How does a DC motor work?
Answer : A DC motor works based on the basic principle of electromagnetism. When an electric current passes through a conductor (like a wire), it creates a magnetic field around that conductor. This is the basic ... the armature keeps turning in the same direction. That's the basic working of a DC motor!...
