What aspect of the field is different in one place relative to another
place
for the wire to have potential generated when it is moved between these
places
when the intensity of the field is the sane?

| 
| 
| 
| If Magnet is spun but disk and wires stationary! No voltage.
| Theory: If magnetic field does NOT rotate with magnet, then there is

| there is no output.
| 
| Theory II: If magnetic field DOES rotate with magnet now there is a

This is because we have those hookup wires crossing the extraneous field.
A modification of the disk design can avoid this.
