A current-carrying wire with many loops is called solenoid.
Step-by-step explanation:
A current-carrying wire is a conductor. When it is turned into a coil for better use, it is called a solenoid. A solenoid has specific features. Since it is wrapped up in many turns, it creates a magnetic field inside. They also convert electric current into mechanical work or action.
The solenoid may or may not be straight. Anything wrapped into a coil is a solenoid. While the study, the length of a solenoid is taken greater than the diameter. And the shape is called a helix.
