Hi Dave,|
What a great idea. A question ...
Are the magnets loose in the packet? Im interested in how much vibrational movement space there is between the magnets and the pickup that will allows microphone emf (coil/magnet) generation?
thanks,
JEFF
Yes, the magnet is inside the bubble package. There is more here then what appears at first. I designed this simple setup so the average person can explore the 'Bloch Wall' http://en.wikipedia.org/wiki/Bloch_wall
There is also a magnet inside the induction microphone along with a coil. The external packaged magnet sets up a counterforce with the coil about in the center...fun stuff to explore.
Have fun,
Dave
