What happens when the electric current is reversed on am electromagnet?
When an electric current is reversed in an electromagnet, the magnetic field also reverses.
What is a temporary magnet produced using an electrical current?
An electric current produces a magnetic field.
What does a current carrying coil with an iron core make?
A choke, an electromagnet, an electric motor stator, an electric motor rotor, etc. all depending on details of construction and use that are unstated in the question.
How is an electric magnet made?
An electromagnet can be made simply. When an electric current flows in a wire it creates a magnetic field around the wire. By winding the wire into a coil we can strengthen the magnetic field. Electromagnets are made from coils like this.
How is a simple electromagnet created?
By passing an electric current through any conductor, a magnetic field will be created. Therefore, a simple electromagnet can be created by connecting a power source to a coil of copper wire.
What happens when the electric current is reversed on am electromagnet?
When an electric current is reversed in an electromagnet, the magnetic field also reverses.
When this is turned off the electromagnet is no longer magnetic?
Electric current.
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
What is a temporary magnet produced using an electrical current?
An electric current produces a magnetic field.
What is electricomagnet?
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current ceases.-wikipedia
What magnet is made by electric currents?
All electric currents create magnetic fields. If you wind wire into a coil and pass current through the wire, that is an electromagnet.
What is the magnet formed by the flow of electric current?
When electric current flows, a magnetic field is formed via induction. When copper wire, or another conductor is wrapped around a metal core, it forms an electromagnet.
How do electromagnet get their names?
An electromagnet is only magnetic when an electric current is run through it.
What does a current carrying coil with an iron core make?
A choke, an electromagnet, an electric motor stator, an electric motor rotor, etc. all depending on details of construction and use that are unstated in the question.
What happens when you decrease the current in an electromagnet?
When you decrease the current in an electromagnet, the magnetic field decreases.
How is an electric magnet made?
An electromagnet can be made simply. When an electric current flows in a wire it creates a magnetic field around the wire. By winding the wire into a coil we can strengthen the magnetic field. Electromagnets are made from coils like this.
Is there a magnet in an electromagnet?
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current ceases. Take a look at this Wikipedia page for more information: http://en.wikipedia.org/wiki/Electromagnet
