What devise consists of a core of iron surrounded by a coil of wire?

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.


The inner core consists of what?

iron


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.

Which device consists of two separate coils of wire wrapped around an iron ring?

A transformer consists of two separate coils of wire wrapped around an iron ring. The primary coil induces a changing magnetic field in the iron core, which in turn induces a voltage in the secondary coil. This allows for the transfer of electrical energy between the two coils.


What is Tapped Iron Core Coil?

A tapped iron core coil is a type of inductor with multiple connection points along the coil windings, or taps. These taps allow for different sections of the coil to be accessed, making it possible to vary the inductance and impedance of the coil. Tapped iron core coils are often used in applications where flexibility in tuning the inductance is required.
