Hi All I was wondering , Sean Thomas has described in detail how to construct a speaker style coil for use in a smt8 sensor. Various factors were discussed to improve the strength of the coil/magnet . My question, to Sean Thomas and all, is would the use of ferrite over steel improve the magnet field concentration and therefore sensor performance. I have seen various ferrite shapes. I'm not sure how well it machines. Regards Barry __________________________________________________________ Public Seismic Network Mailing List (PSN-L)
