    Undergrad Electric Generators: Iron Core for Larger Current?

    Let's see here. We have the following from Ampere's law: B = mu NI/h Solving this for the current, we get: I = Bh/(N mu) Where mu depends on the core material. Using iron (or most other metals) this value will be greater than mu_nought = 1/(4pi x10^-7) ~ 1.2566650×10^-6. The movement of...
