Hey, am doing a physics student directed prac task thing, (dont worry ive done all the work dont need you to do ym assignment for me etc)
im constructing faraday's original disc dynamo, where i have two neodinium magnets setting up an electromagnetic field, and by rotating a copper disc in the field, a emf should have been produced.
I've got the disc wired to a voltmeter/ammeter and it detected neglible amounts of reading.
The only thing i can think of preventing a proper reading would be the fact that i didnt use a copper disc, it was aluminium, (non magnetic, but still conducting).
Initially i tested the piece of metal and it was an efficient conductor, but a friend suggested that it may be due to the fact copper has less resistance than aluminium.
any ideas?
