Yes true. Even without the iron core as current passes through the coil then the coil would act as a magnetic shell. If the wire is wound in a helical form, then the device is known as solenoid. So with the current in the solenoid it would act as if a bar magnet. If iron core is introduced then the magnetic lines would be concentrated and hence an intense magnet could be produced. The pole of this system will be determined by using 'end rule'.
What else can I help you with?
A piece of nonmagnetic metal that becomes magnetized when an electric current flows around is called?
The piece of metal is called a ferromagnetic material, and the phenomenon where it becomes magnetized when an electric current flows around it is known as electromagnetism.
Why does a electromagnet work?
An electromagnet works by creating a magnetic field when an electric current flows through a coil of wire. This magnetic field attracts ferromagnetic materials, such as iron, causing them to be magnetized temporarily as long as the electric current is flowing.
What type of energy flows through a wire?
Electric energy flows through a wire when an electric current passes through it.
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 formed around the conductor whenever an electric current flows through a conductor?
A magnetic field is formed around the conductor when an electric current flows through it. The strength of the magnetic field is directly proportional to the magnitude of the current flowing through the conductor.
A piece of nonmagnetic metal that becomes magnetized when an electric current flows around is called?
The piece of metal is called a ferromagnetic material, and the phenomenon where it becomes magnetized when an electric current flows around it is known as electromagnetism.

What is A tempoary magnet made when electric currents flows through a wire wrapped around an iron case?
This is called an elecro-magnet, and it is only magnetized while current is running through it.
Why does a electromagnet work?
An electromagnet works by creating a magnetic field when an electric current flows through a coil of wire. This magnetic field attracts ferromagnetic materials, such as iron, causing them to be magnetized temporarily as long as the electric current is flowing.
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.
What type of energy flows through a wire?
Electric energy flows through a wire when an electric current passes through it.
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.
What is a path through which electric current flows?
"circuit"
What flows through an electric circuit?
An electrical current.
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.
When too much current flows through a condutor it is called a?
electric current
