hi gang,
Just building a seismometer I have 2 x 2.5cm disc rare Earth magnets spaced far enough apart for a coil of wire to move between them.
Would you expect there to be any difference in induced voltage into a coil between 2 magnets when the magnets are orientated to attract or repel ?
I'm thinking no difference, but really have no idea
see pic for idea of what I'm doing. ignore that fact the builder of shown unit is using 4 x disc magnets, 2 top and 2 bottom.
if there is a difference between the two options ... why ?
cheers
Dave
