I building a magnetic repulsion motor and was wondering what materials would 
provide the strongest electromagnetic poles for repulsion. North to North 
electromagnets. I am currently using a standard steel bolt for the cores. Also 
what kind of effects would the bismuth have on the back emf of the collapsing 
field.
