Solution

The device used for producing electric current is called a generator.

Explanation:

  • A generator is a device that transforms mechanical energy into electrical energy.
  • A galvanometer is a device that detects the existence of electricity in a circuit.
  • An ammeter is a device that measures the amount of electric current flowing across a circuit.
  • A motor is a piece of machinery that turns electrical energy into mechanical energy.

As a result, the generator is the correct solution.
