It is called an armature.
A relay is made up of a coil with an iron core and a movable iron bar. The movable iron bar in a relay is called a switch.
A relay.
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.

A relay.
The armature.
The core of a relay is typically made of soft iron because it has high magnetic permeability, which allows it to create a strong magnetic field when a current passes through the coil. This strong magnetic field helps to attract and hold the movable armature in place, enabling the relay to switch electrical circuits on and off effectively.
A iron bar is a conductor
A iron bar is a conductor
a "capo" or "clamp"
you have to mine iron ore then put it in a furnace and you will get an iron bar called an iron ingot.
You can differentiate between a bar of iron and a bar of copper by testing their magnetic properties - iron is attracted to magnets, while copper is not. A bar magnet will attract small iron objects, while a bar of copper will not be attracted.
