If you used a nickel core for an electromagnet, then the strength of the field produced would be drastically improved. However, iron has a relative permeability of 5,000 when it is 99.8 percent pure, and the relative permeability of soft iron with 99.95 percent purity is a massive 200,000. This huge relative permeability is why iron is the best ...
