Dear Guru Engineers,
I made 650 coils round a ferrite rod of cirumference about 2cm using super thin (like hair) copper wire that is insulated by some kind of yellowish golden orangy 'lacquer'. I hope you get the picture what i am trying to describe here :p
Anyways, i used a strong magnet and oscillated it up and down the shaft of the ferrite rod.
I sandpapered the ends of the wires terminating on the rod and hook them up to the amp-meter. nothing. seemed like no current produced at all??
pls could you explain what could be the problem and was my method wrong?
sincerely
Ramone
