Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
This device converts mechanical energy (kinetic) to electrical energy. It produces an electrical current when the iron core (which has a wire wrapped around it) is rotated near a magnet pulling electrons making electricity flow.
A
electric motor
B
generator
C
turbine
D
None of the above
Explanation: 

Detailed explanation-1: -Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy (the energy of motion) into electrical energy.

Detailed explanation-2: -An electric generator is a device used to convert mechanical energy into electrical energy.

Detailed explanation-3: -The most common device for changing electrical energy into mechanical energy is the motor. Most motors use electromagnets to cause mechanical rotation, which can do work.

Detailed explanation-4: -A generator converts mechanical energy into electrical energy, while a motor does the opposite-it converts electrical energy into mechanical energy.

Detailed explanation-5: -An electric generator is a device that changes kinetic energy to electrical energy through electromagnetic induction. Electromagnetic induction is the process of generating electric current with a magnetic field.
