2. If you wanted to create a voltage source using magnetic induction, which device would you use?

A. Battery

B. Thermocouple

C. Dry cell

D. Generator

The correct answer is D. If I wanted to create a voltage source using magnetic induction, I would you use a Generator.

Explanation:

The purpose of the magnetic induction generator is to transform mechanical energy into electrical energy through the relative movement between a coil formed by electrical conductors and a permanent magnet that supplies a magnetic field.

The physical principle applied is based on the Faraday Law or Faraday-Lens Law.

Some generators have the permanent magnet in the rotor (rotating mobile part around its axis connected to a motor) and the winding in the stator (fixed part that surrounds the rotor) and others in reverse have the winding in the rotor and the permanent magnet on the stator.

The rest of the devices use physical principles other than magnetic induction: batteries and dry cells transform chemical energy into electrical energy and thermocouples transform caloric energy into electrical energy.
