Hi  all
I got a coil and magnet from Larry today and I was wondering what  the
voltage level of the coil is. But the coil is 9000  ohms.



Hi Jon,
 
    You need to place the centre of the coil at about  the 1/2 peak field 
position of the U magnet. Without measuring your magnet, I am  not sure how far 
from the plane of the polepiece this is. If you can set up your  arm to 
oscillate over ~a mm, you might move the two nearer together until you  get the 
maximum recorded signal? There should be a 'known distance', but I don't  know what 
this is. Which magnet are you using?
 
    Regards,
