Aren't the hundreds of volts induced in the primary as a result of the rapid
interruption of the primary current?
Therefore, if the rate of change in the primary current was sufficiently
fast wouldn't the above requirement be fulfilled, and  wouldn't a bipolar
square wave,with a fast rise and fall times, be sufficient to do this?
