What is the output of the Hall effect sensor when there is not a magnetic field present?

No Hall voltage is produced when there is no magnetic field. The Hall effect creates a voltage across a conductor only when a magnetic field perpendicular to the current deflects charge carriers. Without that field, the deflection doesn’t occur, so the Hall voltage is zero (ideally). In real sensors you might see a small offset or noise, and some designs bias the output differently at zero field, but the fundamental result is that the output voltage is zero in the absence of a magnetic field.
