A coil is a long, flexible object that is wound in a spiral shape. It can be made of many different materials, including wire, rope, or string.

In science, the word coil is often used to describe a spring or a solenoid. A spring is a coil that is used to store energy. A solenoid is a coil that is used to create a magnetic field.

Coils are used in many different devices, including motors, generators, and transformers. They are also used in some medical devices, such as MRI machines.

Imagine that you are a snake. You are long and flexible, and you can coil your body around things. You are like a coil. In the same way, a coil is a long, flexible object that can be coiled around things. This makes it useful for storing energy or creating a magnetic field.

The spring was made of a coiled wire.
