Hummm... An inductor produces a current that is proportional to the
integral of the voltage. If a constant voltage is applied over an
inductor, the initial current is zero, and increases linearly with
the time. So, it doesn't slow down the current as it builds up the
magnetic field, but increases it in proportion to the magnetic field.

Ok.
