Consists of changing electric and magnetic fields and can travel through empty space and matter?
an Electromagnetic Wave
Consists of changing electric and magnetic fields and can travel through empty space or matter?
An electromagnetic wave.An electromagnetic wave.An electromagnetic wave.An electromagnetic wave.
Can moving electrons through a magnetic field can produce an electric current?
Electrons moving is an electric current. An electric current moving at an angle to a magnetic field will produce a Force.
What flows through a circuit and causes a magnetic field?
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
Which is true electric current running along a wire can be used to produce magnetic force or moving electrons through a magnetic field can produce an electric current?
They're both true, but I'm not comfortable with the way they're stated. I would have said: -- Electric current through a wire produces magnetic force. -- Moving electrons constitute an electric current, whether or not they're moing througha magnetic field.
What do electromagnetic consist of?
they consists of vibrating electric and magnetic fields that move through space at the speed of light.

Why steel becomes a permanent magnet after electric current is passed through it?
Electric current is magnetic so when electric current pass through steel , steel will have the electric power and may be magnetic for awhile
Working principle of ammeter?
An ammeter consists of a coil with very low resistance. when electric current flows through the coil, the coil induces a magnetic field which turns the needle.

An electromagnetic wave.An electromagnetic wave.An electromagnetic wave.An electromagnetic wave.
Does an electric current traveling through a wire generate a magnetic field?
Yes, an electric current traveling through a wire generates a magnetic field. There is no way that it cannot do this.
How do magnets magnetic fields electric currents and metals connect?
Well when an electric current flows through a conductor a magnetic field is produced. And a changing magnetic flux through a conductor produces a current in the conductor.
Can moving electrons through a magnetic field can produce an electric current?
Electrons moving is an electric current. An electric current moving at an angle to a magnetic field will produce a Force.
When a electric current flows through a wire it creates a?
When an electrical current flows through a wire it creates what is called an Electro Magnetic Field.A magnetic field is create when an electric current flows through a wire.
How light waves travell through no media?
James Clerk[sic] Maxwell was able to show that an electric field vibrating at a specific frequency would result in a magnetic field vibrating at exactly that same frequency, and that the latter magnetic field would result in an electric field vibrating at the same frequency -- ad infinitem. He was also able to show that this continual vibration would travel away from its starting point at the speed of light -- thus showing that light, at its basic nature, is a vibrating EM field. Experiments showed that pretty much all predictions based on Maxwell's Equations did, indeed, occur -- such as this EM field travelling without any media needed.
How is light self-propagating?
Light is self-propagating because it consists of electromagnetic waves that do not need a medium to travel through. When an electric field changes, it generates a magnetic field, which in turn generates an electric field and so on, creating a self-sustaining wave that can travel through empty space.
Why cant sound waves travel through empty space?
Sound waves are mechanical waves, NOT electromagnetic waves. Mechanical waves need a substance to pass through, that is, they need some sort of surface to vibrate against to send compression waves through to the surrounding air. Electromagnetic waves however may travel through empty space as they have no need for a surface, instead, they need only electric and magnetic fields that are present in empty space to pass through. (vibrating electric fields will, in turn, vibrate the magnetic field, which will then trigger a nearby electric field to vibrate, which will make another magnetic field to vibrate, and this is how electromagnetic waves may travel through empty space, but mechanical waves may not)
