The device you are referring to is an electromagnet. When an electric current passes through the coil of wire, it creates a magnetic field in the iron core, which then acts like a magnet. This property is commonly used in various applications such as in electric motors and relays.
What else can I help you with?
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 an electromagnet with a fixed core called?
An electromagnet with a fixed core is called a solenoid. It consists of a coil of wire wrapped around a metal core, typically made of iron, and produces a magnetic field when an electric current passes through the wire.
What makes an electrognet stronger that a solinoid?
The strength of an electromagnet is determined by the number of coils wrapped around the core and the amount of current passing through the coils. A solenoid is a type of electromagnet that consists of a coil of wire wrapped around a core, so the strength of the solenoid can be increased by increasing the number of coils or the current passing through the coil.
Is the core of an electromagnet a piece of steel put in the center of the coil?
no
What magnet is uses to produce electricity?
An electromagnet is commonly used to produce electricity. It consists of a coil of wire wrapped around an iron core. When an electric current flows through the coil, it creates a magnetic field that can induce an electric current in nearby wires or coils.
A what consists of a coil with an iron core and a movable iron bar?
A relay.
What consists of a coil with an iron core and a moveable iron bar?
A relay.
What is elelctromagnets?
Electromagnet is a device consisting of a core of magnetic material such as iron, surrounded by a coil through which an electric current is passed to magnetize the core.
Working of a capitance and coil?
A ferrite core inductor with two 47 mH windings. An inductor usually consists of a coil of conducting material.
What consists of a coil with an iron core and a movable iron bar?
A coil with an iron core and a movable iron bar constitutes an electromagnet. When an electric current flows through the coil, it generates a magnetic field that attracts the iron bar, causing it to move. This device is commonly used in various applications such as in electric motors and doorbells.
What is the farthest point inside the earth called?
The farthest point inside the Earth is called the Earth's core, which consists of a solid inner core and a liquid outer core. The solid inner core is made mostly of iron and nickel and is surrounded by the liquid outer core.
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 does the ignition coil look like?
An ignition coil generally looks like a cylinder with a second cylindrical temp at one end. On top of that same and, there are two primary terminals. Inside of an ignition coil is an iron core surrounded by coils of thin wire.
What does ignition coil look like?

About 1400 km in diameter solid iron and nickel?
The description matches the size and composition of the Earth's core. It consists of a solid inner core primarily composed of iron and nickel, with a diameter of about 1,220 km and surrounded by a liquid outer core.
What does an electromagnet need to generate a magnetic field?
An electromagnet needs an electric current flowing through a coil of wire to generate a magnetic field. The strength of the magnetic field can be controlled by adjusting the amount of current flowing through the coil and the number of turns in the wire coil.
A coil of wires wrapped around a core?
A coil of wires wrapped around a core is an electromagnet.
