Current varies with desired sound. axial intercommunicate in unending magnetic field, coil moves due(p) to motor effect, coil moves cardboard, produces sound. ?Galvanometer:Current flows through with(predicate) coil attached to ricochet and needle. Coil surrounded by magnetic field, moves.

Depending on size of current, moves trough spring stops counteracts the motor affect. beset 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. ? magnetized conflate & fluxion densityoMagnetic flux = mensuration of magnetic field passing through an areao? = BA cos ?? = phi = magnetic fluxB = magnetic field strength (T) = magnetic flux densityA = area...
