This is a model tractor i built from a 1963 pfaff sewing machineThis is something i've wanted to make for a long time and finally got it done! the sewing machine i used for this was beyond reasonable repair and had been set aside as a parts donor so it was a great candidate for a new life as a tractor.
This magnetic field is induced into the iron core to form an electromagnetMaking an electromagnet at home can be quite amusing as after completing the procedures you can not only see it really working but also learn through experiments regarding its practical applications in various fields.
When the coil moves it pushes and pulls on the speaker coneThis vibrates the air in front of the speaker creating sound wavesThe electrical audio signal can also be interpreted as a waveThe frequency and amplitude of this wave which represents the original sound wave dictates the rate and distance that the voice coil moves.
