First hello ,this is my very first posting in any web site ever since I start using the internet 14 years ago ,i have been looking for an answer for 40 days and still counting.
i am using a signal generator to drive a coil back and forth on a pole between 2 magnets ,but the current i am getting is too small 4mA with square wave voltage +- 20v.
is there any way i can increase the current say to .5A or maybe 1A, but still using the signal generator, or if anyone know a way using switches to reveres polarity so I can use an external current source.
plz check this link to say what I am trying to replicate but i dont wanna use any more power than i should .http://www.youtube.com/watch?v=Famr4YWBE7g&playnext_from=TL&videos=YBHThnM-Fzg
thank you in advance.
