Circuit setups for pulse motors

Gidday everyone, just a quick message to let you know I've posted a bit more info re Hall controlled circuits on my web site.

Thanks Toad. Great pages.
1.) If you have two magnets attracted to each other and a coil in between them, as the magnets come towards each other, is there a current induced in the coil?

2.)Will you be dealing with BEMF vs. "flyback current"?

3.) Would you upload your images as jpeg's?

Hi Tropes, in answer to your questions.

1. Yes, but only while the magnets are moving. Either in toward the coils or out away from the coils. When movement ceases, so will the induced current. By the way current will only arise if there is a load on the coils. But with or without a load, there will be an induced voltage
2. Flyback current is just another expression for CEMF, but there are also circuits which redirect the current in a way which can best be described as FlyForward. They both are derived from CEMP. And I will address both Flyback and Flyforward on my web site soon.
3. I can upload my images as jpegs, but I'm using swf to preserve as much clarity in the drawings as possible. If you would prefer, and don't mind sending me a real email address through posting here, I can post the images to you directly for you to do as you wish with them.
I don't really want to expose my real email address openly on the forum, but will send it freely to those whom I deem genuine in their desire to experiment for themselves and learn what they will.

Cheers

1. You must mean " but only when the magnets are moving". The coil is stationary. Because of the attraction, they are moving towards the coil.
2. If a coil is placed around these magnets as the are drawn towards each other there is also a current induced. see  http://www.theowlnest.com/opm.html

Hi again Tropes,

"2. If a coil is placed around these magnets as the are drawn towards each other there is also a current induced. see  http://www.theowlnest.com/opm.html"

Yes, but the field of the magnet over which each coil is wound will tend to override the changing fields between them and reduce significantly the voltage and/or current produced by the effect of changing magnetic fields between the 2 moving magnets
