hi all,
can any one help me to provide circuit diagram and technical detail to build a impulse type loudspeaker magnet charger to charge ceramic or Neodymium magnet assembly size up to 285 mm, maximum loudspeaker size is 18".
           Is there anybody at this forum who have realy seen a loudspeaker magnetizing fixture or could describe it in words (inductans, ohms, turns,voltage,currents etc)
                                                  thanks moderator.

Not exactly a home project.

Take a look at the size and weight of the machine, and its currents, in a magnetizer you can buy http://www.magnetomachinery.com/pdf/magnetizer/The-High-Power-Magnetizing-Power.pdf

Why can't you get your magnet supplier to do the magnetization?
