Figure 1 shows a laboratory apparatus used to model a planet's magnetic field. A spherical "Planetary Core Model" contains a strong vertical bar magnet with its North ( $N$ ) and South ( $S$ ) poles oriented as shown. Two mobile monitoring probes, Probe Alpha and Probe Beta, containing sensitive miniature magnetic compass needles, are positioned directly above and below the core respectively.

Figure 1: Laboratory planetary magnetic field simulation. A central sphere labeled 'Planetary Core Model' contains a vertical bar magnet with the North pole at the top and South pole at the bottom. Probe Alpha is positioned directly above the North pole, and Probe Beta is positioned directly below the South pole. Both probes contain small magnetic compass needles.

State and explain the direction in which the north-seeking pole of the compass needle points in both Probe Alpha and Probe Beta relative to the planetary core.
