How can a magnet be used to create an electric current?
An electrical current will flow in a conductor, when a magnet is moved next to a conductor - or when the conductor is moved next to the magnet.
Is not a permanent magnet?
An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.
What is a magnet made by electric current?
An electromagnet.
How can a magnet be used to create an electric current using the words magnetic field attract repel magnetic poles?
A magnet cannot use words to create an electric current. A moving magnet will induce electric current in adjacent conductors. This is usually described in terms of the rate that magnetic flux lines connecting the opposite poles of the magnet "cut" the conductors. The more flux lines cutting the conductors per second, the more current induced.
Will there be a induced current if the magnet remains at rest?
No, a stationary magnet will not induce a current in a nearby conductor. Movement or change in magnetic field is required to induce an electric current in a conductor through electromagnetic induction.
What is a magnet that is creadted from electric current through a wire?
Electro-Magnet
What controls the strength of a magnet made with electric current?
The strength of a magnet(electromagnet) made by flowing electric current through a conducting coil depends on magnitude of current. . .
How does an electric current make a magnet?
the electric current is generated by the electric field. thus by the left hand rule when current is passed through a conductor a magnetic field is generated around it so that it is a similar act of a magnet. thus it seems to be a magnet.
What happens to the electric current when you stop moving the magnet inside the coil?
It is quickly dissipated into heat by what-ever minor resistances exist.
What is a magnet created when electric current flows through a coil of wire?
A magnet created when electric current flows through a coil of wire is called an electromagnet.
A magnet can generate an electric current in a wire if the magnet is close enough to the wire and if the magnet is also?
strong
What is the definition of eletro magnet?
A magnet that becomes energised when an electric current is passed through it.
How can a magnet be used to create an electric current?
An electrical current will flow in a conductor, when a magnet is moved next to a conductor - or when the conductor is moved next to the magnet.
When does a magnet induce an electric current in a wire coil?
A magnet induces an electric current in a wire coil when there is a relative motion between the magnet and the coil, which generates a changing magnetic field. This changing magnetic field induces an electromotive force, leading to the flow of an electric current in the wire coil.
Will there be an induces electric current if the magnet remains at rest?
No, there will be no induced electric current if the magnet remains at rest relative to the conductor. Movement or a change in magnetic field is required to induce an electric current in a nearby conductor through electromagnetic induction.
Is not a permanent magnet?
An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.
What type of magnet has an iron core and electric current?
an electromagnet
