what does coil mean

Coil primarily refers to something wound into loops or spirals, like rope or wire, and serves as both a verb (to wind) and noun across everyday, technical, and medical contexts.

Core Definitions

A coil forms when material twists into rings, such as a coil of rope on a ship or garden hose neatly stored. As a verb, it means to wind something circularly—"She coiled the extension cord around her arm." Dictionaries highlight its spiral shape, evoking images of a snake ready to strike or hair curling tightly.

Technical Uses

In electricity, a coil consists of wire turns creating magnetic fields, powering electromagnets, transformers, or induction coils in motors. Picture a solenoid: a cylindrical coil moving a plunger via current changes, vital in car ignitions or door locks. Choke coils manage inductance in circuits.

Medical Context

Coil commonly names an intrauterine device (IUD), a small T-shaped coil preventing pregnancy by releasing hormones or copper—over 14% of U.S. women use them as of 2025 data. "She got a coil fitted last week," notes forum chatter on contraception choices.

Everyday Examples

• Rope or hose : Wound for storage—"Coil the hose before winter."
• Hair : Tight coils describe curly textures in beauty trends.
• Figurative : "Mortal coil " from Shakespeare means life's troubles, as in "shuffle off this mortal coil."

Idioms and Phrases
