Why are metals good conductors of heat and electricity

Agenerator converts mechanical energy to electrical energy. when a coil placed between two magnets rotates, the magnetic lines of force are disturbed. this induces a current in the coil. the image below shows a generator. what could be done to make the lamp brighter? a. decrease the size of the magnets b. turn the coil slower c. change the polarity of the magnets d. turn the coil faster
