Magnetic field is generated by current, not voltage. Current is
generated by voltage potentials. The voltage itself has does not
create the magnetic field and is not a factor. You can have 10 volts
or 1,000,000 volts and still end up with the same magnetic field. It
is current, not voltage. Check out some basic physics books and
perhaps the following web page will help you.

The Electric fields in a transformer are generated by di/dt. "di" is
a change in current. "dt" is a change in time. Let me know if you
need help learning about this and I'll try to find you a web page for
educational purposes.
