The way artificial harmonics are executed using the right hand thumb usually means the harmonic sounded is the 4th, 5th, or 6th harmonic, which is going to be very high-pitched compared to non-harmonic notes played at the same location on the left-hand. For this reason, they are often called ''squeals'' or ''squealies''.

This is what is most commonly referred to when saying "artificial harmonic". This technique uses a slighted tilted picking hand to allow the thumb to touch the string as the pick plucks it. The thumb acts as a pivot point to create the harmonic, just like the left-hand finger for a natural harmonic. And again like natural harmonics, you want to lift the thumb off the string as soon as the harmonic is sounded. Usually its just a normal picking motion, but you add the thumb.

For this technique to work correctly, you must focus on pressure, timing, and accuracy. You must use enough right hand thumb pressure on the string to deaden that point on the string but not so much that you end up muting the string instead of simply deadening the pivot point. Your thumb must touch the string at the appropriate time - right before the pick plucks the string or right after (basically at the exact same time), and it must be pulled off the string as soon as possible after plucking the string with the pick. Finally, the location of your right thumb (the pivot point) must be correct. This will depend both on which harmonic you are trying to sound, as well as what fret your left hand is fretting.
