A coil of wire with an electric current in it?
A solenoid. An electromagnet is wire wrapped around a core of iron (usually). The wrapped wire itself is called the solenoid.
What will happen if a wire is wrapped around a nail a lot of times?
If the nail is iron and you pass an electric current through the wire then you have an electromagnet.
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.
Can electromagnets be turned on and off easily?
Yes.Electromagnets turn on when an electrical current is sent through the wiring wrapped round the iron core. It ceases to be magnetised when the current is turned off.
Produced by a coil of current-carrying wire wrapped around an iron core?
It makes an electromagnet.
How do generators produced electricity?
Wire is wrapped around a core. This is rotated inside a magnetic field so it alternates the direction of the flow of electrons. This causes the electric current.
What is a core wrapped in a wire that is carying electric current is called?
A solenoid
When an electric current is run through wires wrapped around an iron core creates what?
Electromagnetism
Electric current that moves through a coiled wire wrapped about a piece of iron creates?
Magnetic field.
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.
A coil of wire with an electric current in it?

What will happen if a wire is wrapped around a nail a lot of times?
If the nail is iron and you pass an electric current through the wire then you have an electromagnet.
Who discovered electromagnets and when did he discover?
Adam Schaffer discovered the electromagnet in 1806 when he accidentally wrapped an electric current around his saucepan. it was really exciting
How do you use electromagnet in a sentence?
Electromagnetism occurs when an electric current is sent through a coil of copper wire that is wrapped round an iron core.
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.
Why electric not attract iron objects when current is passed through it?
Any electric current does generate a magnetic field, but it might be a very weak magnetic field that you would not notice. In order to create a powerful electromagnet, wire is wrapped around a ferromagnetic core, typically hundreds or thousands of times. Each coil of the wire adds to the magnetic field. But unless the current is extremely strong, a single straight wire produces a magnetic field that's quite weak, but it IS strong enough to deflect a nearby magnetic compass.
Is plastic wrapped around the electric wires is a good conductor?
Plastic wrapped around the wire is insulator. Not a conductor. That is why it is wrapped around the conductor wire.
