this demonstrator surrounds a central magnet with 46 small compasses that align in a flowing dipole pattern

sized to read single-cell and small-battery-pack voltages without scale-overshoot risk

and integrated stirrer for liquid mixing

dimensioned to slot into PH0651 optical-bench holders for repeatable image-formation

supporting three-rope compound arrangements for advanced mechanical-advantage investigations
