A method is provided for testing magnetic bits (3, 104, 514) of an array. A train of first (702), second (704), and third (706) pulses is provided to a desired bit, the first and second pulses beginning at a substantially similar low field and increasing in similar amounts with respect to successive trains of the first, second, and third pulses, the third pulse having a current amplitude sufficient to toggle the magnetic bit. A representative count is recorded in response to switching of the bit. The above steps are repeated and a determination is made of the current amplitude required to write and toggle the bit.
