How does it work?
A generator is a device converts mechanical energy in to electric energy. It works on the principle of electromagnetic induction. When a coil of insulated wire is rotated in a magnetic field, an electromotive force is induced in it and because of this a current called induced current will flow through the electrical appliance connected with the terminals of the coil. The terminals of rotating coils are connected to external appliance through connecting brushes using slipping contacts.
How does it apply or use magnetism?
It uses permanent magnets creating magnetic field, due to this field because of electromagnetic interaction induced current will flow through the rotating coil. According to Lenz law the direction of induced current is such that it opposes the cause by which it produced. Here the ...
