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 colour does argon go when an electrical current runs through it?
When an electric current is passed through Argon, it becomes blue
What is an electromanget?
An electromagnet is a type of magnet that is created by passing an electric current through a coil of wire. The coil acts as a magnetic field when an electric current is passed through it, and becomes magnetic when the current flows. Electromagnets are used in a variety of applications, such as electric motors, MRI machines, and magnetic levitation trains.
What are parts of an electric motor repels the poles of the permanent magnets?
In an electric motor, the parts that repel the poles of the permanent magnets are the armature or rotor windings, which carry electric current. When current flows through these windings, it generates a magnetic field that interacts with the magnetic field of the permanent magnets. Depending on the orientation of the current, the like poles of the magnetic fields repel each other, creating rotational motion. This interaction is fundamental to the operation of the motor, allowing it to convert electrical energy into mechanical energy.
When an electric charge moves through a conductor there is an electric in the conductor?
When an electric charge moves through a conductor, an electric current is generated in the conductor. The flow of electrons creates a flow of current in the conductor, which is the movement of electric charge through the material.
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.
When a current passes through a resistance what is the electric energy that is lost?
Becomes heat.
What does not contain in a electromagnet?
An electromagnet does not contain permanent magnets. It consists of a coil of wire wrapped around a ferromagnetic core, such as iron, that becomes magnetized when an electric current flows through the coil.
What is the definition of eletro magnet?
A magnet that becomes energised when an electric current is passed through it.
Is electromagnet a permanent magnet?
No, an electromagnet is not a permanent magnet. It is a magnet that produces a magnetic field when an electric current is passed through it, and the magnetic field disappears when the current is turned off.
What is lighting effect of current?
When electric current is passed through a conductor ,it becomes very hot and emits light. This is called the lighting effect of current.
How are electromagnets and permanent magnets different?
Electromagnets are temporary magnets that produce a magnetic field when an electric current flows through them, while permanent magnets retain their magnetism without the need for an external electric current. Electromagnets allow for the control of the magnetic field strength by changing the current, while permanent magnets have a fixed magnetic strength.
How is a electromagnet diffrent then a permanent magnet?
An electromagnet is a temporary magnet that only produces a magnetic field when an electric current is flowing through it, while a permanent magnet retains its magnetism without needing an external electric current. Additionally, the strength of an electromagnet can be easily adjusted by changing the amount of current flowing through it, while the strength of a permanent magnet is fixed.
An electromagnet is a type of what?
An electromagnet is a type of magnet that becomes magnetic when an electric current flows through it and loses its magnetism when the current is turned off.
What is effect of lights?
When electric current is passed through a conductor ,it becomes very hot and emits light. This is called the lighting effect of current.
What colour does argon go when an electrical current runs through it?
When an electric current is passed through Argon, it becomes blue
What part of an electric motor repels the poles of the permanent magnets?
The armature of an electric motor is the part that repels the poles of the permanent magnets due to the flow of electric current through the conductors in the armature, creating a magnetic field that interacts with the magnetic field of the permanent magnets to produce motion.
