Don't lie to me, boy.
Whenever I install a bike computer (and I've done hundreds) I try to place the magnet on the top part of the wheel when it stops spinning. That's generally near the valve stem. The hole for the valve stem makes that side lighter. The steel pins that hold the rim seam together make that side heavier.
