That can be a 'solenoid' or an 'electromagnet'.
An electromagnet is a device formed from an iron core wrapped in current-carrying wire. When an electric current flows through the wire, it creates a magnetic field in the iron core, allowing it to attract or repel other magnetic materials.
A coil of wires wrapped around a core is an electromagnet.
An electromagnet typically has a magnetic core, such as iron, and is energized by running an electric current through a coil wrapped around the core. When the current flows, it generates a magnetic field around the core, giving the electromagnet its magnetic properties.
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 wrapped around an iron core produces an electromagnet. When electric current flows through the coil, it creates a magnetic field. This electromagnet can be used in various applications, such as lifting objects or generating mechanical motion.
Electrical charge can be produced from an electromagnet. This is a core i.e. iron wrapped in a wire coil. A magnetic device then passing by can cause an electrical charge to be produced, typically AC (alternating current).
A solenoid
A yarn in which one type of fiber is twisted or wrapped around another fiber that serves as a core.
This is a basic description of an electromagnet. Apply a voltage (direct current) to the coil, and a magnetic field will develop around the coil and be "conducted" through the iron core to create that electromagnet.
A coil of wire or a coil in the shape of a cylinder is a typical shape for an electromagnet (or a solenoid). The strength of the magnetic field of an electromagnet can be increased significantly if the coil is wrapped around an iron core. This configuration may be called an inductor when used as an element of an electrical circuit.
