I'm a little confused about ampere's law (pretty sure i saw it on the list of ps topics). Is it just saying that the more magnetic field there is around a wire, the larger the current in the wire?

Magnetic field strength is proportional to current and is inversely proportional to distance from wire. The current produces the magnetic field, not vice versa.
