how to make a disco generator
things you need for it are a wooden board ,two old c.d,a machine bobbin,glue,l.e.d bolt nut,washers,thin insulated copper wires,disk magnets and a lid.
first make a 500 turn insulated copper wire coil and scrape its end and attach to L.E.D..make 5 such sets.
on on old c.d paste 4 strong disk magnets on its diameter end and paste a washer on its
center. On wooden board paste old c.d and paste bobbin with washer and nut at center .Now paste coil and l.e.d combination on diameter ends.
Now place the magnet disk containing c.d on the another c.d . Place handle . Now rotate upper c.d in a dark room and see the fun.
PRINCIPLE BEHIND IT ........
This project work on electromagnetic induction..
"when a magnetic field embracing a conductor moves relative to the conductor, it produce a
flow of electrons in the conductor. This phenomenon whereby an e.m.f. and hence current is
induced in any conductor which is cut across or is cut by a magnetic flux is known as
electromagnetic induction". This law was stated by faraday.
