries is stored in most things.
What Changing a magnetic field can produce an electric current?
its a fact which was observed by faraday
What happens to copper wire because of the moving magnet?
The copper wire carries an electric current.
