Transformer

1. Take a torus of metal, such as iron.
2. Wind a wire around one side of the torus for n1 turns.
3. Wind a different wire around the other side of the torus for n2 turns.
4. Apply some current to the first wire. i amps * n1 turns * C constant = B Teslas induced in the torus.
5. The torus acts as a circuit for the magnetic field, so the same B Teslas are induced in the other coil.
6. B teslas / ( n2 turns * C constant ) = i2 amps induced in the second coil.
7. So: i2/i = n1/n2.
8. Since power must be conserved, Vout/Vin = n2/n1.
