This video shows the two magnets clearly and has Sean describing the orbo and explaining the significance of some lines on a scope. http://www.youtube.com/user/SteornOfficial#p/u/0/S5nae_I_Mus
The magnetic field experienced by the torroid coil is characteristically inhomogeneous in time and space since the magnets are metalic discs and they are whizzing past the coils. For the coil to experience a homogeous magnetic filed, the magnet would have to be in the shape of a continuous metalic belt around the rotor. harry ----- Original Message ---- > From: Terry Blanton <[email protected]> > To: [email protected] > Sent: Thu, December 31, 2009 8:44:07 PM > Subject: Re: [Vo]:Steorn Replication > > If you check carefully, Steorn uses two magnets to help make the field > homogeneous. > > > On Thu, Dec 31, 2009 at 7:56 PM, Harry Veeder wrote: > > > > > > > > > > ----- Original Message ---- > >> From: William Beaty > >> To: [email protected] > >> Sent: Thu, December 31, 2009 4:36:48 AM > >> Subject: Re: [Vo]:Steorn Replication > >> > >> On Wed, 30 Dec 2009, Craig Haynie wrote: > >> > >> > By moving a magnetic field across a conductor, don't we get induction, > >> > and hence, electricity? > >> > >> Not in a toroid inductor with unsaturated core.
