Current varies with desired sound. axial intercommunicate in fixed magnetic field, coil moves cod to motor effect, coil moves cardboard, produces sound. ?Galvanometer:Current flows through coil attached to move and needle. Coil border by magnetic field, moves.

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