Current varies with desired sound. axial intercommunicate in steadfast magnetic field, coil moves overdue to motor effect, coil moves cardboard, produces sound. ?Galvanometer:Current flows by means of coil attached to retract and needle. Coil touch by magnetic field, moves.

Depending on size of current, moves trough spring stops counteracts the motor affect. chevvy points to size of current. The generator?Faraday?s discovery of induction. oMoved a magnet near a coil of wire. oCurrent produced only when the magnet was in relative motion to the coil. ? magnetised conflate & magnetic field densityoMagnetic flux = mensuration of magnetic field passing through an areao? = BA cos ?? = phi = magnetic fluxB = magnetic field strength (T) = magnetic flux densityA = area...
