Yes, you would need an electric lamp to read the music when it's dark.
fan converts electric energy into magnetic and further mechanical energy
Several ways. Mechanical Energy to Electrical Energy: Generators and Alternators Chemical Energy to Electrical Energy: Batteries Fuel Cells Thermal Energy to Electrical Energy: Thermocouples
chemical energy
the MRT trains make use of electrical energy to change into mechanical energy
Kinetic energy to electrical energy
There is really no way to make energy - do some reading about the Law of Conservation of Energy for more details. With a magnet, you can convert one type of energy into another - mechanical energy into electrical energy, or electrical energy into mechanical energy.
It uses electrical energy to make thermal energy.
Electrical energy
A turbine.
Electrical to Mechanical
The energy that is used to make a machine run is electrical energy.
The mechanical energy is one type of energy. It can be converted into electrical energy.
